Document Description
A portion of the Gate 11 stilling invert, approximately 20 feet downstream of the gate sill has eroded. The hole is roughly oval in shape, up to 16 feet wide, 24 feet long and 2 feet deep, at a water depth of 15 feet. Repairs are needed to maintain the integrity of this key portion of Gate 11, which is used as a regulatory gate for minor adjustments of water levels and to flush sediments that otherwise would impair the performance of the right bank fish ladder. The principal components of the project are 1) cleanup stilling basin to remove rocks, gravel, sand, rebar, trash, loose materials and other debris; 2) selectively remove damaged concrete from stilling basin; 3) furnish and install concrete anchors to stabilize new concrete to existing structure and 4) construct cast-in-place reinforced concrete to repair stilling basin structure.
