Oklahoma, 4 lakes, measured by Oklahoma DEQ

The county-level summary describes that subset, not every water body listed. Phosphorus and algae readings vary widely across Delaware County; the per-lake pages below carry the numbers.
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 Grand Lake.
