Mahoning County Lake Quality

Ohio, 11 lakes, measured by Ohio EPA

Mahoning County holds 11 monitored lakes. With a sample that small the county-level summary describes those specific waters, not necessarily every water body in the county. The 11 monitored lakes in Mahoning County carry whatever clarity, phosphorus, and chlorophyll-a readings Ohio EPA has published, shown as reported.

Most of the county's monitored lakes are shallow, under 50 feet, which means wind keeps the water column mixed all summer and sediment-bound phosphorus releases back into the surface layer whenever the bottom is disturbed.
