Completed in 1946, this dam serves primarily for irrigation purposes with a height of 20 feet and a storage capacity of 98 acre-feet. The dam has a fair condition assessment and a low hazard potential, making it a relatively safe structure.
With a spillway width of 15 feet and an uncontrolled spillway type, N & S has a moderate risk assessment rating. Despite its age, the dam still meets regulatory standards with state jurisdiction, permitting, inspection, and enforcement in place. The last inspection in June 2017 showed the dam to be in fair condition, and emergency action plans are in place in case of any unforeseen events.
Located in a picturesque setting in BIGHORN, N & S stands as a testament to effective water resource management in the region. With Liz Cheney (R) as the Congressional representative overseeing this area, enthusiasts of water resources and climate will find N & S to be a fascinating example of how infrastructure can support agricultural needs while maintaining safety standards in the face of changing environmental conditions.
