High Mountain Dams in Upalco Unit, Clements Lake Dam, Ashley National Forest, 6.5 miles North of Miners Gulch Campground, Mountain Home, Duchesne County, UT

Significance: The largest of the Brown Duck Basin dams, the Clements Lake Dam is a representative, though undistinguished, example of clay core/earth fill technology found in the Upalco Unit. Its principal significance derives from its association with the Dry Gulch Irrigation Company. With by far the most extensive network of canals and laterals, Dry Gulch was the largest and most important irrigation company in the Uinta Basin. The company impounded five lakes in the Uintah Unit of the Central Utah Project, but Clements Lake is the only Dry Gulch reservoir in the Lake Fork drainage. As such, it is an integral component of an historically important irrigation system.
