About this property

Bagnell Dam (informally, the Osage Dam) impounds the Osage River in the U.S. state of Missouri, creating the Lake of the Ozarks. The dam is located in the city of Lakeside in Miller County, near the Camden-Miller County line. The 148-foot (45 m) tall concrete gravity dam was built by the Union Electric Company (now Ameren) to generate hydroelectric power at its Osage Powerplant. It is 2,543 feet (775 m) long, including a 520-foot (160 m) long spillway and a 511-foot (156 m) long power station. The facility with eight generators has a maximum capacity of 215 megawatts. The dam provides power to 42,000 homes. The dam also creates Bagnell Dam Boulevard (formerly US 54 prior to 1968, then formally US 54 Business Route), a narrow two-lane highway connecting the nearby Bagnell Dam Strip with Lakeland and U.S. Route 54. The dam is named for the nearby town of Bagnell, Missouri, which was named for William Bagnell, who platted the town in 1883.
