Papio Creek D-18 is a crucial structure located in Douglas County, Nebraska, specifically in Omaha. This dam, completed in 1990 by the USDA NRCS, serves as a flood risk reduction measure for the local community. The earth dam stands at a height of 40 feet and has a storage capacity of 404 acre-feet, with a normal storage level of 81 acre-feet. The dam's primary purpose, aside from flood risk reduction, is categorized as 'Other', indicating its multi-faceted role in water resource management.

Managed by the Nebraska Department of Natural Resources, Papio Creek D-18 is regulated, permitted, inspected, and enforced by state authorities to ensure its functionality and safety. The dam's condition assessment in June 2017 rated it as 'Satisfactory', with a low hazard potential. Despite its importance, the dam has not been modified in recent years and does not fall under the jurisdiction of the US Army Corps of Engineers.

With a drainage area of 1.6 square miles and a maximum discharge of 1503 cubic feet per second, Papio Creek D-18 plays a vital role in mitigating flood risks and protecting the surrounding areas. Its strategic location along the TR-Papio Creek and its satisfactory condition make it a key component of water resource management in the region, highlighting its significance for both water resource and climate enthusiasts in the area.
