Mechanical Failure Drains Lake Alice at William O'Brien State Park

Lake Alice in William O'Brien State Park, Minnesota, has experienced a near-total drawdown due to a mechanical failure of the water control valve, leaving only a stream remaining in the 26-acre, 9-foot deep lake. The valve was opened to release excess water after heavy rains caused the lake to overflow, but it became stuck open, causing the lake to drain significantly and resulting in a major fish kill affecting species such as walleye, bluegill, largemouth bass, northern pike, and others. The swimming beach is currently closed, and water recreation on the lake is expected to be impacted for at least four to six weeks. DNR staff are working to repair the valve and restore the lake, although there is no definite timeline for the lake to be refilled. Despite the issues at Lake Alice, water activities on the nearby St. Croix River remain available, including fishing, boating, and paddling. The situation is developing as the Minnesota Department of Natural Resources responds to the incident and plans next steps for restoration.
