Locke Lake, also known as Fridley Mill Pond, is a picturesque water resource located in Anoka, Minnesota. Managed by the local government, this recreational lake sits along the Rice Creek with a concrete dam that stands at 21 feet high and 100 feet long. Completed in 1956, Locke Lake offers a surface area of 23 acres and a storage capacity of 320 acre-feet, making it a popular spot for outdoor activities and water enthusiasts.

With a significant hazard potential due to its location and structure, Locke Lake is regularly inspected and maintained to ensure its integrity and safety. The dam's condition has been assessed as satisfactory, with the last inspection conducted in October 2014. Despite the very high risk assessment rating, the lake continues to be a beloved recreational spot in the area, drawing visitors for fishing, boating, and enjoying the natural beauty of the surrounding landscape.

Situated within the St. Paul District of the US Army Corps of Engineers, Locke Lake is a key destination for those interested in water resources and climate. Its controlled spillway, very high risk rating, and historical significance make it a valuable site for studying the intersection of human infrastructure and environmental conservation. As an essential part of the local ecosystem, Locke Lake serves as a reminder of the importance of responsible water management practices in the face of changing climate conditions.
