Bagnell Dam, Osage Beach

3.2
#4 of 6 in Parks in Lake of the Ozarks
Bagnell Dam impounds the Osage River in the U.S. state of Missouri, creating the Lake of the Ozarks. The 148foot tall concrete gravity dam was built by the Union Electric Company (now AmerenUE) for the purpose of hydroelectric power generation as its Osage Powerplant. It is 2543ft long, including a 520ft long spillway and a 511ft long power station. The facility with eight generators has a maximum capacity of 215 megawatts.
The dam derives its name from Bagnell, Missouri at the dam site which preceded the dam. It in turn derives its name from William Bagnell, who platted the town in 1883. A variant name is the "Osage Dam".
The dam is located in the city of Lakeside in Miller County, near the Camden-Miller County line.
Construction started on the dam in 1929 and was completed in 1931. The resulting reservoir, the Lake of the Ozarks, has a surface area of, over 1150mi of shoreline (1850 km), and stretches 94mi from end to end. At the time of construction it was one of the largest man-made lakes in the world and the largest in the United States.
The concept of a hydro electric power plant on the Osage River was first introduced by a Kansas City developer as long ago as 1912. Ralph Street managed to put together the funding to construct a dam across the Osage River and began building roads, railroads and support structures necessary to begin construction of a dam that would impound a much smaller lake than what is now known as Lake of the Ozarks. Sometime in the mid-1920s, Street’s funding dried up and he had to abandon the idea of the first hydroelectric power plant on the Osage River.

  • We drove across and visited the Willmore Lodge first. We did stop at the scenic overlook but it was less than thrilling. We then found the historic site at the bottom of the dam which was awesome! So ...  more »
