These gates will be operated only during periods of high runoff. The dam was completed except, for oiling of the road which traverses the crest, in the autumn of 1941. The road oiling was to have been finished before the summer of 1942. Provision has been made for the ultimate development of power possibilities. A concrete lined, open channel spillway, 952 feet long, terminating in a stilling basin, is located at the right abutment. Discharge through the spillway will be controlled by two radial Relocated Railroad Construction of the reservoir compelled relocation of the Denver & Rio 85.

The gate chamber is located inside the dam about 500 feet from outlet side, and is reached by a catwalk between the two steel outlet pipes. ( See photograph No. 101, page 85.) The two huge hydraulic ally operated valves regulate the flow of water from the reservoir into the Provo River channel below the dam. L. Clyde Anderson |
