About Ross Canyon Dam

The primary purpose of Ross Canyon Dam is flood risk reduction. The dam is designed to control downstream flooding by temporarily storing excess water during storms and releasing it at a controlled rate. The dam is owned by Pathfinder Irrigation District (local government). It impounds the Tr-moffat Drain near Bayard.

The dam stands 50 feet tall and stretches 1,047 feet across, creates a reservoir covering 3 acres, has a maximum storage capacity of 468 acre-feet, and collects water from a drainage area of 3 square miles. Completed in 1960, the structure is well into its service life at over 50 years old.

This dam has a significant hazard potential classification, meaning that a failure could cause significant economic damage — flooding roads, bridges, or property downstream — but is not expected to result in loss of life. Its condition is rated satisfactory, indicating no existing or potential dam safety deficiencies are recognized. The most recent inspection on record was 03/24/2023.

At 50 feet, this dam is taller than 93% of dams nationwide.
