Project Details

PROJECT IN CONTEXT:

The Dowagiac River Restoration Project is part of a larger restoration effort within the St.

Joseph River Watershed, of which the Dowagiac River Watershed (DRW) is a sub-watershed.

With the removal of the Pucker Street Dam in 2021, 7.75 miles south of this project, 159 miles

of the Dowagiac River and its tributaries within the greater St. Joseph River Watershed were

reconnected, allowing for movement of potamodromous fish migrating from Lake Michigan and

other fish above the dam once again. In its current form, the Dowagiac River is a heavily

manipulated system with a straightened planform, homogeneous sandy bottom, and levees

preventing frequent lateral connection with the floodplain. The Pokagon Band Department of

Natural Resources (2019) and Michigan DNR (Wesley and Duffy 2003) assessments have found

that the River has consistently marginal habitat except for a few areas. According to Wesley and

Duffy 2003, “the Dowagiac River has the potential to provide spawning habitat for

potamodromous trout, salmon, and lake sturgeon - provided that meander restoration occurs.”

Further, reducing turbidity and sedimentation within the system is especially important to cool

and coldwater systems because coldwater fishes are particularly susceptible to their impacts

(Kaufmann and Hughes 2006).

GOALS OF THE EFFORT:

To restore historic meanders to the Dowagiac River and provide a more resilient and functional

hydrologic system that can support a healthy fishery through in-stream habitat enhancements and

reconnection to the riverine floodplains.

RESULTS:

The first phase of the project was able to restore two historic meander bends to the Dowagiac

River through the movement of over 65,000 cubic yards of soil and the installation of 4,200 face

feet of fabric encapsulated soil lifts with stone toe and live stakes as well as over 450 large wood

pieces within floodplain jacks and cribwalls for stabilization and creation of in-stream habitat.

Following the groundwork restoration in this phase, native vegetation including shrubs, trees,

and seed were planted (Figure 1 and Appendix 1).
