Overview

• Minnesota DNR confirmed that a mechanical failure left Lake Alice’s control valve stuck open, draining almost all of the 26-acre, spring-fed reservoir.
• Staff discovered broken parts inside the 60-year-old concrete structure during an attempt to close the valve after managing overflow into the St. Croix River.
• The rapid drawdown reduced the lake to a single stream and caused a significant fish kill, prompting emergency salvage operations and plans to restock northern pike and other species.
• Officials estimate that natural springs could refill the lake in under a month following a temporary fix, but full repairs to the antiquated machinery may take several months.
• William O’Brien State Park has suspended boating, swimming and fishing for at least four to six weeks as crews undertake emergency repairs and ecological recovery.
