| The Vandalia Diversion Dam on Milk River, 3 miles west of Vandalia, MT, is a reinforced concrete slab and buttress weir-type structure with movable crest gates and auxiliary overflow crest. The hydraulic height is 27 feet; the crest length is 2,340 feet. The auxiliary crest, 1,200 feet in length, is located north of Milk River opposite the dam to provide adequate channel for extreme floodflows. The Vandalia Canal diverts on the south side of the river at the dam and conveys water to the land in the Glasgow Division. The canal has a design capacity of 300 cubic feet per second. |
