Les Pays-d'en-Haut County Lake Quality
Québec, 109 lakes, measured by MELCCFP
Les Pays-d'en-Haut County has 109 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 109 monitored lakes in Les Pays-d'en-Haut County carry whatever clarity, phosphorus, and chlorophyll-a readings MELCCFP 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.
