International Falls, located in Baudette, MN, is a hydroelectric dam on the Rainy River in Minnesota. Completed in 1909, this gravity dam stands at a height of 29 feet and has a length of 505 feet, with a storage capacity of 77,274 acre-feet. The dam serves multiple purposes including flood risk reduction, recreation, and water supply, while being regulated by the Federal Energy Regulatory Commission.

With a low hazard potential and a moderate risk assessment rating, the International Falls dam is inspected by the FERC every two years to ensure its structural integrity and safety. The dam's uncontrolled spillway has a width of 170 feet, allowing for a maximum discharge of 7,650 cubic feet per second. Despite being a private-owned structure, the dam is subject to state regulation, permitting, inspection, and enforcement by the Minnesota Department of Natural Resources.

As a key feature in the St. Paul District of the US Army Corps of Engineers, the International Falls dam plays a crucial role in managing water resources and climate impacts in the region. Its strategic location and multi-purpose design make it a vital asset for the local community and a critical component in the overall water management system of Minnesota.
