Woollen Farms Dam, located in Alma, Nebraska, along the TR-Republican River, was completed in 1960 for the primary purpose of flood risk reduction. This privately-owned earth dam stands at a height of 15.3 feet and has a storage capacity of 58.4 acre-feet, with a normal storage level of 29.7 acre-feet. The dam, constructed with a stone core and soil foundation, spans 235 feet in length and covers a surface area of 5.5 acres within a drainage area of 1.21 square miles.

Managed by the Nebraska Department of Natural Resources (NE DNR), Woollen Farms Dam is state-regulated and subject to regular inspections, with the latest assessment conducted in April 2020 indicating a low hazard potential and a condition assessment of "Not Rated." With a history of serving its community by mitigating flood risks along the Republican River, the dam remains an essential infrastructure for water resource management in Harlan County. While it has not undergone any modifications in recent years, the dam continues to play a crucial role in safeguarding the surrounding areas from potential inundation events.

Under the jurisdiction of Congressional District 03 in Nebraska, Woollen Farms Dam benefits from state permitting, inspection, and enforcement measures to ensure its operational integrity and public safety. With its strategic location and design features, this significant earth dam serves as a vital component in the broader network of flood control infrastructure in the region, highlighting the critical role of water resource management in addressing climate-related challenges and protecting communities from the impacts of extreme weather events.
