Fort Peck Dam, Charles M. Russell National Wildlife Refuge

The Fort Peck Dam is the highest of six major dams along the Missouri River, located in northeast Montana in the United States, near Glasgow, and adjacent to the community of Fort Peck. At 21,026 feet in length and over 250 feet in height, it is the largest hydraulically filled dam in the United States, and creates Fort Peck Lake, the fifth largest artificial lake in the U.S. more than 130 miles long, 200 feet deep, and it has a 1,520-mile shoreline which is longer than the state of California's coastline. It lies within the Charles M. Russell National Wildlife Refuge. The dam and the 134-mile-long lake are owned and operated by the U.S. Army Corps of Engineers and exist for the purposes of hydroelectric power generation, flood control, and water quality management.
