Document Description
The proposed project consists of construction of a grade control structure and excavation of between 270,000 and 540,000 cubic yards of material from the Reservoir, followed by excavation of approximately 54,000 cubic yards annually. Initially excavation would commence just upstream of the Dam and extend to River Station 3,037. PWD would construct a grade control structure at or just downstream of River Station 4,235 (the Rocky Point area) and excavate downstream of the grade control. The structure would be constructed of soil cement or concrete and span approximately 250 feet of the channel. The structure would be buried, with the top flush with, or slightly below, the existing channel surface. Maximum depth of the structure would be buried, with the top flush with, or slightly below, the existing channel surface. Maximum depth of the structure would be approximately 70 feet. Construction of the structure would result in a temporary disturbance to a section of channel and adjacent bank approximately 300 feet wide in width and 500 feet wide in the direction parallel to flow.
