Black Eagle Dam, Gravity dam on Missouri River in Cascade County, Montana.
The concrete structure extends 782 feet in length and reaches 34.5 feet in height, containing three turbines for hydroelectric power generation.
Montana Power Company constructed the current concrete dam in 1927 to replace the original 1890 timber-and-rock structure, which remains submerged in the reservoir.
The dam contributed to Great Falls receiving the name 'The Electric City' as it represented the first hydroelectric facility in Montana and on the Missouri River.
The reservoir, known as Long Pool, extends approximately 2 miles and maintains a storage capacity between 1,710 and 1,820 acre-feet of water.
Meriwether Lewis first documented Black Eagle Falls on June 13, 1805, noting the natural 26.42-foot water drop before the dam construction.
