Legacy Dam, located in Douglas County, Nebraska, was completed in 1968 by the USDA NRCS and stands at a height of 37 feet, with a structural height of 45 feet. This earth dam on TR-Box Elder Creek serves primarily for flood risk reduction and other purposes, with a normal storage capacity of 80 acre-feet. Despite its high hazard potential, the dam is deemed to be in satisfactory condition as of the last assessment in October 2020.

Managed by a private owner, Legacy Dam is regulated by the Nebraska Department of Natural Resources, with state permitting, inspection, and enforcement in place. The dam's location in Omaha, along with its close proximity to the Kansas City District of the US Army Corps of Engineers, underscores its significance in water resource management. With a drainage area of 0.04 square miles and a maximum discharge of 9 cubic feet per second, Legacy Dam plays a crucial role in protecting the surrounding community from potential flooding events.

Given its critical role in flood risk reduction and the high hazard potential it poses, Legacy Dam remains a focal point for water resource and climate enthusiasts. With its satisfactory condition and state regulatory oversight, the dam continues to be a vital infrastructure for water management in the region, showcasing the importance of effective dam maintenance and monitoring practices in safeguarding communities from potential water-related disasters.
