Guysborough County Lake Quality

Nova Scotia, 105 lakes, measured by NSECC

Guysborough County has 105 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 105 monitored lakes in Guysborough County carry whatever clarity, phosphorus, and chlorophyll-a readings NSECC 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.
