U.S. Representative Mike Ross Secures $7
Million in House for Blakely Mountain Dam.
Blakely Dam itself is composed of rolled earth, almost four million cubic yards of earth. It is 231 feet high and 1100 feet wide. The optimum lake level is 578' above sea level. If the level reaches 592' the water would flow through an emergency 200 feet wide spillway located one mile west of the dam and then into Lake Hamilton. This has never happened since the gates where closed in 1953 however in December 1982 - January 1983, the lake did reach 591.2 feet, just .8 of a foot short of going through the spillway.
The COE area covers 82,000 acres. At 578 feet, 40,100 acres of the project is covered by the lake. 690 miles around the shoreline. At 592 ft above sea level it would be 975 miles around the shoreline and the flood control pool would be 48,300 acres. Drainage area is 1105 sq. miles. Total storage capacity 2,768,000 acre feet. (One acre foot equals one acre of water one foot deep). The hills that surround the lake range up to 1,350'.
