About Haystack Dam
The primary purpose of Haystack Dam is irrigation. The dam stores and diverts water for agricultural irrigation, supporting farming operations in the surrounding area. The dam is owned by Bureau Of Reclamation (federal). It impounds the Haystack Creek Os near Madras.
The dam stands 105 feet tall and stretches 1,200 feet across, creates a reservoir covering 280 acres, has a maximum storage capacity of 7,350 acre-feet, and collects water from a drainage area of 10 square miles. Completed in 1957, the structure is well into its service life at over 50 years old.
This dam carries a high hazard potential classification, which means that a failure or uncontrolled release of water would likely cause loss of human life. This classification reflects the consequences of failure, not the likelihood — it indicates that people live or work in the area downstream. An emergency action plan is in place for this dam. The most recent inspection on record was 03/23/2022.
At 105 feet, this dam is taller than 98% of all dams in the United States.
