Pisgah Dam, located in Minnesota along the Ottertail River, is a hydroelectric facility with a primary purpose of generating power. Completed in 1918, the dam stands at a height of 26 feet and has a storage capacity of 250 acre-feet. With a low hazard potential and a very high risk assessment rating, the dam is regulated by the Federal Energy Regulatory Commission and inspected regularly to ensure its structural integrity.

The dam serves multiple purposes beyond power generation, including fish and wildlife conservation, recreation, and water supply. It has a controlled spillway and is equipped with six slide gates for water release. The surrounding area covers 70 acres and the drainage area for the dam is 1355 square miles. Despite its age, Pisgah Dam continues to operate effectively, meeting state permitting and inspection requirements.

With Collin Peterson as the congressional representative overseeing the area, Pisgah Dam stands as a historic landmark that not only provides essential services but also contributes to the local ecosystem. Its role in water resource management and climate resilience makes it an important asset for the community and a point of interest for water resource and climate enthusiasts alike.
