Sudbury District County Lake Quality

Ontario, 260 lakes, measured by Ontario MECP

Sudbury District County has 260 monitored lakes, enough that within-county variation matters as much as the county average. Some are deep glacial basins, others are shallow agricultural-watershed waters, and the measurements reflect that mix. The 260 monitored lakes in Sudbury 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.
