Southfork Dam, located in Clive, Iowa, is a privately owned structure designed by Bishop Engineering and regulated by the Iowa Department of Natural Resources. Completed in 1988, this Earth-type dam stands at a height of 38 feet and spans 560 feet, with a storage capacity of 204 acre-feet. The dam serves multiple purposes, including recreation, and is situated on the TR-Walnut Creek, within the Rock Island District.

The dam features an uncontrolled spillway with a width of 7 feet and has undergone regular inspections, with the next one scheduled for 2023. Despite its age, the dam continues to provide valuable water resource management for the area, supporting a surface area of 9 acres and a drainage area of 0.75 square miles.

Enthusiasts of water resources and climate will appreciate the strategic location and design of Southfork Dam, which not only ensures water storage and flood control but also offers recreational opportunities for the community.
