Plum Creek 3-B is a local government-owned dam located in Pawnee, Nebraska, designed by USDA NRCS to primarily address flood risk reduction in the area. Completed in 1966, this earth-type dam stands at a height of 26 feet, with a structural height of 31 feet and a length of 480 feet. It has a storage capacity of 114 acre-feet and serves a drainage area of 0.6 square miles along the TR-PLUM CREEK river.

Managed by the Nebraska Department of Natural Resources, Plum Creek 3-B has a low hazard potential and is assessed to be in satisfactory condition as of the last inspection in April 2017. The dam has a spillway width and number of locks unspecified, with regular inspections conducted every 5 years to ensure its continued safety and functionality. The dam's emergency action plan status, risk assessment, and management measures are yet to be determined, indicating a potential area for improvement in future assessments.

Overall, Plum Creek 3-B plays a crucial role in mitigating flood risks in the region, with its strategic location and design contributing to the protection of surrounding areas from potential inundation. As climate change continues to impact water resources and weather patterns, the maintenance and monitoring of dams like Plum Creek 3-B become increasingly important to safeguard communities and infrastructure against the threats of extreme weather events.
