Ralston Dam, located in Jefferson County, Colorado, is a vital structure managed by a public utility for water supply purposes. Built in 1937, this earth-type dam stands at 180 feet in height and has a storage capacity of 15,900 acre-feet, serving the Ralston Creek watershed. With a spillway width of 347 feet and a maximum discharge of 37,500 cubic feet per second, the dam plays a crucial role in flood control and water management for the region.

Despite its satisfactory condition assessment as of September 2020, Ralston Dam poses a high hazard potential due to its location and the volume of water it holds. However, risk assessments indicate a moderate risk level with appropriate risk management measures in place. The dam is state-regulated and subject to regular inspections, ensuring its continued safety and reliability for the surrounding community. With its strategic position in the water infrastructure of Arvada and the surrounding areas, Ralston Dam stands as a key asset for water resource and climate enthusiasts interested in sustainable water management practices in Colorado.
