Algae risk

Based on clarity and algae readings from past sampling — there is no live water temperature and a current cyanobacteria reading for this lake. Check your state or county health department before you swim.

Nutrient and algae readings are not a swimming clearance. Check local advisories before you swim.

Whether Bois D Arc Lake is safe to swim in today is a call for the Arkansas Division of Environmental Quality and the county health department, who post current advisories. LakeQuality does not issue swimming clearances.
