Outdoor Restoration.
Best Management Practices:
Barrier removal
Fieldstone placement (450 cubic
yards)
Tree removals
Grading and slope stabilization
(topsoil placement & 500 sq. yds.
mulch blanket)
Sediment removal (2,000 cy)
Excavation of up to 14,000 cy
Whole tree revetments (1,150
lineal feet)
Grass, tree & shrub plantings
Project Benefits:
Connected ecology of over 7
miles of Wheeler Creek to the
Manistee River.
Natural movement of woody
debris, substrate, aquatic insects,
and fish throughout Wheeler
Creek.
Eliminate scouring of the
streambed downstream of the
former dam site.
Eliminate risk of dam failure due
to structural deficiencies.

The Manistee River is a State designated Natural River and federally
designated Wild & Scenic River. Portions of the Manistee River are Blue
Ribbon Trout Stream and it provides a popular fishery for steelhead, salmon,
brook and brown trout. Wheeler Creek is one of the coldest, high quality
tributaries to the Manistee and it is dominated by a self-sustaining
population of brook trout. Wheeler Creek is heavily wooded and runs
through large tracts of public lands with natural springs in its headwaters and
near the confluence with the mainstem.
The main problem with Wheeler Creek was that it had an aging and
deteriorating dam near its confluence with the Manistee River. A dam was
built in this location by John Wheeler in 1867 and was the site of the first
sawmill in the county. A couple fires occurred and a concrete dam was built
in the 1940’s to provide power to nearby homes. The 20’ high concrete
spillway and barrier were cracking and starting to break apart, and the stop
logs were in poor shape. CRA and partners worked together to drawdown
the ponds and remove the dam in the fall of 2009. Channel restoration was
completed in three phases: 2 months, 6 months and final phase 2.5 years
after dam removal. This phased approach allowed the river channel to create
a natural sinuosity, with us stabilizing it once formed. Now with the dam
successfully removed, the stream channel is restored and the risk of
structural failure from high water events is no longer an issue.

Wheeler Creek Dam Removal & Stream Restoration Photos
Wheeler Creek spillway before … spillway had to be broken up, wasn’t feasible to partially remove
Looking upstream at dam site after removal in Nov 2009… & in August 2012 after slopes pulled back &
revegetation.
Before – steep banks were caving in. After – pull back banks and place fieldstone.
August 2010 after revegetation. Original stumps indicated original topography.
Largest impoundment immediately upstream of dam site (note light pole in center of photo)
October 2009 – draw down at 2’ December 2009 – after dam removal
January 2010 – Slopes pulled back & stabilized … & August 2010 (note light pole in center of photo)
Before After dam removal & slope work
March 2012 – some banks were still eroding After – July 2013 whole trees were used
Root wad toe provides habitat & diversity versus solely using rock
May 2012 July 2013 - after
Whole tree revetments Woody debris work where needed
Banks were steep and floodplain was limited.
Final phase in May 2012 involved recreating the river corridor, stabilizing banks and planting work.
Up to 15,000 yards of material has been moved over the project period.
720 plantings of dogwood, ninebark, red maple, red oak, white spruce, white pine, white cedar & willow
