Lower North River # 80, also known as Union Springs Dam, is a vital flood risk reduction structure located in Rockingham, Virginia. Owned by the local government and regulated by the Department of Conservation and Recreation, this earth dam stands at a height of 81.7 feet and has a storage capacity of 1345 acre-feet to manage the floodwaters of Union Springs Run.

Constructed by USDA NRCS, Lower North River # 80 plays a crucial role in protecting the surrounding area from potential hazards, as it has been assessed as having a high hazard potential yet remains in satisfactory condition. With a drainage area of 5.2 square miles and a normal storage capacity of 462 acre-feet, this dam continues to serve its primary purpose of flood risk reduction effectively.

The last inspection in April 2018 confirmed its structural integrity, and with an established inspection frequency, the dam is well-maintained to ensure its reliability in the face of potential emergencies. For water resource and climate enthusiasts, Lower North River # 80 stands as a testament to sustainable infrastructure management in safeguarding communities against the impacts of extreme weather events.
