Williams Dam, located in Hebron, Nebraska, is a privately owned structure with a primary purpose of flood risk reduction. Constructed in 1959 by the USDA NRCS, this earth dam stands at a height of 20 feet and spans 560 feet in length. With a maximum storage capacity of 497 acre-feet and a normal storage of 191 acre-feet, the dam serves to protect the surrounding area, including Turtle Creek, from potential flooding events.

Managed by the Nebraska Department of Natural Resources, Williams Dam is state regulated and subject to regular inspections to ensure its structural integrity and compliance with regulations. Despite being classified as having a low hazard potential, the dam's condition remains unrated as of the last inspection in May 2019. The dam has not been modified in recent years and does not have an Emergency Action Plan in place, indicating a need for continued monitoring and preparedness in the event of an emergency.

In the event of a breach or failure, Williams Dam has a maximum discharge capacity of 2,328 cubic feet per second. With its low hazard potential and state-regulated status, the dam serves as a crucial piece of infrastructure for flood control in the Nuckolls County area. As water resource and climate enthusiasts, staying informed about the condition and management of structures like Williams Dam is vital for understanding and mitigating potential risks associated with extreme weather events.
