Marsh Dam, located in Richardson County, Nebraska, was completed in 2004 by the USDA NRCS and serves as a crucial infrastructure for flood risk reduction along Contrary Creek. This privately owned Earth dam stands at a height of 30 feet and spans 488 feet in length, with a storage capacity of 18 acre-feet. The dam's primary purpose is flood risk reduction, with a low hazard potential and satisfactory condition assessment as of the last inspection in 2016.

Managed by the Nebraska Department of Natural Resources, Marsh Dam is regulated, permitted, inspected, and enforced by state authorities to ensure its structural integrity and operational effectiveness. Despite its relatively small surface area of 1 acre and drainage area of 0.1 square miles, the dam plays a significant role in protecting the surrounding area from potential flooding events. With its stone core and soil foundation, Marsh Dam exemplifies the importance of water resource management and climate resilience in safeguarding communities and ecosystems against the impacts of extreme weather events.
