Coffee Dam, located in Sioux County, Nebraska, along TR-EAST JIM CREEK, stands as a testament to both history and functionality. Built in 1939, this earth dam serves multiple purposes, including fire protection, stock watering, and maintaining a small fish pond. With a height of 14.4 feet and a length of 345 feet, Coffee Dam boasts a storage capacity of 102.7 acre-feet, with a normal storage level of 53.4 acre-feet, covering a surface area of 12 acres and draining an area of 0.82 square miles.

Despite its low hazard potential, Coffee Dam's condition assessment is rated as poor, with the last inspection in July 2018 revealing areas in need of attention. Operated by a private entity, the dam is regulated and inspected by the Nebraska Department of Natural Resources, ensuring compliance with state regulations. As an integral part of the local ecosystem and water resource management, Coffee Dam continues to play a vital role in providing essential services while also facing the challenges of maintaining its structural integrity and safety standards in the face of changing environmental conditions. For water resource and climate enthusiasts, Coffee Dam is a fascinating case study of balancing historical significance with modern-day functionality and maintenance to ensure sustainability for future generations.
