The five most imperiled and vulnerable species in the United States are all freshwater aquatic organisms, and freshwater mussels are at the top of the list.
Mussels play a vital, irreplaceable role in the overall health of aquatic habitats. They act as filter feeders by taking in large amounts of water, filtering out bacteria, algae, detritus, and pollutants before passing clean water back into the lake or river. One small adult mussel can filter more than 20 gallons of water in one day.
The Forest Preserve District of DuPage County manages more than 1,000 acres of aquatic habitats, including lakes, wetlands, streams, and rivers flowing through DuPage forest preserves.
Since its first release in 2016, the District has propagated, reared, and released just under 29,000 sub-adult mussels of six species into watersheds of the DuPage River, Fox River, Lake Michigan, and the Des Plaines River to boost low natural populations.
The Urban Stream Research Center, which was funded by a grant from the National Oceanic and Atmospheric Administration and in partnership with DuPage County Stormwater Management, opened in 2012.
