D'Autray County Lake Quality
Québec, 14 lakes, measured by MELCCFP
D'Autray County holds 14 monitored lakes. With a sample that small the county-level summary describes those specific waters, not necessarily every water body in the county. The 14 monitored lakes in D'Autray 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.
