Ontonagon County Lake Quality

Michigan, 14 lakes, measured by EGLE

Ontonagon County holds 14 monitored lakes. With a sample that small the county-level summary describes those specific waters, not necessarily every water body in the county. The 14 monitored lakes in Ontonagon County carry whatever clarity, phosphorus, and chlorophyll-a readings EGLE 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.
