Osage County Lake Quality

Oklahoma, 21 lakes, measured by Oklahoma DEQ

There are 21 monitored lakes in Osage County. The mix is varied enough that the county-level average tells you the broad strokes, not the choose-this-cabin specifics. 3 of those lakes carry recent nutrient and algae readings. The county-level summary describes that subset, not every water body listed. Phosphorus and algae readings vary widely across Osage 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 Sandy Beach Lake.
