Hailed as the most skillful engineering feat of its day, actual
construction of Bagnell Dam (and what was at that time the world¹s
largest man-made lake), began August 6, 1929 by Union Electric Company
of St. Louis, MO (now AmerenUE).
Four months after construction began, the
stock market crashed. While the rest of the nation was caught
in The Great Depression, the mammoth Bagnell undertaking brought
about a growth and expansion to central Missouri which continues
today. Some 4,600 workers were employed at one time, among
20,500 total individuals,
over two years.
The project was divided into three categories. The dam and
power house included construction of all features relating
to the structure and generating plant. These included a camp,
roads, railroad tracks and temporary structures. Transmission
lines included all manner of design, location and construction
of the lines to carry electricity to the marketplace. The
reservoir included location, land surveys and mapping of what
is now the Lake of the Ozarks.
Once cleared, the reservoir was outlined. The Osage River
was impounded and the lake began to fill on February 2, 1931.
The lake was opened to travel May 30, 1931. Backwaters extended
up the Niangua, Grand Glaize, Grand and Pomme de Terre rivers.
The reservoir encompasses 92 square miles, or some 54,000
acres of which 30,000 acres required clearing.
The dam is of concrete gravity type, 2,543ft long. It consists
of a 511ft long power station, 520ft long spillway section
and two non-overflow retaining sections adjacent to the river
banks. The dam supports a concrete highway structure, which
includes a 20ft wide roadway and a 3ft sidewalk, both spanning
the entire length of the dam. The 215,000 kilowatt capacity
power plant provides electricity to a large area of the state.
The Lake covers 54,000 acres, impounds 646 billion gallons
of water and has 1,150 miles of cove indented shoreline. These
immense statistical facts have created the opportunity for
the spectacular tourism area we all enjoy today. Thousands
of visitors travel here every year to enjoy the beauty and
recreation that was brought about by the Great Osage River
Project. |
