Mackinac County Lake Quality

Michigan, 55 lakes, measured by EGLE

Mackinac County in Michigan carries 55 monitored lakes — one of the lake-richer counties in our dataset. Coverage that dense usually reflects active lake-association sampling alongside state-agency monitoring. The 55 monitored lakes in Mackinac 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.
