Petersen Dam 4028, located in Nuckolls, Nebraska, is a privately owned structure that plays a crucial role in flood risk reduction along the Republican River. Completed in 1960, this earth dam stands at a height of 20.6 feet and has a storage capacity of 53.8 acre-feet, with a normal storage level of 15.7 acre-feet. Despite its low hazard potential, the dam is currently assessed to be in poor condition as of the last inspection in April 2017.

Managed by the Nebraska Department of Natural Resources (NE DNR), Petersen Dam 4028 serves as a vital infrastructure component within the region, ensuring protection against potential flooding events. The dam's primary purpose is flood risk reduction, with a focus on safeguarding the surrounding areas from water damage during periods of elevated streamflow. Although the dam's condition assessment raises some concerns, ongoing state oversight and enforcement activities help to maintain its operational integrity.

With a drainage area of 0.14 square miles and a surface area of 3.4 acres, Petersen Dam 4028 stands as a testament to the importance of water resource management in mitigating natural hazards. As climate change continues to impact weather patterns and increase the frequency of extreme events, the role of structures like Petersen Dam in safeguarding communities becomes increasingly significant. By prioritizing regular inspections and maintenance, stakeholders can ensure the long-term resilience of this essential flood control infrastructure.
