Managed by the Nebraska Department of Natural Resources, this structure serves multiple purposes including flood risk reduction. Constructed in 1984 by the USDA NRCS, the dam stands at a height of 29 feet with a hydraulic height of 28 feet and a structural height of 33 feet. With a storage capacity of 117 acre-feet and a drainage area of 0.5 square miles, Long Branch P-8 plays a critical role in water resource management in the region.
Situated on the TR-Long Br Big Nemaha River, Long Branch P-8 has a low hazard potential and is deemed to be in satisfactory condition based on the last inspection conducted in June 2016. With a maximum discharge capacity of 225 cubic feet per second, the dam helps regulate water flow and reduce the risk of downstream flooding. Its stone core and soil foundation contribute to its structural integrity, while its location and design aim to minimize environmental impact and maximize water storage efficiency. As a key component of the state's regulatory framework, Long Branch P-8 highlights the importance of sustainable water management practices in the face of changing climate patterns.
