Birch Lake, located in Minnesota, is a picturesque reservoir formed by a rockfill dam completed in 1922 on the Kawishiwi River. With a surface area of 7,624 acres and a maximum storage capacity of 39,680 acre-feet, this dam primarily serves recreational purposes for water and climate enthusiasts. The controlled spillway with a width of 162 feet ensures efficient water management and flood risk reduction in the area.

Managed by the Federal Energy Regulatory Commission, Birch Lake has a low hazard potential and a very high risk assessment rating. Despite not having a detailed condition assessment available, the dam undergoes regular inspections every three years. Its emergency action plan was last revised in December 2019, demonstrating a commitment to ensuring the safety and integrity of this vital water resource. For those interested in fish and wildlife preservation, flood risk management, and recreational activities, Birch Lake offers a serene and well-maintained environment to explore and enjoy.
