Granite Creek Dam Outlet Rehab Project


Granite Creek Dam Outlet Rehab Project

The Granite Creek Dam Outlet Rehabilitation Project generally consists of the replacement of the inoperable 36″ large diameter valve that controls discharges for Watson Lake, and the sealing and abandonment of the inoperable 48″ large diameter valve, both at Granite Creek Dam constructed in 1919. The proposed 36″ replacement valve is to include a 12″ bypass. The project will provide for operation of the valves from the dam crest via flexible operators. The project also includes the replacement of existing upstream trash racks and installation of new slide gates.
