The F is nutrients and algae, not a swimming clearance. Quivera Little Salt Marsh Lake is listed impaired under Clean Water Act §303(d) (IR 4A) for nutrients (phosphorus, nitrogen), pH / acidity, salinity / chlorides, sediment / turbidity. Check local advisories before you swim.
Water Quality Grade: F (Algae-prone)
Very murky, less than 0.9 ft of visibility. Phosphorus 280 µg/L. Chlorophyll-a 83 µg/L. TSI 79. The letter is not a swimming clearance.

Lake Size & Watershed
Size, shoreline, and watershed area from HydroLAKES (HydroSHEDS). Mean depth here is modelled, not surveyed — HydroLAKES v1.0 estimates lake depth from surrounding terrain rather than from soundings. Treat it as an approximation, and prefer a state bathymetric survey where one exists.
