About the event

The Lower Olentangy River is a 32-mile section of the Olentangy River that begins at the Delaware Dam in Delaware County and runs south to the confluence with the Scioto River in the City of Columbus.

This freshwater ecoregion is considered to be globally outstanding because of the sheer numbers of aquatic species found within it: 206 native fish species, 122 unionid mussel species, 49 species of crayfish, and 60 native species of amphibians and aquatic reptiles (Abell, Olson, Dinerstein, et al., 2000).

The great diversity in this region is the result of both upland and lowland habitats, and the presence of both glaciated and unglaciated stream systems. Approximately 12% of the fish, 14% of the mussels, 47% of crayfish, and 5% of the reptiles and amphibians are restricted to this ecoregion and found nowhere else.

About FLOW: Friends of the Lower Olentangy Watershed was formed as a community non-profit in 1997. Our mission is to keep the Olentangy River and its tributaries clean and safe for all to enjoy, through public education, volunteer activities, and coordination with local decision-makers. We sponsor invasive species removals, river cleanups, tree plantings, and a stream quality monitoring program. We are also working on a comprehensive green space plan - including a GIS database, which will provide an important tool for education, regional planning, and sustainability research.
