About Wigley Lake Dam

The primary purpose of Wigley Lake Dam is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by Wigley Family Trust (private). It impounds the Little Noonday Creek.

The dam stands 26 feet tall and stretches 357 feet across, creates a reservoir covering 7 acres, and has a maximum storage capacity of 83 acre-feet.

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 poor, meaning the dam has recognized safety deficiencies that require remediation to address risks. An emergency action plan is in place for this dam. The most recent inspection on record was 02/10/2016. That was 10 years ago — unusually long for a high-hazard dam, which typically requires more frequent inspections.
