Located in Cook, Nebraska, the South Branch 58 dam is a key player in flood risk reduction along the TR-S FK Little Nemaha River. Constructed in 2000 by the USDA NRCS, this earth dam stands at a height of 28 feet, with a hydraulic height of 26 feet and a structural height of 33 feet. With a storage capacity of 214 acre-feet and a drainage area of 0.8 square miles, the dam serves as a vital resource in managing water flow and mitigating potential flooding in the region.

Managed by the Nebraska Department of Natural Resources, the South Branch 58 dam boasts a low hazard potential and is deemed to be in satisfactory condition as of the last assessment in June 2016. With a normal storage capacity of 50 acre-feet and a maximum discharge of 299 cubic feet per second, this dam plays a crucial role in protecting the surrounding community from the impacts of extreme weather events. In addition to its primary purpose of flood risk reduction, the dam also serves as a recreational area, covering 11 acres of surface area for outdoor activities.

With its strategic location and effective design, the South Branch 58 dam stands as a testament to successful collaboration between local government entities and federal agencies. As climate change continues to impact water resources and weather patterns, infrastructure like the South Branch 58 dam will play an increasingly vital role in safeguarding communities and ecosystems from the growing threats of flooding and water scarcity.
