ordered a feasibility study to be done on the Clark Hill Project amongst other dams in the plan. The results were sent back to the President in 1937 and other reviews were conducted until focus on the Second World War slowed the approval process. The next comprehensive study on the Upper Savannah Basin was not completed until 1943 but the project was authorized by Congress with Public Law 534 in 1944. A clerical error at the time named the project "Clark Hill" instead of "Clarks Hill". The final report on the Upper Savannah Basin was issued in 1946 and initial construction began soon thereafter on August 1. Construction was at first ceased until November 1946 as President Harry S. Truman had halted funding for many government programs in order to handle a post-Second World War depressed economy. In 1947, diversion of the Savannah River and construction of a coffer dam began while the contract for the actual dam was awarded. The construction plant for the dam was also completed in 1947, containing equipment to create concrete that would be transported anywhere on the construction site via three-revolving gantry cranes with 124 ft. booms. In 1948, after the foundation was excavated, workers began to pour concrete on site for the spillway. In 1949, initial work on the concrete spillway was completed; the original coffer dam was removed and a second cofferdam was installed in order to restore the flow of the Savannah River to its original channel but now through eight-sluice gates in the spillway structure. Concrete operations on the main part of the dam had halted in 1949 because of a steel-strike but resumed in 1950 and much of the spillway was completed by the end of the year. In late 1950, contracts for construction of the powerhouse were awarded and the contracts for the 7 generators had been awarded a year prior. Construction on the powerhouse would lag initially because materials were needed for the Korean War but by July 1952, 60% of the powerhouse was complete. Each generator required for the power house needed 32 railcars to transport on site. By July 1951, the reservoir began to fill as most of the embankment part of the dam was complete and filling would finish in October 1952. By November 1952, the first generator was operating and began transferring power to South Carolina early the next year. The six remaining
