Edgar Dam, located in Saunders County, Nebraska, is owned and regulated by the local government with oversight from the Nebraska Department of Natural Resources. This earth dam, completed in 1960, serves primarily for flood risk reduction along the TR-Rock Creek. Standing at a height of 21 feet and a length of 350 feet, Edgar Dam has a storage capacity of 78 acre-feet and a maximum discharge of 993 cubic feet per second.

Despite its low hazard potential, the dam is currently in poor condition as of the last inspection in May 2016. With a frequency of inspection every 5 years, the dam's emergency action plan and risk assessment measures need to be updated. As water resource and climate enthusiasts, it is crucial to monitor and advocate for the maintenance and improvement of infrastructure like Edgar Dam to ensure public safety and effective water management in the region.
