West Regional Conference: AV Watkins Dam Field Trip

Twelve miles northwest of Ogden on the shore of the Great Salt Lake, Arthur V. Watkins Dam is an offstream structure with a structural height of 36 feet. The dam is about 14.5 miles long in a rough rectangle, contains about 17 million cubic yards of material, and encloses a reservoir of 222,273 acre-foot capacity. Its siphon spillway has a capacity of 25-30 cubic feet per second. The outlet structure has a capacity of 1,100 cubic feet per second and includes an overflow spillway with a capacity of 21 cubic feet per second.

During the irrigation season, water can be pumped by Willard Pumping Plants No. 1 and No. 2 back through the Willard Canal from Arthur V. Watkins Reservoir to Slaterville Diversion Dam and on into the Layton Pumping Plant intake channel for irrigation of lands lying along the shores of Great Salt Lake.
