Jorgensen Dam, located in Guthrie, Iowa, is a private dam designed by the USDA NRCS and completed in 1971. With a primary purpose of fire protection, stock, or small fish pond, this Earth dam stands at a height of 34 feet and stretches 352 feet in length. It has a normal storage capacity of 27 acre-feet and a maximum storage of 100 acre-feet, serving as a key asset for water resource management in the area.

Managed by the Iowa Department of Natural Resources, Jorgensen Dam is regulated, permitted, inspected, and enforced by state authorities to ensure its safety and functionality. Despite being classified with a low hazard potential, the dam is considered to have a moderate risk level (3) and its condition is currently not rated. While it has not been modified in recent years, regular inspections are crucial to monitor its performance and address any potential risks or issues that may arise in the future.

Situated on TR-BEAR GROVE CREEK, a tributary of the South Raccoon River, Jorgensen Dam plays a vital role in water storage and flood control efforts in the region. With its strategic location and design, the dam serves as a valuable resource for the local community, providing essential water supply and environmental benefits while also contributing to the overall climate resilience of the area.
