Trial Lake (Summit) is located on the north side of US-150 in the western Uinta Mountains. Kamas is 21.6 miles (34.76 km) to the west. in 1893 it was the first lake in the area used as a reservoir on a "trial" basis. Hence the name Trial Lake. In 1914 it was enlarged by construction of an earth-fill dam to create an intermediate-sized artificial impoundment which still serves as a source of irrigation water today. Other lakes in the area include Wall Lake, Washington Lake, Crystal Lake, Lily and Teapot Lakes. With the exception of Wall Lake, all have campgrounds. The lake is stocked annually with thousands of catchable trout. Some native species of fish may also still reside in the lake.
