High Mountain Dams in Bonneville Unit, Washington Lake Dam, Kamas, Summit County, UT

Significance: Washington Lake is the 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 impound a natural lake in the upper Provo River drainage, along with the dams on Trial 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 high visibility, Washington is one of the most significant of the Bonneville Unit dams.
