Recreation use not supported

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. Marie Lake is listed impaired under Clean Water Act §303(d) (IR 4A) for nutrients (phosphorus, nitrogen). Check local advisories before you swim.

Whether Marie 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 Targeted Survey on July 8, 2019 caught 32.43 largemouth bass per hour of electrofishing at Marie Lake. Length samples in the latest survey that recorded them ran 5–19 inches.

A DNR fisheries survey reports fish abundance and catch rates, not water quality. LakeQuality shows Marie Lake’s water-quality measurements separately, and the water-quality trend over 6 years of monitoring is improving. Catch rate is not a swim clearance and is not a weekly bite report.

From the 2019-07-08 survey

A survey of nearshore fish species was conducted on Marie Lake from July 8 - 11, 2019 by Sauk Rapids Area staff. Ten sampling sites were evenly spaced around the shoreline and each site was sampled by backpack electrofishing and seining, except one site where dense vegetation prevented seining. Nearshore sampling…
