Built in 1954 by USDA NRCS, this dam serves multiple purposes including fire protection, stock water supply, and as a small fish pond. With a height of 25 feet and a length of 289 feet, Stewart has a storage capacity of 77 acre-feet and covers a drainage area of 3.91 square miles.
Managed by the Montana Department of Natural Resources and Conservation (DNRC), Stewart is classified as having low hazard potential and a moderate risk assessment score of 3. Although the dam's condition is currently not rated, it undergoes state-regulated inspections, enforcement, and permitting to ensure its structural integrity and operational safety. The spillway is uncontrolled with a width of 50 feet, and the dam is situated on TR-Dug Out Coulee, a tributary in the area.
Despite its relatively low hazard potential, Stewart plays a crucial role in providing water resources for fire protection and livestock in the Loma area. With its historical significance dating back to the 1950s, this dam showcases the importance of sustainable water management practices in the context of changing climate patterns and evolving environmental regulations.
