Plum Creek 4-G, located in Pawnee, Nebraska, is a crucial earth dam constructed in 1963 by the USDA NRCS to address flood risk reduction in the region. With a height of 30 feet and a length of 674 feet, this dam serves to protect the surrounding area from potential flooding events, utilizing a stone core and soil foundation for structural integrity. The dam has a storage capacity of 121 acre-feet, with a normal storage level of 17 acre-feet, covering a surface area of 9 acres and draining a 0.5 square mile watershed.

Managed by the local government and regulated by the Nebraska Department of Natural Resources, Plum Creek 4-G undergoes regular inspections and enforcement to ensure its functionality and safety.
