Plum Creek 3-2 is a significant earth dam located in Liberty, Nebraska, along TR-Plum Creek. Built in 1969 by the USDA NRCS, this dam serves multiple purposes, including flood risk reduction. With a height of 25 feet and a length of 506 feet, Plum Creek 3-2 has a storage capacity of 69 acre-feet and covers a surface area of 3 acres. Despite its low hazard potential, the dam is currently in poor condition and was last inspected in June 2020.

Managed by the Nebraska Department of Natural Resources, Plum Creek 3-2 is subject to state regulations, inspections, and enforcement. With a drainage area of 0.4 square miles and a maximum discharge of 291 cubic feet per second, this dam plays a crucial role in water resource management in Pawnee County. While there are no associated structures or federal agencies involved in its ownership or funding, Plum Creek 3-2 remains a key feature in the local government's efforts to mitigate flood risks and protect the surrounding community.

As an enthusiast of water resources and climate, the unique characteristics and vital functions of Plum Creek 3-2 make it a noteworthy infrastructure project worth monitoring. With its historical significance, current condition assessment, and ongoing state oversight, this dam exemplifies the intersection of engineering, environmental stewardship, and public safety in managing water resources and addressing the impacts of climate change in Nebraska's Pawnee County.
