Cross Group Dam, located in Banner County, Nebraska, is a privately owned structure designed by the USDA NRCS to reduce flood risks in the area. Completed in 1966, this earth dam stands at a height of 35 feet and spans 950 feet in length. With a storage capacity of 315 acre-feet and a drainage area of 2.2 square miles, the dam plays a crucial role in managing water flow along TR-WILLOW CREEK.

Managed by the Nebraska Department of Natural Resources, Cross Group Dam is regulated, inspected, and enforced to ensure its structural integrity and performance. Despite its low hazard potential, the dam's condition assessment in 2017 rated it as satisfactory. With a regular inspection frequency of 5 years, the dam's emergency action plan is yet to be prepared, but it meets guidelines to mitigate potential risks and ensure public safety. The dam's primary purpose of flood risk reduction underscores its importance in water resource management in the region.

Cross Group Dam, with its stone core and soil foundation, serves as a vital infrastructure for flood control and water storage in Broadwater, Nebraska. Supported by the Omaha District of the US Army Corps of Engineers, the dam's design and construction by the Natural Resources Conservation Service reflect collaborative efforts to safeguard the community from potential water-related disasters. As climate change impacts continue to influence water resources, the role of dams like Cross Group Dam becomes increasingly significant in ensuring water security and resilience in the face of changing environmental conditions.
