High Mountain Dams in Bonneville Unit, Marjorie Lake Dam, Wasatch National Forest, Kamas, Summit County, UT

Significance: Typical earth-fill structures, the dams on Marjorie and Duck lakes were constructed using similar specifications, including the stipulation for "carefully hand-laid rock faces." They are representative of a more aesthetic dam engineering philosophy which resulted from National Forest Service multi-use goals. Marjorie and Duck lakes are significant as the last reservoirs created on the upper Provo River drainage prior to Federal involvement in Utah's irrigation dam construction.
