Murphy Dam, located in Swanton, Nebraska, is a privately owned structure designed by the USDA NRCS for flood risk reduction. Completed in 1971, this earth dam stands at a height of 16.8 feet and spans 500 feet in length, with a storage capacity of 68 acre-feet. Situated on the TR-Swan Creek, the dam serves the primary purpose of flood risk reduction and is regulated by the Nebraska Department of Natural Resources.

Despite its low hazard potential, Murphy Dam's condition assessment in 2017 revealed poor structural integrity, prompting the need for regular inspections every five years. The dam's poor condition underscores the importance of ongoing maintenance and potential rehabilitation efforts to ensure its effectiveness in managing flood risks in the region. With a drainage area of 0.7 square miles and a maximum discharge capacity of 212 cubic feet per second, Murphy Dam plays a crucial role in protecting the surrounding Saline County community from potential flooding events.

As a vital component of the local water resource infrastructure, Murphy Dam serves as a critical line of defense against floodwaters, safeguarding the residents and agricultural lands in the area. With its historical significance dating back to the early 1970s, the dam's ongoing maintenance and inspection protocols are essential to uphold its functionality and support the region's resilience to climate-related challenges. The collaboration between private ownership and state regulatory agencies like the Nebraska Department of Natural Resources ensures that Murphy Dam continues to fulfill its role in flood risk reduction and water resource management for years to come.
