The Deer Creek Darn 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 darn feeds the 42-rnile-long Salt Lake Aqueduct and its Terminal Reservoir. The hydroelectric powerplant at the darn generates as much as kilowatts that is locally distributed.

Constructed between and the Deer Creek Darn 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 darn 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 accelerated American infrastructure development founded on technological investment intended to make the West a sustainable, viable, and profitable landscape.

Gianfranco Archimede, Alpine Archaeological Consultants, Inc., April Deer Creek Dam, Salt Lake Aqueduct Intake Control Gate HAER No. UT-93-E (page 3) Although Deer Creek Dam was constructed between and modifications and additions were made to the dam after its completion. The Salt Lake Aqueduct was completed in 12 years after its construction began. The intake for the aqueduct was through the control gate on the west side of the Deer Creek Powerplant tailrace (HAER No. UT-93-D). The intake gate was installed in with the completion of the Salt Lake Aqueduct. It functioned to regulate water flow through the aqueduct between its origin at the base of the Deer Creek Dam and its terminus at the Terminal Reservoir in Salt Lake City.

The fixed-wheel gate was operated by an electric winch to pull a cable attached to the gate. The winch was mounted to a vertical steel framework situated directly above the gate at the top edge of the tailrace riprap. The winch framework was anchored into a 15 by 18-foot poured concrete floor that was likely covered by a structure (no structure exists today). A 5-foot-wide poured concrete chute slopes downward across the tailrace riprap from the winch area to the submerged gate. A 4-inch-wide iron channel imbedded in the center of the concrete chute carried the cable between the winch and the gate. A steel stairway running along the south side of the concrete chute provided access to the intake gate.

The dimensions and character of the gate itself are unknown, as it is submerged in the tailrace. The gate was automatically controlled by a flow meter mechanism in the venturi structure which had a rate- setting device inside of the recording cabinet. The device was set manually to the desired flow in the aqueduct, and, through a system of electrical relays, the gate hoist motor opened or closed the gate to adjust the water flow for the desired setting. The gate hoist motor could also be operated manually by push buttons to open, close, or stop the gate. 1 The intake gate was replaced by a more sophisticated gate control system, situated on the west side of the tailrace and south of the original control gate. Although the original gate itself was left in place, it is no longer used.
