The small dam on Crystal Lake is predated only by those on Wall, Washington and Trial lakes in the Bonnevilie Unit. A typical earth-fill structure, the dam is presently among the most deteriorated in the unit. Its physical integrity has been compromised somewhat by the installation of a new headgate.

Historical Information
In May the National Forest Service granted permission to the Provo Reservoir Company and the Sego Irrigation Company of Provo, Utah, and the Wasatch Irrigation Company and the Timpanogos Irrigation Company of Heber City, Utah, to dam several lakes at the headwaters of the North Fork of the Provo River for irrigation. Of the lakes approved for modification Crystal, Wall, Trial, Washington and Star -- Crystal was the smallest and shallowest. It was also the fourth on which a dam was completed in The dam was a small-scale, earth-fill structure, 70 feet long and only 6 feet high, placed across the lake's outlet on its eastern edge. A gated outlet pipe was embedded in its center, and a concrete overflow spillway was poured at its northern end.
The dam was breached in the In a new headgate was installed and the dam refaced with stone riprap. It is proposed that the existing breach be widened and the spillway deepened to return the lake to its natural level.
