Ecologists at the DuPage Forest Preserve District’s Urban Stream Research Center successfully propagated and released 495 freshwater mussels in three different watersheds in 2021.
Freshwater mussels are the most imperiled animal in the world, and their presence is a strong indication of a healthy river system. As filter feeders, one adult mussel can filter up to 20 gallons of water a day, and their survival is vital to the ongoing health of a river ecosystem. The Urban Stream Research Center (USRC) has been propagating and releasing freshwater mussels since 2012.
The USRC cultivated 78 sub-adult giant floaters (Pyganodon grandis) and released them beneath floating wetlands along a section of the Chicago River in 2021, in collaboration with Urban Rivers, a nonprofit organization.

Their flagship project, called Wild Mile, calls for creating a milelong floating park on the North Branch of the Chicago River by constructing floating wetlands between Chicago and North avenues on the east side of Goose Island.
As a part of this habitat enrichment project, Urban Rivers is using the ecosystem services of freshwater mussels for their floating wetlands. USRC ecologists will continue this great partnership in 2022 by propagating more sub-adult mussels for Urban Rivers.

In fall 2021, 51 sub-adult plain pocketbook (Lampsilis cardium) propagated at USRC were released into the Fox River watershed in partnership with the Forest Preserve District of Kane County (FPDKC).

This partnership to augment freshwater mussel populations in FPDKC streams will continue into 2022. Currently, the USRC is rearing juvenile elktoe (Alasmidonta marginata), fluted-shell (Lasmigona costata), and fat mucket (Lampsilis siliquoidea) for release into FPDKC streams once the individuals are big enough.

Des Plaines River Watershed
USRC ecologists propagated 366 giant floaters (Pyganodon grandis) and released them into the streambed of the recently restored Spring Brook at St. James Farm Forest Preserve, which is part of the Des Plaines River watershed.

Before restoration efforts, freshwater mussels were almost nonexistent in this stretch of stream. With habitat now suitable for freshwater mussels to survive and thrive, more species will be propagated to continue augmenting this head-start mussel population for years to come.

How It All Started
The Forest Preserve District’s Urban Stream Research Center is one of the few facilities in the country propagating freshwater mussels. Since opening in 2012, the Urban Stream Research Center has successfully propagated more than 25,000 mussels that have been released into local waterways.
The Urban Stream Research Center is located at Blackwell Forest Preserve in Warrenville where Springbrook Creek enters the West Branch DuPage River. The building was funded by a grant from the National Oceanic and Atmospheric Administration. It is the result of a partnership between DuPage Stormwater Management and the Forest Preserve District of DuPage County.
The Forest Preserve District manages more than 1,100 acres of aquatic habitats, including lakes, streams and rivers. The Urban Stream Research Center also serves as a field research station, partnering with local conservation groups, universities and other institutions on collaborative applied research in aquatic conservation that seeks solutions to problems facing urban rivers and streams.
