Cochrane District County Lake Quality

Ontario, 128 lakes, measured by Ontario MECP

Cochrane District County in Ontario carries 128 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 128 monitored lakes in Cochrane District County carry whatever clarity, phosphorus, and chlorophyll-a readings Ontario MECP 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.
