The outdoor recreation season is getting into full swing and, for many, the summer fun will center around the Huron River. The Annual Huron River Day celebration will be held Sunday, May 19th at Island Park. As festivity preparations continue, we wanted to get an update on the health of the river and its watershed. New grades put it at about a C+. There are challenges, there are victories and there is more work to be done. WEMU's David Fair checked in with Huron River Watershed Council executive director Rebecca Esselman for the latest.
