Deer Creek Dam, located in Sioux City, Iowa, was completed in 1995 and serves as a vital water resource for the area. Owned by the state and regulated by the Iowa Department of Natural Resources, this earth dam stands at a height of 55 feet and spans a length of 745 feet. With a storage capacity of 1400 acre-feet and a surface area of 44 acres, Deer Creek Dam primarily caters to recreational purposes, offering opportunities for activities like boating and fishing.

Despite its high hazard potential, Deer Creek Dam has been assessed as being in satisfactory condition, with inspections conducted every two years to ensure its safety and functionality. The dam's spillway, classified as uncontrolled, has a width of 5 feet, allowing for the controlled release of excess water during periods of heavy rainfall. With a moderate risk assessment rating, Deer Creek Dam continues to play a crucial role in managing water resources and mitigating the impacts of potential flooding events in the region.
