Trial Lake is the second largest body of water to be reservoired in the Bonneville Unit of the Central Utah Project. Its dam, built cooperatively by four of the principal regional irrigation companies, is the oldest man- made structure to reservoir a natural lake in the upper Provo River drainage, along with the dams on Wall and Washington lakes. Although standard in its sloped profile and steel outlet works, the dam is technologically notable as having a concrete core beneath its earth-fill construction. An easily accessible structure with a high visibility, Trial is one of the most significant of the Bonneville Unit dams.

Historical Information
The Provo River originates from Trial Lake, the second largest of the reservoired lakes in the Bonneville Unit. In May the National Forest Service granted permission to the Provo Reservoir Company and the Sego Irrigation Company of Provo, Utah, and to the Wasatch and Timpanogos Irrigation companies of Heber City, Utah, to dam Trial and four other lakes in the area for irrigation water storage. A pair of medium-scale dams was completed later that year across the natural outlet for Trial Lake at its southern end. Six hundred feet long and 40 feet high, the primary dam consisted of compacted earth fill over a concrete core, with 18" of stone riprap on its sloped upstream and downstream faces.
The outlet was an 18" diameter riveted steel pipe, with a slide headgate at the pipe inlet and a 20" Ludlow gate valve on the downstream toe. The dam and outlet works remain in good condition. It is proposed that the dam be reconfigured, the spillway lowered and new outlet works installed to lower the level of the lake.
