Jackson Parish County Lake Quality

Jackson Parish County holds 1 monitored lake. With a sample that small the county-level summary describes those specific waters, not necessarily every water body in the county. Every one of those lake carries recent nutrient and algae readings, so the county-level summary covers the full set rather than a monitored subset. The county's readings sit in the middle of the Louisiana range, with one or two lakes pulling the average up or down depending on year.

The county's lakes lean shallow, which makes the readings sensitive to wind, sediment-resuspension, and any nutrient inputs from the watershed. The cleanest measured lake is Chatham Lake.
