Swimming Safety
Grade onlyAlgae risk
Based on clarity and algae grades from past sampling — we do not hold live water temperature and a current cyanobacteria reading for this lake. Check your state or county health department before you swim.
The F is nutrients and algae, not a swimming clearance. Check local advisories before you swim.
Water Quality Grade: F (Algae-prone)
Very murky, less than 2.8 ft of visibility. Phosphorus 50 µg/L. Chlorophyll-a 35 µg/L. TSI 63. The letter is not a swimming clearance.
