Swimming conditions
Readings onlyLimited data
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. Metacomet Lake is listed impaired under Clean Water Act §303(d) (IR 5) for algal growth, nuisance exotic species, oxygen depletion (low DO). Check local advisories before you swim.
Whether Metacomet Lake is safe to swim in today is a call for the Massachusetts Department of Environmental Protection and the county health department, who post current advisories. LakeQuality does not issue swimming clearances.
