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. Devil'S Lake is listed impaired under Clean Water Act §303(d) (IR 5) for algal growth, oxygen depletion (low DO), pathogens (E. coli, fecal). Check local advisories before you swim.
Whether Devil'S Lake is safe to swim in today is a call for the Oregon Department of Environmental Quality and the county health department, who post current advisories. LakeQuality does not issue swimming clearances.
