Lake Medina has been added to the list of water bodies included in the 2012 Secchi Dip-In Program and the Citizen Lake Awareness and Monitoring Program (CLAM). These Citizen Science programs are designed to get volunteers involved in water quality monitoring by contributing to a data-set that improves our understanding of the water quality both locally in Ohio and across the United States and Canada.
Formerly the water supply for the City of Medina, the 125 acre lake is now leased by the Medina County Park District. A man-made reservoir, Lake Medina is located between Granger Road and State Route 18 at the confluence of the North Branch and West Branch of the Rocky River. Water clarity in the lake was very good on the day of sampling with visibility down to over nine feet. Other parameters measured during these assessments included: pH, temperature, conductivity, and water color analysis.

For those of you more interested in wetting a line rather than a probe, Lake Medina is also open to fishing and is stocked annually. Fish present in the lake include: both Black and White Crappie; Channel Catfish; Largemouth Bass; Bluegill, Green, Warmouth, and Pumpkinseed Sunfish; Yellow Perch; and yes, Walleye.
The Secchi Dip-In provides a single snap-shot in time for lakes, ponds, and streams; but the CLAM assessment is ideally conducted twice a month from May through October. These types of assessments provide a barometer of the health of our waters and help agencies like the Rocky River Watershed Council, Ohio Lake Management Society, and Ohio EPA document changes in water quality over time. Measurements such as water clarity can indicate the amount of sediment present and/or indirectly gauge the amount of nutrients present. Excessive algal growth can cloud waters as can suspended soil particles carried downstream. The Rocky River Watershed Council is looking for volunteers to continue the monitoring of lakes within the watershed, and is hoping to provide training for CLAM assessment methods in the near future. Additionally, the Rocky River Watershed Council hopes to add Brunswick Lake to the list of sampling sites in the Rocky River watershed.
