Deer Valley, located in Heber City, Utah, is a privately owned irrigation dam on Lake Creek that was completed in 1888 by the USDA NRCS. The dam has a hydraulic height of 22 feet and a structural height of 26 feet, with a length of 566 feet. It provides a storage capacity of 184 acre-feet, with normal storage levels at 138 acre-feet. The dam is regulated by the Utah Division of Water Rights and undergoes regular inspections to ensure its safety and functionality.

Despite its age, Deer Valley dam is considered to be in fair condition with a high hazard potential. The dam is primarily used for irrigation purposes and serves the surrounding area in Wasatch County. The dam has not been significantly modified in recent years, and its last inspection in October 2020 showed that it meets regulatory guidelines. With its historical significance and importance for water resource management in the region, Deer Valley dam remains a vital piece of infrastructure that continues to play a key role in supporting agriculture and water supply in the area.
