Lake Kohlmier Temporarily Closed

OWATONNA, Minn., Jul. 2, 2025 – Lake Kohlmier is temporarily closed due to higher than normal bacteria test results today. This is a precautionary measure for public safety.

The lake will remain closed until test results return to the recommended range per Minnesota Department of Health guidelines. Staff will continue to conduct tests in an attempt to reopen as soon as possible. Structured programs scheduled at the lake have also been cancelled or reformatted.

No specific cause has been identified for the higher levels at this time. Results can fluctuate based on environmental factors such as rain or wind or temperatures, time of day, number of visitors, wildlife, stormwater runoff, surrounding vegetation and beach characteristics.
