Bergeson Dam, located in Cherokee, Iowa, was completed in 1959 and serves multiple purposes including fire protection, stock, and a small fish pond. Owned and regulated by a private entity, the dam is under the jurisdiction of the Iowa Department of Natural Resources and is subject to state permitting, inspection, and enforcement. Designed by the USDA NRCS, the earth dam stands at a height of 31 feet and stretches for 406 feet along the TR-Little Sioux River.

With a storage capacity of 32 acre-feet, Bergeson Dam has a low hazard potential and is currently rated as "Not Rated" in terms of condition assessment. The spillway type is uncontrolled, and the dam has a moderate risk assessment rating of 3. While there are no outlet gates or associated structures, the dam's purpose and design make it a vital resource for water management in the area. As climate change continues to impact water resources, Bergeson Dam plays a crucial role in ensuring water availability for the surrounding community and ecosystem.
