Saline County Lake Quality

Saline County has 12 monitored lakes — a thin enough sample that one or two stressed lakes can move the county average noticeably. Use the per-lake pages below for what actually matters. 1 of those lake carry recent nutrient and algae readings. The county-level summary describes that subset, not every water body listed. On average, Saline County lakes carry some of the lowest phosphorus and chlorophyll-a readings in Arkansas, with clear summer transparency across most monitored basins.

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. Lake Winona has the lowest nutrient and algae readings in the county.
