About Erie

The primary purpose of Erie is water supply. The dam stores water for municipal, industrial, or agricultural use, helping ensure a reliable supply for the surrounding area. The dam is owned by Town Of Erie (local government). It impounds the Boulder Creek-os near Erie.

The dam stands 19 feet tall and stretches 2,330 feet across, creates a reservoir covering 28 acres, and has a maximum storage capacity of 421 acre-feet. Completed in 1935, the structure is well-established, with more than 75 years of service.

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 fair — the dam has minor deficiencies that are being addressed or do not pose an immediate safety threat. An emergency action plan is in place for this dam. The most recent inspection on record was 09/26/2022.
