The dam, built in 1892 by the USDA NRCS, is a concrete gravity structure standing at 12 feet high and 65 feet long. The lake has a storage capacity of 2,904 acre-feet, covering a surface area of 242 acres and serving a drainage area of 50 square miles.
Despite its age, Big Creek Lake is state regulated, with the DNRC overseeing permitting, inspection, and enforcement. The spillway, with a width of 145 feet, is uncontrolled, and the hazard potential is deemed significant. While the condition assessment is not rated, the emergency action plan was last revised in August 2021, indicating a proactive approach to risk management. With moderate risk identified, the reservoir remains a crucial water resource in the region.
Water resource and climate enthusiasts will be drawn to Big Creek Lake for its historical significance and operational importance in the irrigation sector. Its location in the beautiful Ravalli County, surrounded by the Big Creek stream, adds to its appeal for those interested in sustainable water management practices. As a key feature in the local landscape, the reservoir serves as a testament to the ingenuity of early dam engineers and continues to play a vital role in supporting agricultural activities in the area.
