Town of Northport

Land Use/Current Shoreline Master Program Land Use Designation:

• Rural

Current zoning designation:

• Residential, Industrial, and Exempt

Current Shoreline Master Program Environment Designation:

• Unavailable – The Town does not have an existing Shoreline Master Program (SMP).

Existing Land Cover/Development The Northport Reach shoreline is mostly forest and shrubland; about a quarter of the shoreline is developed, consisting mostly of roads and railroads within railroad right-of-way, with two homes located partially within jurisdiction.

Geomorphic Character Description – Franklin D. Roosevelt Lake lies within a valley comprising continental glacial outwash sediments. River levels can fluctuate based on downstream dam operations. The shoreline consists of mostly low banks throughout the reach.

Hardened Banks – Approximately 1,700 feet of hardened banks exist in the Northport Reach and are associated with the Burlington Northern Santa Fe (BNSF) railroad alignment.

Flooding and Geological Hazards Flooding – Flooding is regulated by Grand Coulee Dam operations and controls located downstream in addition to reservoirs located upstream in Canada that store floodwater in accordance with the Columbia River Treaty. Federal Emergency Management Agency (FEMA) floodplains are mapped along the bank of the Columbia River at the Town of Northport. The floodplain extends along the shallow shoreline but is confined by the steep banks up to the Town of Northport.

Geological Hazards – Areas with erosion-hazard areas exist along the channel margin. A minor amount of steep slope landslide hazard area exists within the reach. One gold placer mining permit is identified in the Washington Department of Natural Resources (WDNR) mine database within this reach (Note: Presence of a mining permits does not mean active mining activity occurring. Additionally, mining permits include recreational placer mining use). No known active faults exist along this reach.

Existing Public Access Northport park provides a boat launch, boat moorage, and parking facilities. There is also a river boat dinner cruise. Many informal public access points are available in this reach. This reach is also a popular location for recreational mineral prospecting.

Identified Public Access Improvements No new improvements have been identified.

Public Access Opportunities Opportunities for public access are limited due to railroad paralleling the shoreline.

Ecological Conditions

Water Quantity and Sediment There are no tributaries along Northport Reach 1. USGS flow data are not collected in this reach. However, flow data are collected in the Columbia River upstream in Columbia River Reach 1 (USGS Gage #12399500). Based on historical records, peak flows in this reach occur during the summer, and low flows occur during the late fall and spring. Runoff from local roads may contribute flow into the river during the wet season and during periods of snowmelt.

Sediment sources throughout the reach include steep, erodible glacial outwash banks (in SR 1a) and soils prone to erosion. Sediments are likely accumulating throughout this the downstream end of this reach because the river is managed as a lake impounded by the Grand Coulee Dam downstream. Although sediment inputs are likely reduced from upstream dams, sediments are likely accumulating at the upstream end of Lake Roosevelt, which begins upstream of Northport. Sediment input sources likely include tributary inflow upstream of Northport. In addition, the draft of Columbia River (Lake Roosevelt) levels may cause some movement of sediment.

Water Quality Northport Reach is a water of concern for pH and temperature. This reach also requires a Total Maximum Daily Load (TMDL) for 4, 4’-DDD, 4, 4’-DDT, Alpha-BHC, dissolved oxygen, mercury, PCB, and temperature. Water quality is monitored by Department of Ecology Ambient Monitoring Station #61A070. Water quality throughout the reach is likely impacted by historical industrial runoff that settles in sediment.

Habitat Characteristics and Priority Habitat Species Presence There is a minimal amount of shoreline area within the Northport reach that is not developed or stabilized in support of the bridge or railroad. There is a band of riparian forested area along the shoreline that ranges from 20 to 130 feet, and the shoreline is steep at the upstream end, levelling out to include a small part of a floodplain feature at the downstream end. The Northport Reach contains priority spawning and rearing habitat for white sturgeon and is used as wintering habitat for bald eagles.

Ecological Functions Analysis

Level of Existing Function The Northport Reach is designated as Impaired.

Town of Marcus

Characteristics

Ownership Marcus Reach 1 is mostly public ownership (88%) with a majority held by the U.S. Bureau of Reclamation (81%) with about 12% private ownership.

Land Use/Current Shoreline Master Program Land Use and Zoning Designation:

• SR 1a (UGA) – R-1 Residential, and Open Space • SR 1b: Residential and City-owned

Current Shoreline Master Program Environment (SMP) Designation:

• SR 1a (UGA) – Rural • SR 1b – Unavailable. The Town does not have an existing SMP; however, the Town’s

Comprehensive Plan (Town of Marcus 2015) designates the Shoreline Enhancement Overlay as Recreation

Existing Land Cover/Development The Marcus Reach consists mostly of forest land. Development in this reach consists of a boat launch associated with the Marcus Island Campground and residential development within SR 1b.

Geomorphic Character Description – Franklin D. Roosevelt Lake lies within a valley comprising continental glacial sediments that consist of glaciolacustrine deposits and till. Lake levels can fluctuate based on downstream dam operations. The shoreline consists of mostly low banks at Marcus Island to higher bank areas upstream.

Hardened Banks – There are none identified. No artificial hardened banks exist along this reach.

Flooding and Geological Hazards Flooding – Flooding is regulated by Grand Coulee Dam operations and controls located downstream in addition to reservoirs located upstream in Canada that store floodwater in accordance with the Columbia River Treaty. FEMA floodplains are established in SR 1a (UGA). The floodplain extends along the shallow shoreline bank. High banks offshore of the shoreline prevent flooding into the Town of Marcus. FEMA floodplains are not established in SR Marcus 1b.

Geological Hazards – Areas of unstable steep slopes (greater than 30%), landslide hazards, and erosion hazards exist along the lake margin. Steep, unstable slopes are associated with till deposits (SR 1a) and glaciolacustrine deposits (1b). One mining permit for a gold placer mine is located within this reach. No known active faults exist along this reach.

Appendix A




Town of Marcus

Existing Public Access Marcus Island has a campground, picnic area, and boat launch. The Campground Road provides access to Marcus shoreline before accessing the island. Visual access exists from north of the Overlook Boulevard. This reach is also popular for shoreline fishing.


Public Access Opportunities New public access opportunities are limited due to slopes. Opportunities exist for additional visual access from connections to existing road network.


Water Quantity and Sediment There are no tributaries along Marcus Reach 1. USGS flow data are not collected in this reach. However, flow data are collected in the Columbia River upstream in Columbia River Reach 1 (USGS Gage #12399500). Based on historical records, peak flows in this reach occur during the summer, and low flows occur during the late fall and spring. Runoff from local roads may contribute flow into the river during the wet season and during periods of snowmelt.

Sediment sources throughout the reach include steep, erodible glacial till banks (in SR 1a) and soils prone to erosion. Sediments are likely accumulating throughout this reach because the river is managed as a lake impounded by the Grand Coulee Dam downstream. Sediment input sources likely include tributary inflow. In addition, the draft of Columbia River (Lake Roosevelt) levels may cause some movement of sediment.

Water Quality Lake Roosevelt in the Marcus UGA is a water of concern for PCB.

Habitat Characteristics and Priority Habitat Species Presence The Marcus Reach contains priority wintering habitat for bald eagles.

• Marcus SR 1a (UGA) – This subreach begins at the eastern edge of the Marcus UGA and extends 1.9 miles downstream to its western edge, and extends into the Columbia River, but does not include the opposite shoreline, which is part of SR 2f. The upstream end of the subreach is characterized by steeply sloped erosive banks, which support some riparian trees and shrub growth. Some of this vegetative growth extends over the top of bank and is contiguous with upland forested area. Marcus Island is included in this subreach, as well as a portion of the shoreline adjacent to the Town of Marcus, but is outside of the town boundaries, which do not extend to the water’s edge. Marcus Island is forested and developed for camping. The upstream end of Marcus Island is connected to the mainland under most water conditions. The shoreline adjacent to the Town of Marcus includes the

Columbia River (Franklin D. Roosevelt Lake) – Reach 1

Stevens County

Reach Description This reach begins at the United States-Canada border and extends 10.2 miles downstream to the western boundary of the Town of Northport at the southwest corner of T39N_R40E_S05 (this reach does not include the portion of the Columbia River with the Town of Northport).

Shoreline Jurisdiction 1,809 acres


Subreaches (SRs); see Map 1: There are no subreaches located in Columbia River – Reach 1.

Appendix A




Stevens County

Characteristics

Ownership Reach 1 is mostly private ownership with a small amount (less than 10%) of public and tribal ownership.


• Rural and Forest


• NR Forest, RA-20, and RA-5


• North shoreline is Rural • South shoreline is Rural

Existing Land Cover/Development Reach 1 consists mostly of forest and shrubland; there is minimal development except roads and railroads.

Geomorphic Character Description – This reach lies within a valley comprising continental glacial outwash with minimal areas of bedrock along the left and right banks. Bedrock is found along the right bank and consists of metavolcanics of the Rossland Group, acidic felsic intrusive rocks (Sheppard Granite), and marine metasedimentary rocks. River levels can fluctuate based on upstream and downstream dam operations.

Hardened Banks – There are none identified. No artificial hardened banks exist along the lake shoreline. The south bank shoreline in this reach includes some areas that have been stabilized for the protection of the railroad bed.

Flooding and Geological Hazards Flooding – Flooding is regulated by Grand Coulee Dam operations and controls located downstream in addition to reservoirs located upstream in Canada that store floodwater in accordance with the Columbia River Treaty. The regulation area begins approximately 5 miles downstream of the United States-Canada border. FEMA floodplains are mapped throughout the reach, but floodways are not. The floodplain is confined in the upstream sections of Reach 1. The floodplain widens at a bend upstream of the confluence of Reach 1 and Deep Creek, inundating the inside of the bend. The floodplain is moderately wide at the confluence of Reach 1 and Deep Creek.

Appendix A




Stevens County

Geological Hazards – Areas of unstable steep slopes (greater than 30%), landslide hazards, and erosion hazards exist along channel margins of the right and left banks throughout the reach and are mostly associated with the continental glacial outwash deposits and a minor amount with mass wasting deposits and till. Four mining permits are identified in the WDNR mine database—three for gold and one for copper. No known active faults exist along this reach.

Existing Public Access A swimming beach is located near the Upper Columbia RV Park and Campground upstream of Deadman’s Eddy. This reach is also a popular location for recreational mineral prospecting.

Identified Public Access Improvements No public access improvement has been identified for this reach.

Public Access Opportunities Opportunities are limited due to railroad on the southeast bank and private ownership on both sides of the river.


Water Quantity and Sediment Reach 1 has many tributary inflows, including Tom Bush, Moris, Matthews, Scriver, Goodeve, Quartz, Big Sheep and Deep creeks. In addition, unnamed tributaries flow into this reach. Flow data are collected at the upstream extent of this reach near the United States-Canada border (U.S. Geological Survey [USGS] Gage #12399500), including instantaneous data. Based on historical records, peak flows in this reach occur during the summer, and low flows occur during the late fall and spring. Runoff from local roadways and adjacent agricultural lands may contribute flow into the river during the wet season and periods of snowmelt.

Sediment sources throughout the reach include steep, erodible glacial outwash banks, and soils prone to erosion. Other sediment input sources likely include surface runoff and tributary inflow. Sediments are likely accumulating through the downstream end of this reach because the river is managed as a lake impounded by the Grand Coulee Dam downstream. The upstream 5 miles of this reach are regulated by upstream dams in Canada. While sediment inputs are likely reduced from upstream dams, sediments are likely accumulating at the upstream end of Lake Roosevelt. In addition, the draft of Columbia River (Lake Roosevelt) levels may cause some movement of sediment.

Water Quality In Reach 1, TMDLs are required for 4,4’-DDD, 4,4’-DDT, Alpha-BHC, dissolved oxygen, mercury, polychlorinated biphenyl (PCB), and pH. Reach 1 is also an area of concern for temperature. Reach 1 also has an approved TMDL actively implemented for total dissolved gas. Elevated total dissolved gas (TDG) levels are primarily caused by spill events at hydroelectric projects upstream of the

Appendix A




Stevens County

international border. Water passing over dam spillways becomes entrained with air bubbles, resulting in water supersaturated with dissolved gases.

Habitat Characteristics and Priority Habitat Species Presence The Columbia River in this reach supports a number of freshwater fish species, as identified in the Inventory, Analysis, and Characterization (IAC) Report. This reach contains bald eagle wintering habitat and winter range for Northwest white-tailed deer and Rocky Mountain elk, as well as priority rearing habitat for white sturgeon.

This reach extends from the Canadian border to the Northport Bridge at the edge of the Town of Northport, and includes shorelines of the river and the confluence of Big Sheep and Deep creeks. Vegetation near the upstream end of this reach on either bank is sparse due to a combination of topography and land use. The southeast has a railroad running along the entire reach, within and outside the 200-foot shoreline jurisdiction, and Northport-Waneta Road roughly parallels the tracks, also occurring within and outside of the 200-foot shoreline jurisdiction. The left bank shoreline in this reach includes some areas that have been stabilized for the protection of the railroad bed. There is a generally continuous band of riparian forested area along the left bank shoreline, which varies in width from 20 to 100 feet or more between the OHWM and the berm for the railroad.

The north bank has no roads or railroads adjacent to the river, but there is an informal trail with some segments crossing into the shoreline jurisdiction. The right bank has a more natural unbounded and mostly contiguous riparian zone along most of the reach. There are some residential developments and shoreline access points along the right bank, which interrupt the riparian habitat, and one visible formalized boat launch with a floating dock, along with several other informal or private launches. There are fewer launches visible on the left bank, aside from one associated with the campground and RV Park just upstream from Deadman’s Eddy, and a small dock near Steamboat Rock. Near the downstream end of the reach, there is some agricultural development and cleared land within the shoreline zone.

• SR 2e – Extends 4.9 miles downstream to the southeast corner of T38N_R38E_S08, just after Williams Lake Road enters State Route 25.

• SR 2f – Extends 12.3 miles downstream near the western edge of the Marcus UGA, just before the confluence of the Kettle River.

• Marcus SR 1a (UGA) – Begins at the eastern edge of the Marcus UGA and extends 1.9 miles downstream to its western edge, in the northern portion of T38N_R38E_S31 to S32. This reach includes the area through the Town of Marcus but is located outside of the town boundaries.

Characteristics

Ownership Reach 2 is about 64% public (mostly the U.S. Bureau of Reclamation) and 35% private with a small amount (less than 1%) of tribal ownership.




• NR Forest, RA-10, RA-5, RA-20, and AR-10


• North shoreline is Rural • South shoreline

− Parallel (Conservancy for 50 feet from OHWM, Rural for remaining 150 feet) − Rural

Existing Land Cover/Development Reach 2 consists mostly of forest and shrubland with very minimal development. SR 2e and 2f have the most development, including the roads, railroads, and campgrounds, including North Gorge Campground, Evans Campground, Snag Cove, and a small amount of residential development.

Geomorphic Character Description – Franklin D. Roosevelt Lake lies within a valley comprising continental glacial sediments and bedrock. Glacial units consists of continental glaciolacustrine deposits, outwash, and minor amounts of till. Mass wasting and sand dunes are also present along the lake boundaries. Bedrock occurs along the lake margins and consists mostly of a variety of rocks that include low-grade phyllite, metavolcanic rocks (Rossland Group), metacarbonate rocks of the Metaline Formation, limestone, and dolomite. River levels can fluctuate based on downstream dam operations.

Appendix A




Stevens County

Hardened Banks – 2,200 feet of artificial hardened banks exist in Reach 2 and are associated with the BNSF railroad alignment.

Flooding and Geological Hazards Flooding – Flooding is regulated by Grand Coulee Dam operations and controls located downstream in addition to reservoirs located upstream in Canada that store floodwater in accordance with the Columbia River Treaty. FEMA floodplains are mapped for the entire reach. Floodplains are generally confined retaining the shape of the channel bank with minimal spreading of flow. The Columbia River and its floodplain widens in the downstream section of SR 2f, but remain confined with minimal spreading.

Geological Hazards – Areas of unstable steep slopes (greater than 30%), landslide hazards, and erosion hazards exist along channel margins of the right and left bank throughout the reach and consist mostly of glacial outwash. Other steep areas of steep banks are comprised of glaciolacustrine deposits (SR 2a and 2c), alluvium (SR 2e and 2f), till (SR 2e), sand dunes (SR 2f), and mass wasting deposits (SR 2f). Nine mining permits are identified in the WDNR mine database along Reach 2. No known active faults exist along this reach.

Existing Public Access Multiple public accesses exist in this reach as part of Lake Roosevelt National Recreation Area. China Bend area has a boat launch. North Gorge and Evans include campgrounds, picnic areas, and boat launches. Snag Cove includes campgrounds and boat launch. Northport Flat Creek Road parallels portion of the shoreline.


Public Access Opportunities Existing public access and amenities seem adequate for this reach.


Water Quantity and Sediment Reach 2 has many tributary inflows, including Fivemile, Squaw, Onion, Rattlesnake, Crown, Ryan, Flat, Lodgepole, and China creeks. In addition, numerous unnamed tributaries flow into this reach. USGS flow data are not collected in this reach. However, flow data are collected in the Columbia River upstream in Reach 1 (USGS Gage #12399500), including instantaneous flow data. Based on historical records, peak flows in this reach occur during the summer, and low flows occur during the late fall and spring. Runoff from State Route 25, local roadways, and adjacent agricultural lands may contribute flow into the river during the wet season and periods of snowmelt.

Sediment sources throughout the reach include steep, erodible glacial outwash banks (mostly in SR 2d, 2e, and 2f), and soils prone to erosion. In addition, SR 2e and 2f have steep banks comprising alluvium.

Appendix A




Stevens County

SR 2f has banks steep banks comprised of outwash, till, and sand dunes. Sediment input sources likely include tributary inflow. Sediments are likely accumulating throughout this reach because the river is managed as a lake impounded by the Grand Coulee Dam downstream. In addition, the draft of Columbia River (Lake Roosevelt) levels may cause some movement of sediment.

Water Quality Onion Creek, a tributary entering SR 2a, is a water of concern for dissolved oxygen and pH. SR 2f has two tributaries that have a required TMDL for bacteria and one tributary that is a water of concern for dissolved oxygen. SR 2f is also a water of concern for PCB and has an implemented TMDL for dioxins. Potential sources of dioxins include a chlorine-bleaching pulp mill north of the United States-Canada border, as well as wood treaters, municipal wastewater treatment plants, release from sediments, and agricultural, industrial, and urban areas.

Habitat Characteristics and Priority Habitat Species Presence The Columbia River in this reach supports a number of freshwater fish species, as identified in the IAC Report. This reach contains bald eagle wintering habitat and golden eagle nesting territory, as well as winter range for Northwest white-tailed deer and Rocky Mountain elk. Additionally, the area from Northport downstream to China Bend is priority rearing habitat for white sturgeon. Reach 2 is characterized by sporadic patches of rural or agricultural land uses along both banks, with more development found within the shoreline jurisdiction along the left bank (looking downstream), which is paralleled by the BNSF railroad and State Route 25. Northport-Flatcreek Road runs adjacent to much of Reach 2 on the right bank (looking downstream). This reach is characterized by numerous small bays associated with the many tributary inflows, including Fivemile, Squaw, Onion, Rattlesnake, Crown, Ryan, Flat, Lodgepole, and China creeks and other unnamed creeks. There is a forested riparian zone, which in occasionally broken by residential or agricultural development on both banks. The width of the riparian zone is quite constrained in certain areas due to presence of roads and railroad berms. The majority of ownership for SR 2c through 2f are under federal ownership.

• SR 2a – This subreach begins at the southwestern edge of the Town of Northport and runs to the Little Dalles Rapids just downstream of the confluence with Onion Creek. A large expanse of undeveloped floodplain habitat exists at the upstream end of the subreach. There are several rural residential developments that have access points or docks located on the river edge. Development on the left bank is constrained by steeper sloped hills and the presence of roads and railroad.

• SR 2b – The river channel becomes constricted in this subreach, with very steep almost vertical banks. On the right bank, there is wide swath of flatter land between the top of bank and the upland road, which includes agricultural land uses and contains several residences or cabins, and a small embayment. The riparian zone is forested with trees extending to the water’s edge. The left bank is much steeper, limiting development.

• SR 2c – This subreach extends 2.1 miles downstream to T39N_R39E_S29 in the community of Marble near the confluence of Crown Creek. Due to steep bank slopes and federal land ownership within this subreach, development is concentrated outside the shoreline

Stevens County

jurisdiction. The railroad again runs along the left bank within shoreline jurisdiction. A vineyard is sited along the right bank near the end of this subreach. Riparian vegetation is generally intact and relatively wide where the shoreline slopes and presence of the railroad berm do not affect it. A Local Area of More Intense Rural Development (LAMIRD) is located on the left bank near the end of this subreach.

• SR 2d – This subreach extends 2.4 miles downstream to T38N_R38E_S01 near southern end of the China Bar and is characterized by a rural residential area that extends most of the length of the subreach. The opposite bank is relatively undeveloped. Steep slopes prevent many access opportunities to the river. The right bank is less steep and in more natural condition with intact riparian vegetation consisting of deciduous trees, shrubs, and grasses. The China Bar at the end of the subreach is a man-made vegetated island feature associated with log-booming.

• SR 2e – This subreach extends 4.9 miles downstream to the southeast corner of T38N_R38E_S08, just after Williams Lake Road enters State Route 25. The shoreline slopes are steep throughout this subreach, and there is a minimal amount of development within shoreline jurisdiction due to a combination of natural topography and land ownership transitioning to federal at the lower third of the subreach. Riparian vegetation forms a narrow band but is generally continuous on both banks. Each bank contains roads and railroads within shoreline jurisdiction that limit the width of the riparian zone.

• SR 2f – This subreach extends 12.3 miles downstream near the western edge of the Marcus UGA, just before the confluence of the Kettle River. This subreach is characterized by increasing density of development as it approaches the confluence. There are roads, a railroad, and trails located within shoreline jurisdiction on both shorelines. Shoreline slopes are much more gradual through this subreach, leading to broader floodplain-type habitat that supports agricultural development, although most of this is outside of the shoreline jurisdiction with the exception of the area at the upstream end, on the right bank where the agricultural activity extends to the top of bank. There are areas along each bank where access to the river is possible, and the reach includes a public boat launch on the right bank near the middle of the subreach, and one on the left near the downstream end, along with at least three visible informal river access points.

• Marcus SR 1a (UGA) – This subreach begins at the eastern edge of the Marcus UGA and extends 1.9 miles downstream to its western edge, and extends into the Columbia River, but does not include the opposite shoreline, which is part of SR 2f. The upstream end of the subreach is characterized by steeply sloped erosive banks, which support some riparian trees and shrub growth. Some of this vegetative growth extends over the top of bank and is contiguous with upland forested area. Marcus Island is included in this subreach, as well as a portion of the shoreline adjacent to the Town of Marcus, but is outside of the town boundaries, which do not extend to the water’s edge. Marcus Island is forested, and developed for camping. The upstream end of Marcus Island is connected to the mainland under most water conditions. The shoreline adjacent to the Town of Marcus includes the road to the boat launch located on the mainland, across from the downstream end of Marcus Island.

Stevens County

Geomorphic Character Description – Franklin D. Roosevelt Lake lies within a valley comprising continental glacial sediments and bedrock. Glacial units consists of mostly of continental glaciolacustrine deposits, outwash, and glacial drift. A minor amount of mass wasting deposits are present along the lake boundaries. Bedrock occurs along the lake margins and consists mostly of a variety of rocks that include metavolcanic rocks (Rossland Group), metacarbonate rocks of the Metaline Formation, and wacke.

River levels can fluctuate based on downstream dam operations.

Hardened Banks – There are none identified. No artificial hardened banks exist along the lake shoreline.

Flooding and Geological Hazards Flooding – Flooding is regulated by Grand Coulee Dam operations and controls located downstream in addition to reservoirs located upstream in Canada that store floodwater in accordance with the Columbia River Treaty. FEMA floodplains are mapped for the entire reach. Floodplains retain the shape of banks as the area consists of lakes with connecting river reaches and high river banks. SR 3a is a wide portion of Columbia River that includes the confluence of the Kettle River, and the floodplain is confined along the banks of the river. SR 3b through SR 3i all have confined floodplain areas along the banks of the river.

Geological Hazards – Areas of unstable steep slopes (greater than 30%), landslide hazards, and erosion-hazards exist along channel margins of the left bank throughout the reach and are mostly associated with glacial outwash and glaciolacustrine deposits throughout the reach. Minor amounts of glacial drift (SR 3a and 3b), till (SR 3c, 3e, 3h, and 3i), loess (SR 3h), and alluvium (SR 3g, 3h, and 3i) comprise these unstable steep slopes. Four mining permits (gold placer) are identified in the WDNR mine database along Reach 3. No known active faults exist along this reach.

Existing Public Access Reach 3 of the Columbia River has several formal public access sites and numerous informal ones. Kettle Falls marina is a privately managed marina. The facility has a multi-lane boat launch and floating docks. It also has picnic areas, campgrounds, swimming, and fishing opportunities. The Kettle Falls area is rich in the history of American Indians, as well as the fur trade; a park visitor center is located nearby (Recreation 2015). An informal boat launch exists south of the marina at Lions Island. Bradbury area includes beach and campground facilities. Boat launch, boat fueling facilities, and picnic areas exist in Daisy, Cloverleaf, Gifford, and Hunters shoreline. Gifford’s ferry dock connects the area with the west bank of the river at Inchelium in Ferry County. The Enterprise campground has sites near the shoreline. Kamloops Island is accessed by bridge and contains a campground. Columbia and McGuire campgrounds are located within the Spokane Reservation. An unimproved boat launch exists at Balcombs, upstream of the Columbia campground. McGuire campground is open to the public, and there are several undeveloped boat access points in camp areas downstream.

Identified Public Access Improvements Public access improvements identified in the National Park Service’s Lake Roosevelt National Recreation Area Shoreline Management Plan (Alternative B) include the following: improvement of water circulation at swim area in Kettle Falls; creation of new deep-water boat launch; day-use area and parking in Rickey Point; designating walk-in camp zone along the highway between Jerome Point and Daisy; adding low-impact (gravel) overflow parking lot in Gifford; replacing private, non-compliance docks and launches with a single, public primitive boat launch at Corkscrew; and adding a new boat-in campground at Enterprise Bar. The Spokane Reservation’s goal is to update and improve all bathroom facilities to total containment vaults within the Riverbreaks Zone. Additionally, no housing or commercial development will occur in this zone.

Public Access Opportunities Public access opportunities, including the proposed improvements, seem adequate for this reach.


Water Quantity and Sediment The tributary inflows to Reach 3 from the Stevens County side include Pingston, Hallam, Rickey, Quillisascut, Cheweka, Jennings, Magee, Stranger, Deer, Harvey, Hunter, Alder, O-Ra-Pak-En, and Castle Rock creeks and the Colville River. The tributaries from the Ferry County side include Nancy, Sherman, Roper, Martin, La Fleur, Barnaby, Little Jim, Cobbs, Hall, Stranger, Nez Perce, Falls, Coyote, Monaghan, Wilmont, Ninemile, Sixmile, Cottonwood, Threemile, and Louie creeks. In addition, numerous unnamed tributaries flow into the river along its alignment. Throughout this reach, the Columbia River is controlled by the Grand Coulee Dam and is managed as a lake. No flow data are collected along this reach or in the tributary streams; however, flow data are collected downstream at Grand Coulee Dam. Based on historical records, peak flows occur during the late spring, and low flows occur during the winter and early spring.

Sediment sources throughout the reach include steep, erodible glacial outwash banks (mostly in SR 3c, 3d, 3g, 3h and 3i), and soils prone to erosion. Sediments are likely accumulating throughout this reach because the river is managed as a lake impounded by the Grand Coulee Dam downstream. Sediment input sources likely include tributary inflow. In addition, the draft of Columbia River (Lake Roosevelt) levels may cause some movement of sediment.

Water Quality In SR 3a, a tributary called Pingston Creek requires a TDML for bacteria and is a water of concern for dissolved oxygen. An unnamed tributary to SR 3a requires a TMDL for dissolved oxygen. In SR 3b and 3c, there is a TDML in place for dioxin. Potential sources of dioxins include a chlorine-bleaching pulp mill north of the United States-Canada border, as well as wood treaters, municipal wastewater treatment plants, release from sediments, and agricultural, industrial, and urban areas. SR 3c also requires a TMDL for mercury and dissolved oxygen. SR 3e is also an area of concern for mercury.

Appendix A




Stevens County

Water quality throughout the reach is likely impacted by upstream historical industrial runoff that settles in sediment.

Habitat Characteristics and Priority Habitat Species Presence This reach is regularly used as wintering area (foraging and perching) for bald eagles. The shorelines in this reach are all under management by the National Park Service as part of the Lake Roosevelt National Recreation Area. The Columbia River in this reach supports a number of fish species, as identified in the IAC Report. It includes the portion of Lake Roosevelt within Stevens County.

• SR 3a – Includes shorelines along the confluence of the Kettle River and the area known as Kettle Falls. The shoreline consists of a narrow band of land with only sparse riparian vegetation bounded by State Route 25 on the left bank (looking downstream), running along the shoreline from just south of Marcus, and curving around to the south before the shoreline bends to the north and State Route 25 continues south. The shoreline banks are sloped and stabilized to protect the road, which minimizes the suitability for riparian vegetation grown. An informal boat launch and shoreline access area is located along this part of the shoreline just off Gold Edge Mine Road. As the left shoreline turns to the northwest, the banks become steeply sloped and erosive, with forested areas in the uplands, and little vegetation supported along the water’s edge due to the slope. There is no development within shoreline jurisdiction. Accumulations of large woody debris are present. There is some residential development within this area, located outside of the shoreline jurisdiction. Vegetation is a mixture of forested areas with mature trees, shrubs, and grasses forming large patches of forested habitat above the top of the bank.

• SR 3b – This subreach extends from just upstream of Highway 395 and railroad bridges to the downstream end of Lion’s Island at the mouth of the Colville River. There is more development, including industrial use at the Boise Cascade Mill and a designated LAMIRD zone located in the uplands along this subreach. The shoreline is steeply sloped and erosive, but riparian vegetation is present along the water’s edge and connected to upland forested patches. The vegetation is impacted by Highway 395 and railroad bridges and an electrical utility corridor. An informal boat launch is located waterward of the Boise Cascade site. The Kettle Falls marina is located to the south of the Boise Cascade site and just north of Lions Island; the facility includes boat launches, a marina, and recreational shoreline access points.

• SR 3c – There is an informal shoreline access area on the shoreline at the mouth of the Colville River, which may be used as a boat pull-up area, as well as for river access by hand-held boats. Another informal boat launch is located less than 1 mile downstream. The shoreline between these two areas is adjacent to State Route 25, and some shoreline-stabilization measures may be controlling the banks in this area because the road is less than 100 feet from the water, although there is riparian vegetation present. Downstream from the boat launch, State Route 25 moves away from the shoreline, and Rickey Point Road leads to an area of floodplain that slopes more gently toward the water with no stabilization features. There is some clearing in the uplands, with area closer to the shore providing multiple recreational access points via campsites and informal launches. Downstream of this

Stevens County

area, there is less development, and the shoreline again becomes steeper, and is adjacent to State Route 25, which is within shoreline jurisdiction. The downstream portion of this reach has a few residences and a formal boat launch, and is characterized by relatively intact forested but generally narrow riparian corridor. There are small embayments along this subreach that may provide off-channel habitat for rearing fish and more gently sloping shorelines; these areas are accessible via boat, as well as from uplands.

• SR 3d –This subreach includes a number of large and smaller coves, accessible to and used by boats, and some are accessible via uplands. There are some informal trails along the shoreline, which are accessible from roads in the uplands. The upland vegetation is forested with a mix of coniferous and deciduous trees, which extends to the water's edge along most of the subreach where the slope of the bluffs is more gradual. There are residences and other structures located along the shoreline, and in these areas, some upland forested habitat has been cleared and agricultural development is occurring outside of the shoreline jurisdiction above the top of the bluffs. The shorelines are steep bluffs in some locations, appearing highly erodible. The density of residential development is low within shoreline jurisdiction, but the uplands in this subreach are more developed than other parts of Reach 3. There is one formal boat launch within this subreach, located at the downstream end.

• SR 3e – The subreach runs along State Route 25 for a significant portion, and there is generally very little shoreline landward of the road. This subreach includes a number of large and small embayments or coves, accessible to and used by boats, and some are accessible via uplands. Vegetation between the water and road consists of patchy trees, with scrub-shrub vegetation and grasses predominating. There is agricultural land use in the uplands outside of the shoreline jurisdiction, and most of the area is cleared land or grassland with few trees. There are few residences are apparent along this subreach within the shoreline jurisdiction.

• SR 3f – The LAMIRD of Gifford is located at the upstream end of this subreach. The downstream end includes the Gifford-Inchelium Bridge. There is a wide area of floodplain between the river and more mountainous uplands, which is utilized for recreational purposes, with campgrounds, a boat launch, and marina located along the shoreline. This subreach includes smaller embayments or coves, accessible to and used by boats, and some are accessible via uplands via less formalized trails and access points. The vegetation along the shoreline is characterized by grassland scrub-shrub, with scattered deciduous trees.

• SR 3g – The subreach runs along State Route 25 for a significant portion, and there is generally very little shoreline landward of the road, and it is similar to SR 3e. Several bays and inlets related to tributaries are accessible via boat and from the uplands. The uplands outside of the shoreline jurisdiction are relatively steeply sloped and forested. Riparian vegetation includes a mix of typical riparian trees for the region, as well as coniferous species. The vegetation along the shoreline is patchy, with some areas featuring few trees and open grasslands.

• SR 3h – The shoreline is undulating and a mix of forested areas and areas of open grassland or agricultural fields. Several bays and inlets related to tributaries are accessible via boat and from the uplands. There is minimal development in the shoreline jurisdiction in this subreach due to the steeply sloped shoreline. Vegetation transitions to a drier system of pine forests

Stevens County

with some shrub-steppe vegetation along the shoreline slopes, increasingly toward the downstream end.

• SR 3i – This subreach has a number of bays and inlets associated with tributaries and small drainages from uplands. The shoreline along this subreach is moderately steep. There are a number of potential shoreline access points from U.S. Forest Service (USFS) roads and other gravel access roads and trails, as well as from the water. Vegetation consists of grassland and shrub-steppe vegetation along the shoreline, characteristic of drier climate conditions. At the end of this subreach, the shoreline vegetation is low growing grasses and shrubs, slopes are steep, and there are extensive recreational facilities associated with the Two Rivers Casino and Resort.

Columbia River (Associated Tributaries) – Deep Creek System

Stevens County

Reach Description This reach begins in divergent tributaries to Deep Creek. North Fork Deep Creek begins at the northeast corner of T37N_R40E_S13 and flows south, and South Fork Deep Creek begins at the northeast corner of T39N_R41E_S02 and flows north. Deep Creek then flows northwest to its confluence with the Columbia River at the northwest corner of T40N_R40E_S34.


Source: Google Earth

Subreaches (SRs); see Maps 12, 13, 14, and 15:

• Rocky Creek – Begins at the underpass of Rocky Creek Road and extends 0.2 mile to the confluence with South Fork Deep Creek, located in the northwest corner of T37N_R41E_S08.

• South Fork Deep Creek (SR 1a – 1c) – Begins at the northeast corner of T37N_R40E_S13 and extends 9.5 miles downstream to its confluence with Deep Creek in the northeast quarter of T38N_R41E_S05.

• North Fork Deep Creek (SR 1a and 1b) – Begins at the northeast corner of T39N_R41E_S02 and extends 6 miles downstream to its confluence with Deep Creek in the northeast quarter of T38N_R41E_S05.

• Deep Creek (SR 1a and 1b) – Begins at the confluence of North and South Fork Deep Creeks in the northeast quarter of T38N_R41E_S05 and extends 10.9 miles downstream to its confluence with the Columbia River at the northwest corner of T40N_R40E_S34.

Characteristics

Ownership The Deep Creek System is about 98% private with 2% public (Washington State Department of Natural Resources, Stevens County, and local government).




• NR Forest, RA-5, RA-10, and RA-20


• Rocky Creek: Unavailable – Not included in the existing Shoreline Master Program • Rural designation for remaining Deep Creek Systems

Existing Land Cover/Development The Deep Creek System has a lot of agricultural development; however, the shoreline consists mainly of forest, shrubland, and grasslands. The small amount of development within the shoreline occurs mostly in the mainstem SR 1a and consists of roads and residential structures.

Geomorphic Character Description – The mainstem and north and south forks of Deep Creek flow within a low-gradient, generally unconfined valley that consists of continental glacial drift along the channel and floodplain. Throughout the North and South Fork alignments, bedrock defines most of the valley walls and margins and consists of the Metaline Formation (bedded limestone), Gypsy Quartzite, and Maitlen Phyllite.

The North Fork Deep Creek and South Fork Deep Creek channel migration zones (CMZs) occupy most of the valley. Along the North Fork, no major infrastructure exists to limit migration throughout the valley bottom. In the South Fork, valley the CMZ also occupies most of the valley floor, with Aladdin Road alignment along the eastern boundary. The mainstem Deep Creek CMZ varies in width and is mostly controlled by valley width. Bedrock outcrops are limited in the upper stream extents (SR 1a). The stream valley narrows at its downstream extent and flows through a narrow, steep bedrock section (SR 1b; marine metasedimentary rocks) prior to its confluence with the Columbia River.

Hardened Banks – No hardened banks exist along Deep Creek, North Fork Deep Creek, or the South Fork Deep Creek.

Appendix A




Stevens County

Flooding and Geological Hazards Flooding – FEMA floodplains are mapped in Rocky Creek, Deep Creek, and the North and South Forks of Deep Creek. Rocky Creek’s floodplain is wide in comparison to the channel width, inundating the area surrounding the 0.2 mile of creek. There is a portion of Rocky Creek that floods a significant distance south from the channel. The floodplain of SR 1a on the South Fork of Deep Creek is moderate in width extending out from the channel banks. Aladdin Road on the west side of the creek prevents further flooding west. The floodplain for SR 1b on the South Fork primarily shows little to no flooding in this reach. This can be attributed to a small valley width and steep slopes extending from the channel. The floodplain of SR 1c on the South Fork is moderate in width with no significant areas of flood flows spreading. SR 1a on the North Fork of Deep Creek has generally moderate floodplain widths. There is a portion in the middle part of the reach where the floodplain extends significantly farther into the surrounding area. SR 1b of the North Fork starts at Deep Lake, where the floodplain is contained along the channel banks. As the river leaves Deep Lake, the floodplain is relatively narrow. The floodplain widens as the river moves downstream. Portions in the middle of SR 1b have areas where the floodplain extends farther west from the channel. SR 1a and 1b of the mainstem of Deep Creek have relatively narrow floodplains to the confluence with the Columbia River.

Geological Hazards – Areas of unstable steep slopes (greater than 30%), landslide hazards, and erosion-hazards exist along channel margins of the right and left banks throughout all the subreaches and consist mostly of glacial drift and a minor amount of glacial outwash (mainstem). Two active mining permits (one gold placer and one lead mine) are identified in the WDNR mine database along the mainstem of Deep Creek. No known active faults exist along this reach.

Existing Public Access No public access is available in this reach.


Public Access Opportunities Public access opportunities are limited due to private ownership and the sensitive nature of the shoreline in some areas.

Stevens County


Water Quantity and Sediment Tributary inflows to the North Fork Deep Creek include Hartbauer, O’Hare, McKinnon, Silver, Sherlock, Republican, Currant, Lime, and Smackout creeks. Tributaries along the South Fork Deep Creek include Kolle, Clinton, Rogers, Rocky, Kenny, Scott, Meadow, Harrier, Miller, and Little Smackout creeks. Tributary inputs to the mainstem Deep Creek include Little Johnson, Waymire, Raisio, Martella, and Todd creeks. There are numerous unnamed tributaries along all reaches. USGS flow data are not collected in the Deep Creek System; however one inactive gage (#12399600) collected data from July 1972 to January 1976 at the downstream end of SR 1b. Based on historical records, peak flows in this reach occur during the late spring, and low flows occur during the late fall and winter.

Sediment sources throughout reach include steep, erodible glacial drift banks in all subreaches of the South Fork Deep Creek and North Fork Deep Creek, and in glacial drift and outwash along the mainstem Deep Creek. In addition, the areas with soils prone to erosion that exist in all the subreaches provide a source of sediment to the system. Additional sediment input sources likely include tributary inflow.

Water Quality Deep Creek Mainstem is a water of concern for dissolved oxygen and temperature and requires a TMDL for pH. The North Fork is a water of concern for pH. The South Fork requires a TMDL for temperature. Water quality in the Deep Creek System may be impacted by agricultural, forestry, and former mineral exploration activities.

Habitat Characteristics and Priority Habitat Species Presence

• Rocky Creek – This small reach runs through a partially forested area, adjacent to land that has been cleared for agricultural or landscaping. There is no development within the shoreline jurisdiction, with the exception of vegetation management/clearing to the north and south. A small associated wetland/intermittent stream area extends the shoreline jurisdiction to the south toward the road. The Rocky Creek drainage supports regular concentrations of moose (WDFW 2015a).

• South Fork Deep Creek (SR 1a – 1c) – The South Fork Deep Creek reaches run through agricultural lands, as well as forested areas (primarily SR 1b). Aladdin Road is adjacent to or within shoreline jurisdiction in segments of each of the subreaches, with one crossing in SR 1a. Moose, Northwest white-tailed deer and Rocky Mountain elk are known to use shorelines within these subreaches, particularly during winter months.

• North Fork Deep Creek (SR 1a and 1b) – SR 1a is above Deep Lake, and SR 1b is below. SR 1a is bounded by Deep Lake Boundary road to the east and forested hillslopes to the west. There is a small area within the middle of the subreach that is forested, but the majority of North Fork Deep Creek within this subreach has no tree cover, with grasses and herbaceous groundcover dominant. SR 1a has been extensively drained and managed for livestock grazing, and there are numerous livestock trails and access points. There is associated wetland area that expands the width of the shoreline jurisdiction. SR 1a is noted for wetlands

Appendix A




Stevens County

with red-necked grebe nesting and other waterfowl foraging areas. SR 1b, south of Deep Lake, is similar in condition. Deep Lake Boundary Road crosses the creek just at the south end of Deep Lake, and runs along the western boundary. SR 1b has more adjacent tree cover along the riparian zone near the downstream end, where grazing pressure is likely less significant. Aladdin Road and Deep Lake Boundary Road meet near the confluence of North Fork Deep Creek SR 1b, and the creek is culverted under this intersection.

• Deep Creek (SR 1a and 1b) – SR 1a runs through predominantly agricultural lands, with several informal crossings and livestock watering access areas. The land has been drained for agricultural uses, and there is a minimal amount of tree cover along the riparian zone. Aladdin Road runs along SR 1a with some segments located within shoreline jurisdiction, and one crossing near the end of the subreach, as the valley becomes narrower and the forested areas along the banks become more consistent and contiguous to upland forested habitat. SR 1b is a transition from the wider floodplain valley to a more narrow and constrained channel and forested habitat as it approaches the confluence with the Columbia River. Bald eagles and Northwest white-tailed deer are noted to use both reaches for wintering habitat.

• Big Sheep Creek:

− Rural − Conservancy for public lands

• Little Sheep Creek

− Conservancy

Existing Land Cover/Development The Big Sheep Creek is mostly undeveloped with forest extending to the shoreline. The area surrounding Little Sheep Creek is mostly forested with a moderate amount of agriculture; however, most of the development within the reach is associated with roads and structures. Additionally, Sheep Creek Hydro operates in this system.

Geomorphic Character Description – At its upstream extent (SR 1b), Big Sheep Creek has a meandering channel planform and flows within a low-gradient valley that consists of continental glacial drift. In its lower extent, the valley is confined and steep, and flows through glacial outwash and bedrock where Sheep Creek Falls are located. Little Sheep Creek is a tributary to Big Sheep Creek. Little Sheep Creek flows within a narrow valley consisting mostly of continental glacial outwash. The channel is confined by Highway 25, which is located adjacent to the stream throughout its valley.

In its upstream extent (SR 1b), Big Sheep Creek has a wide CMZ. The channel is actively migrating throughout its unconfined valley. Limited infrastructure exists to limit this migration. In its lower extent (below the confluence with Little Sheep Creek), the CMZ is narrower, and the channel migration potential is low. Little Sheep Creek has a narrow CMZ due to its confined valley and the alignment of Highway 25.

Appendix A




Stevens County

Hardened Banks – No hardened banks exist along Big Sheep Creek or Little Sheep Creek.

Flooding and Geological Hazards Flooding – FEMA floodplains are mapped throughout the Little Sheep and Big Sheep reaches. Little Sheep Reach 1 has a relatively narrow floodplain that expands onto Highway 25/Little Sheep Creek Road in some locations. SR 1a has the widest floodplain areas of any of the subreaches, extending a significant distance into the forest along the shoreline. The floodplain narrows again in SR 1b as Big Sheep Creek continues to its confluence with Little Sheep Creek. SR 1c of Big Sheep Creek is also narrow, and there is a portion of the reach in which FEMA floodplains are not established. The floodplain widens as SR 1c reaches the Columbia River.

Geological Hazards – Areas of unstable steep slopes (greater than 30%), landslide hazards, and erosion-hazard exist along channel margins of the right and left banks throughout the reach and consist mostly of glacial outwash throughout Big Sheep Creek and Little Sheep Creek, with the exception of Big Sheep Creek SR 1a. Big Sheep Creek also has steep banks comprising drift (SR 1a and 1b), till (SR 1b and 1c), and a minor amount of alluvium (SR 1c). Three gold mines are identified in the WDNR mine database along the mainstem of Sheep Creek. One mine is located along Little Sheep Creek. No known active faults exist along this reach.

Existing Public Access Sheep Creek campground includes campground and trail. Big Sheep Creek is a popular location for recreational mineral prospecting, especially between 9-Mile Bridge and the Upper Falls.

Identified Public Access Improvements No new public access has been identified.

Public Access Opportunities Opportunities are limited due to private ownership of shoreland.


Water Quantity and Sediment Tributary inputs to Little Sheep Creek include Boundary Creek and multiple unnamed tributaries. Tributary inputs to Big Sheep Creek include Corral, Gold, and Turner creeks and multiple unnamed tributaries. Intermittent flow data is available near the mouth of Big Sheep Creek (USGS Gage # 12400500). Historical records indicate that peak flows occur during the late spring, and low flows occur during the early fall and late winter.

Sediment sources throughout reach include steep, erodible glacial outwash, drift, till and alluvium banks in all subreaches of the Big Sheep Creek and Little Sheep Creek. In addition, the areas with soils prone to erosion that exist in all the subreaches provide a source of sediment to the system. Additional sediment input sources likely include tributary inflow. Depositional features (bars) exist in Big Sheep Creek (SR 1a) where the channel has a meandering channel pattern.

Appendix A




Stevens County

Water Quality Big Sheep Creek SR 1c is a water of concern for pH. Water quality is monitored at Department of Ecology Ambient Monitoring Station #61D070 near the mouth of the creek.

Habitat Characteristics and Priority Habitat Species Presence

• Little Sheep Creek, from the Canadian border to the confluence with Big Sheep Creek, is mostly forested areas mixed with agricultural development; however, most of the development within the reach is associated with roads (State Route 25), structures, and some informal private crossings. Some upland forest practices (clearing) may present habitat impacts within shoreline jurisdiction through erosion and lack of contiguous forested upland habitat.

• The Big Sheep Creek subreaches include minimal development, with forested riparian habitat extending almost the entire width of the shoreline jurisdiction; however, there is a small hydropower facility on Big Sheep Creek at Sheep Creek Falls. There are several scattered residential areas located primarily in SR 1c, which also includes a visible potential diversion upstream of the waterfall. There is a recreation area near the confluence with Little Sheep Creek, and there appear to be informal access points near the confluence. All of the Big Sheep Creek subreaches include habitat noted for wintering presence of bald eagle, Northwest white-tailed deer, and lynx. Additionally, Big Sheep Creek contains priority spawning and rearing habitat for interior redband trout below Sheep Creek Falls.

Ecological Functions Analysis Little Sheep Creek Reach 1 Level of Existing Function Little Sheep Creek is designated as Functioning, with some impacts at the upstream ends associated with agriculture.


• Roads • Rural residential development • Agricultural land use

Recreational use:

• Minimal


• Where possible, through voluntary landowner participation, restore and enhance wetland or forested riparian habitat and functions


Appendix A




Stevens County

• Protect intact riparian forested habitat throughout this reach

Big Sheep Creek (SR 1a – 1c) Level of Existing Function Big Sheep subreaches are all designated as Partially Functioning due to minimal development stressors, but the presence of the hydropower facility and recreational mineral prospecting have some impact on existing level of function.


• Hydropower facility

Recreational use:

• Some access more likely to occur within SR 1c • Dredging and sluicing activities associated with recreational mineral prospecting


• Where possible, through voluntary landowner participation, restore floodplain vegetation around mouth of Big Sheep Creek


• Protect intact riparian forested habitat throughout this reach

Appendix A



Columbia River (Associated Tributaries) – Onion Creek

Stevens County

Reach Description This reach begins at the southwest corner of T38N_R39E_S01 near Hawks Road and extends 4.9 miles downstream to its confluence with the Columbia River in the northwest corner of T39N_R39E_S23.


Source: https://fortress.wa.gov/ecy/coastalatlas/UICoastalAtlas/Tools/ShorePhotos.aspx, Google Earth

Subreaches (SRs); see Map 19: There are no subreaches located in the Onion Creek Reach.

Characteristics

Ownership Onion Creek is about 85% private and 15% public (WDNR).




• NR Forest and RA-10


• Rural

Existing Land Cover/Development Onion Creek is has agricultural development in the upper and lower portions of the reach, with forest covering the remaining area. Development within the shoreline is mainly roads.

Appendix A




Stevens County

Geomorphic Character Description – Onion Creek flows within a somewhat confined valley that consists of mostly till and glaciolacustrine deposits. Bedrock valley margins include acidic felsic rocks of the Spirit Pluton, bedded dolomite of the Metaline Formation, and Ledbedder Slate.

The CMZ is generally narrow and is limited by the width of the valley and steep valley walls. Limited infrastructure is present to limit the potential channel migration.

Hardened Banks – There are none identified. No artificial hardened banks exist along Onion Creek.

Flooding and Geological Hazards Flooding – FEMA floodplains are established in small areas of Onion Creek, specifically near its crossing with Onion Creek Road near the lower portion of the reach, as well as near the pasture areas in the upstream area of the reach. The lower portion is relatively confined and the upper portion is moderate in width.

Geological Hazards – Areas of unstable steep slopes (greater than 30%), landslide hazards, and erosion-hazards exist along channel margins of the right and left banks throughout the reach. Unstable steep slope landslide hazard areas are associated with alluvium, glaciolacustrine, and till deposits. No active mines exist along Onion Creek. No known active faults exist along this reach.

Existing Public Access Informal public access is available on public lands. Fishing opportunities are available near the railroad.


Public Access Opportunities There are limited public access opportunities due to forested land. However, some opportunities exist on public land.


Water Quantity and Sediment Inputs to Onion Creek include numerous unnamed tributaries. USGS flow data are not collected in this reach. Runoff from local roads and agricultural lands may contribute flow into the river during the wet season and during periods of snowmelt.

Sediment sources throughout reach include steep, erodible glacial till and alluvium banks with a minor amount of glacial outwash banks throughout the reach. In addition, there are areas with soils prone to erosion that exist throughout the reach and provide a source of sediment to the system. Additional sediment input sources likely include tributary inflow.

Appendix A




Stevens County

Water Quality An unnamed tributary to Onion Creek is listed as a water of concern and another waterbody requires a TMDL for dissolved oxygen. Onion Creek is a water of concern for pH and requires a TMDL for bacteria and dissolved oxygen. Water quality in this reach is monitored at the mouth of Onion Creek (Department of Ecology Ambient Monitoring Station # 61C070).

Habitat Characteristics and Priority Habitat Species Presence There is minimal development within this reach, and the riparian areas are mostly forested, with habitat contiguous to the surrounding uplands. Agricultural development exists within the upper and lower portions of the reach. Development within the shoreline is mainly associated with Clugston Creek/Onion Creek road, which has segments within and outside of shoreline jurisdiction and crosses Onion Creek about halfway through the reach. At the mouth of Onion Creek, there is some land clearing and agricultural access, with the creek being crossed by State Route 25 and BNSF railroad track bridges. Wintering habitat for bald eagles and Northwest white-tailed deer is noted for Onion Creek.


Level of Existing Function Onion Creek is designated as Functioning due to low levels of development or encroachments, although the area near the mouth is Partially Functioning.


• Minimal, primarily associated with roads and railroad • Undersized culverts

Recreational use:

• Minimal public access available


• Where possible, through voluntary landowner participation, restore floodplain habitat and vegetation near confluence with Columbia River


• Protect intact riparian forested habitat • Protect upland forested habitat • Restore fish passage by replacing undersized culverts
