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 Cramer Lake is safe to swim in today is a call for the Minnesota Pollution Control Agency and the Minnesota DNR and the county health department, who post current advisories. LakeQuality does not issue swimming clearances.

DNR fisheries survey

Minnesota DNR's Standard Survey on June 25, 2019 caught 8.00 northern pike per gill net at Cramer Lake. Length samples in the latest survey that recorded them ran 2–37 inches.

A DNR fisheries survey reports fish abundance and catch rates, not water quality. LakeQuality shows Cramer Lake’s water-quality measurements separately, and the water-quality trend over 3 years of monitoring is declining. Catch rate is not a swim clearance and is not a weekly bite report.
