Providing habitat to more than 80 species of fish and 26 species of freshwater
mussels, French Creek is among the most biologically diverse streams in the northeastern United States. Environmental concerns about the creek's water quality have been raised since at least the 1990s. Improvements to sewage treatment plants in Meadville, Cambridge Springs, and Saegertown have helped reduce the amount of
chlorine and other chemicals entering the stream. Farm and highway runoff, malfunctioning septic systems, erosion, sedimentation, invasive species, and damaged
riparian zones are other problems affecting the creek. The French Creek Project, organized in 1995, sponsors French Creek music festivals, ecology tours, and watershed classes for the public. ==Awards==
