GOAL + OBJECTIVEThe USGS Habitat Needs Assessment (HNA) summaryconcludes that habitats throughout all Mississippi Riverreaches are currently degraded and are expected to getworse in the years ahead. BARGE TRAFFIC POLLUTION HISTORICAL RIVER RiverFIRSTA paradigm shift in our approach to urban watersis imperative if we expect to reverse this trend ofenvironmental degradation. Furthermore, the USGSpoints out that habitat needs along the MississippiRiver are expected to nearly double by 2050 if noaction is taken. ARMORED SHORELINE2
ENVIRONMENTAL POOL PLANS Prepared By: FISH AND WILDLIFE WORK GROUP : RIVER RESOURCES FORUM (USACE, MN DNR, IA DNR, WI DNR, US FISH & WILDLIFE SERVICES, NPS) ISLAND CREATION IN POOL 3CURRENT RIVER CONDITION- Lack of Vegetative / Terestrial Habitat- Minimal Public access to River shore- Existing wetlands are becoming less productive due to sedimentation- Loss of islands caused water flow to become sheet flow which reduce flow and diversity of aquatic habitatBENEFITS OF ISLAND CREATION- Improvements to terrestrial habitat- Restore native vegetation along stream banks- Revert river to pre-lock and dam aquatic habitat of the pools- Islands provide habitat for terrestrial species- Shorelines of islands provide nesting sites for aquatic species The Environmental Pool Plans establish- Provide sheltered beach for public acces to rivers edge desired habitat conditions and identify actions to reverse the trend of reduced ecological integrity.DESIRED FUTURE HABITAT CONDITIONS Implementation of the Environmental Pool Plans- Opportunities exist for improving aquatic habitat above St. Anthony Falls by restoring historic rapids, improving connectivity of a small will begin the steps necessary to reach a more stream and side channel, and building a string of small islands sustainable Mississippi River ecosystem. from Boom Island park upstream to the head of navigation. ENVIRONMENTAL POOL PLAN : PAGE II- The adjacent graph shows that we are in a critical time period for actionSTATE RULE 6115.0191 : Subpart 6Allows fill in a public water is allowed for fish and wildlife habitat improvement. The specific language of the subpart is:Subp. 6. Fish and wildlife habitat. Filling to restore or improve fish and wildlife habitat, except for filling in designated trout streams,shall be permitted provided plans are submitted showing the nature and degree of habitat to be benefited, and the project will not createother adverse effects such as flooding, erosion, sedimentation, or navigational obstructions. 3
