BigWalnutCreek is a large watershed which exists within four different counties and has a drainage area of 557 square miles.
The Friends of BigWalnutCreek (FoBWC) are a local watershed group which advocates for BigWalnutCreek in that part of its watershed from Hoover Dam south to the confluence of BigWalnut with Blacklick and Alum Creeks at Three Creeks Park in SE Franklin County.
The Friends of BigWalnut have strongly encouraged the OEPA to designate specific guidelines to the City of Columbus to maintain current flow conditions if the RWL is initiated and that higher quality water be released to compensate for the lower flow regime.
BigWalnutCreek near Pizzuro Park in Gahanna is in "excellent" condition.
Not only was the project part of their stream ecology unit, their findings will help a number of groups, including the Friends of BigWalnut and the Franklin County Soil and Water Conservation District, to monitor local water quality.
This is the first time Hoggarth and her students have studied the creek in the fall.
