The Deer Creek Dam continues as a key feature of the Provo River Project to maintain a supplemental water supply for agricultural and domestic use in Wasatch, Utah, and Salt Lake Counties. The Deer Creek Reservoir formed by the dam feeds the 42-mile-long Salt Lake Aqueduct and its Terminal Reservoir. A hydroelectric power plant at the dam generates as much as kilowatts that is locally distributed.

Constructed between and the Deer Creek Dam was constructed as the key structure of the Bureau of Reclamation's Provo River Project, the largest water resource development project undertaken in Utah. It was the second largest earth fill dam constructed by Reclamation at the time, and Reclamation's first project intended to provide domestic water. The Provo River Project followed a precedent of 40 Federal reclamation projects that had been or were nearly completed by Its construction was during a significant period of Deer Creek Dam, Dam HAER No. UT-93-A (page 2) accelerated American infrastructure development founded on technological investment intended to make the West a sustainable, viable, and profitable landscape.

For additional information regarding the construction of the Deer Creek Dam, refer to "Deer Creek Dam CCC Government Camp," HABS No. UT-137. This HAER project was undertaken by the Utah Department of Transportation in order to document the historic features of the dam prior to the realignment and improvement of U. S. Highway 189 in the area. Preparation for construction of the Deer Creek portion has been underway since the and the work is expected to begin in The field work, site plan, historical reports, and photographs were prepared by Alpine Archaeological Consultants, Inc., Montrose, Colorado. Jonathon C. Horn served as the Principal Investigator, and. Gianfranco Archimede conducted the fieldwork, historic research, large-format photography, and report preparation.

Gianfranco Archimede, Alpine Archaeological Consultants, Inc., April Deer Creek Dam, Dam HAER No. UT-93-A (page 3) The Deer Creek Dam is a rolled, earth-filled embankment structure approximately feet long, 35 feet thick at its crest, feet thick at its base, 155 feet high above the river, and 240 feet high above its bedrock foundation. Its axis is oriented generally northwest to southeast across the Provo River just north of the confluence of Deer Creek and the Provo River. The total volume of the embankments, including the earth, sand, gravel and rock fill portions of the dam, is approximately cubic yards. The upstream slope of the embankment is surfaced with a layer of rock riprap 3 feet thick, and the downstream slope is covered with heavy rock fill.

A concrete cutoff wall, whose footing extends between 4 to 8 feet into the bedrock, was constructed under the upstream embankment. Another cutoff wall, under the axis of the dam, extends downward from the crest the full length of the rock surface of the east dam abutment into the dam foundation. The principal features of the dam include a diversion tunnel and outlet control works through the east dam abutment and an open-channel spillway system in the west dam abutment. There is a 150 by 200-foot triangular-shaped auto parking area on the east abutment adjacent to U.S. Highway where the temporary highway diversion road constructed in reconnected with the highway.

The Deer Creek Dam was the second largest earth fill dam constructed by Reclamation at the time, exceeded only by the Vallecito Dam of the Pine River Project in Colorado. 1 The outlet works consists of a vertical trash rack inlet structure near the east abutment on the upstream side connected to a 12-foot-diameter concrete-lined tunnel 441 feet long. Two 5 by 6-foot high-pressure slide gates are installed in a 52- foot-long transition section at the midpoint of the tunnel's length, where the tunnel splits into two 72-inch-diameter welded steel penstocks.

Originally the gates were hydraulically operated from the concrete gate chamber above them, but the controls were relocated to the power plant during its construction in A horseshoe- shaped tunnel, 11 feet high, 17 feet wide, and 391 feet long, contains the two 72- inch-diameter penstocks running to the valve house substructure. Two tube valves installed near the pipe outlets are used to control water flow into the tailrace. The valve house substructure was originally designed for adaptation as a double turbine hydroelectric plant, with diversion pipes off of each main penstock for by-pass 1 U.S. Department of the Interior, Bureau of Reclamation, Project History: Provo River Project- Utah, Deer Creek Division, Vol. II, submitted by E. 0.

Larson, Construction Engineer (Provo: UT: Bureau of Reclamation), p. "General Information Concerning the Provo River Project, Utah," press release of project report issued by Bureau of Reclamation Commissioner John C. Page, Nov. 1, Deer Creek Dam, Dam HAER No. UT-93-A (page 4) purposes. Although funding for the powerplant was approved in it was not until that the contract was awarded (see HAER No. UT-93-B). 2 The concrete spillway is situated in the west dam abutment, and is oriented north to south. A curved, concrete-lined intake trough on the upstream side measuring 45 feet across the bottom and approximately 165 feet long leads to the two 21-foot-long by 20-foot-high radial spillway gates housed in the spillway gate structure.

The curved gates arc lifted with cables on individual electric motors housed on the upper level of the spillway gate structure that rises above the roadway at the dam's crest. The gates allow the reservoir to spill or overflow when it has reached maximum capacity. Water released by the gates enters a concrete- lined, 953-foot-long by 30-foot wide, open chute that carries the water from the crest of the dam to its base on the downstream side. The spillway chute widens to 75 feet across at its bottom and drops 16 feet into the stilling basin. The stilling basin has two dentated concrete sills across its bottom to slow the incoming water. A riprap- lined, 75-foot-wide canal carries the water 700 feet south from the stilling basin to join the Provo River. 2 Tina M.
