Wall Lake is the deepest body of water to be reservoired in the Bonnevilie Unit of the Central Utah Project. Its dam, built conservatively 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 Trial and Washington lakes. Picturesquely placed and well- preserved, the dam and outlet works are representative of medium-scale earth-fill construction in the unit. Wall Lake is one of the more significant of the Provo drainage retention structures.

Historical Information
In May the National Forest Service issued a special use permit to the Provo Reservoir Company and the Sego Irrigation Company of Provo, Utah, and the Wasatch and Timpanogos irrigation companies of Heber City to dam several lakes at the headwaters of the North Fork of the Provo River for irrigation. Of the lakes approved for modification -- Crystal, Washington, Trial and Star Wall was the highest feet), deepest feet) and northernmost. It was characterized by an irregular shoreline of talus slopes and scattered conifers. Dams on Washington, Trial and Wall lakes were completed in The Wall Lake Dam, an obtuse V-shaped, 615-foot structure, was made of a compacted clay core, covered with earth and rock waste fill and faced with rock riprap on both upstream and downstream slopes.
The outlet consists of a 20" diameter riveted steel pipe, with an inclined slide headgate at the pipe inlet and a 20" Ludlow gate valve at the downstream toe. Both dam and outlet works remain, although longitudinal cracks have been observed on the dam. Major reconstruction is proposed.
