Built in 1979 by HKM Associates for the USDA Forest Service, this Earth dam stands at 21 feet high and spans 344 feet in length, with a storage capacity of 154 acre-feet. The dam's primary purpose is irrigation, serving the surrounding area with a normal storage capacity of 101 acre-feet. Despite its low hazard potential and "Very High" risk assessment rating, Maney has not been formally rated for its condition or undergone recent inspection as of October 2015.
This remote yet crucial water resource infrastructure is managed and funded by the Forest Service and serves as a vital component for irrigation in the region. While the dam's spillway type is listed as "Controlled" and its outlet gates are equipped with a slide (sluice gate), there are no associated structures or locks present. Even though Maney's risk assessment is categorized as "Very High (1)" and it lacks formal emergency action plans or condition assessments, the dam continues to provide essential water management services for Jefferson County, Montana. For water resource and climate enthusiasts, Maney represents a unique intersection of environmental stewardship, water management, and infrastructure development in the American West.
