Fort Loudon Dam was the last of seven main-river dams proposed for construction in TVA's report to Congress dated March 31, 1936, and is the upper link in the chain of dams for navigation envisioned in the TVA Act. A record of the more important facts concerning planning, design, construction, cost, and initial operations of this major unit in the integrated water-control system is contained herein as Technical Report No. 11. It has been prepared from detailed reports in the files of TVA and has been edited to present special coverage to new or unprecedented procedures with relatively less emphasis on standard practices of engineering and construction.
