Goose Pasture Tarn

About Goose Pasture Tarn

The primary purpose of Goose Pasture Tarn is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by Town Of Breckenridge (laura Lynch) (local government). It impounds the Blue River near Breckenridge.

The dam stands 71 feet tall and stretches 550 feet across, creates a reservoir covering 68 acres, has a maximum storage capacity of 2,026 acre-feet, and collects water from a drainage area of 42 square miles. Completed in 1965, 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. Its condition is rated unsatisfactory, indicating serious safety deficiencies exist that require immediate attention or remedial action. An emergency action plan is in place for this dam. The most recent inspection on record was 04/27/2022.

At 71 feet, this dam is taller than 96% of all dams in the United States.
