Hastings County Lake Quality

Ontario, 66 lakes, measured by Ontario MECP

Hastings County in Ontario carries 66 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 66 monitored lakes in Hastings 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.
