Korgan Dam, located in Clay County, Nebraska, is a privately owned earth dam primarily used for irrigation purposes. Constructed in 1982 by the USDA NRCS, this dam stands at a height of 21 feet with a hydraulic height of 21 feet and a structural height of 26 feet. With a storage capacity of 134 acre-feet, the dam serves the surrounding area for agricultural water needs, holding back the waters of the TR-W FK Big Blue River.

Although the dam has a low hazard potential, its condition assessment is rated as poor as of the last inspection in May 2018. The inspection frequency is every 5 years, with the next assessment due in 2023. The dam's emergency action plan readiness, risk assessment, and management measures are not currently available, highlighting areas for improvement in ensuring the safety and reliability of this vital water resource infrastructure. For water resource and climate enthusiasts, monitoring the maintenance and upgrades of Korgan Dam will be crucial in safeguarding its functionality and mitigating potential risks associated with its operation.
