The dam, situated on Stone Man Creek, stands at a height of 28 feet and has a length of 640 feet, providing a storage capacity of 175 acre-feet for fire protection, stock, or small fish ponds. The dam's primary purpose is to serve as a reliable water source for various uses while also contributing to the local ecosystem.
Despite being classified as having a low hazard potential, Stone Man Dam is regulated by the North Dakota State Water Commission (NDSWC) and undergoes regular inspections, with the last one conducted in May 1980. The dam features an uncontrolled spillway with a width of 60 feet, ensuring efficient water release during high-flow events. While the risk assessment for the dam is moderate, there are no documented emergency action plans or inundation maps prepared, highlighting areas for potential improvement in risk management and emergency response protocols.
Water resource and climate enthusiasts interested in the history and technical details of Stone Man Dam will find it to be a fascinating example of early 20th-century infrastructure designed to meet the water needs of the local community. With its earth core and stone foundation, the dam continues to play a crucial role in water storage and management, showcasing the importance of maintaining and monitoring such structures for long-term sustainability in a changing climate.
