This fall, the U.S. Army Corps of Engineers, Rock Island District, reduced Lake Red Rock’s reservoir pool level to elevation 732 mean sea level from 742 msl in preparation for flood recovery work. This drawdown was made to expose Tainter gate cable attachment hardware, which is underwater at normal reservoir levels, to enable replacement of the lifting cables. The ten-foot drawdown was originally scheduled to be completed in mid-December. However, due to a contract modification for cable replacement, the drawdown has been extended to February 12, 2011.
Kovilic Construction - Frankin Park, Illinois, is the contractor for the dam mechanical contract which includes Tainter and sluice gate bulkhead installation, cable replacement, and mechanical repairs.
