The Ohio Division of Watercraft's Scenic Rivers Program is holding several workshops in the northwest Ohio area in order to recruit and train volunteers to assist in water quality monitoring on the Maumee and Sandusky rivers. These volunteers will learn how to seine and ID the tiny aquatic insect life in the rivers, and see how the type, number and diversity of these macro-invertebrates serve as key indicators of water quality. The first workshop is Saturday (July 14) from 10-11:30 a.m. and meets at Farnsworth Metropark, in the Roche de Bout parking lot. Wear closed-toe shoes and be prepared to wade in the Maumee. The August classes will focus on the Sandusky River and meet on Aug. 18, first from 10:30-11:30 at the public fishing access parking lot at Indian Mill Park in Upper Sandusky, and then from 1-2:30 p.m. in the canoe launch parking lot at Wolf Creek Sandusky County Park near Fremont. Again, dress for wading.
