Pillager is a historic hydroelectric dam located in Pillager, Minnesota, along the Crow Wing River. Built in 1917, this dam stands at 22 feet tall and stretches 903 feet in length, with a maximum discharge capacity of 21,000 cubic feet per second. With a normal storage capacity of 4,608 acre-feet and a maximum storage capacity of 4,853 acre-feet, this dam plays a crucial role in water resource management in the area.

Managed by the Federal Energy Regulatory Commission, Pillager Dam is classified as having a high hazard potential due to its location and structural characteristics. Despite its age, the dam's risk assessment is rated as "Very High (1)", highlighting the need for ongoing monitoring and maintenance to ensure public safety and environmental protection. The dam features a controlled spillway and two slide gates for water release, and it is subject to regular state inspection, enforcement, and permitting by the Minnesota Department of Natural Resources.

For water resource and climate enthusiasts, Pillager Dam offers a fascinating glimpse into the history of hydroelectric infrastructure and its impact on the surrounding ecosystem. Its location in Cass County, Minnesota, and its role in regulating water flow on the Crow Wing River make it a key player in the region's water management strategies. As efforts continue to assess and mitigate risks associated with the dam, its importance in balancing water supply, flood control, and environmental preservation becomes increasingly evident in the face of changing climate patterns.
