Tom Frost is a local government-owned dam located in Broomfield, Colorado, designed by the USDA NRCS to serve as a flood risk reduction structure along the Big Dry Creek-OS. Completed in 1951, this earth-type dam stands at a height of 12 feet and stretches 1068 feet in length. With a storage capacity of 160 acre-feet, it also serves the dual purpose of creating a fish and wildlife pond in addition to flood risk reduction.

Despite its relatively low hazard potential and moderate risk assessment, Tom Frost has not been rated for its current condition as of the last inspection conducted in 1998. The dam is equipped with an uncontrolled spillway, measuring 133 feet in width, to manage excess water flow during periods of high discharge. While the structure has not been modified in recent years, it is subject to regular state inspection, permitting, and enforcement to ensure its continued functionality and safety in mitigating flood risks in the area.

Enthusiasts of water resources and climate will find Tom Frost to be an intriguing example of a locally owned dam with historical significance in the region. Its purposeful design by the USDA NRCS, ongoing state regulation, and unique combination of flood risk reduction and ecological benefits make it a noteworthy feature in the landscape of water management and conservation efforts in Colorado.
