The Flood Control Act of 1946 was passed by the United States Congress on July 24, 1946; to authorize 123 projects including several dams and hydroelectric power plants like Old Hickory Lock and Dam in Tennessee and the Fort Randall Dam in South Dakota. It also allowed bank adjustments and re-directions for several rivers. The plan authorized the Secretary of War to regulate the surveillance of flood control and other improvements as well as the ability to call for a review of said surveys. The Secretary of Agriculture and the Department of Engineers were also charged with conducting surveys relating to their respective fields.


The plan allocated $1,427,097,038 for the projects. The act also allotted a maximum of $1,000,000 annually to be used for removing debris and clearing channels, $2,000,000 to be used for rescue and repair of levees damaged by flooding, and $957,000,000 to be used for other miscellaneous actions.
