About Emerald Lake Dam

The primary purpose of Emerald Lake Dam is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by Emerald Lakes Property Owners Association (private). It impounds the Weirs Creek.

The dam stands 29 feet tall and stretches 875 feet across, creates a reservoir covering 27 acres, has a maximum storage capacity of 439 acre-feet, and collects water from a drainage area of 1 square miles. Completed in 1955, 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 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 06/16/2021.
