High Mountain Dams in Upalco Unit, Twin Pots Dam, Ashley National Forest, 10.1 miles North of Mountain Home, Mountain Home, Duchesne County, UT

Significance: At the time of its initial construction in 1921, the Twin Pots Dam not only held the largest body of impounded water in the Upalco Unit, it was the first successful attempt to impound running water and create a manmade reservoir. The Twin Pots Reservoir produced a significant increase of irrigation water storage for the Farnsworth company and allowed the expansion of farming in the Mountain Farm area, served by the Farnsworth Canal. The reconstructed dam is an undistinguished, but representative, example of the relatively unsophisticated earth-fill dam technology found in the Uintah Mountains.
