From Bureau of Reclamation:
We hope you enjoyed your weekend! It's time to introduce our #DamOfTheWeek, Horse Mesa Dam, located in Arizona.
The spillway, as modified in 1936-1937 by the Bureau of Reclamation, includes a 50,000 cubic foot per second, concrete-lined auxiliary tunnel, 30 feet in diameter and 400 feet long; a regulating gate, gatehouse, and operating mechanism for controlling the tunnel; and a concrete discharge apron below the existing spillway.
The piers on the radial-gate spillways were thickened, individual motor-driven gate hoists were installed, and two 15-kilovolt-ampere gasoline-engine driven generators were installed for emergency operation of the hoist motors.
