Lake Riley

About Lake Riley

The primary purpose of Lake Riley is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by Waco Oil & Gas Company (private). It impounds the Murphy Creek near Weston.

The dam stands 28 feet tall and stretches 250 feet across, creates a reservoir covering 8 acres, has a maximum storage capacity of 93 acre-feet, and collects water from a drainage area of 0 square miles. Completed in 1948, 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. Notably, no emergency action plan is currently on file for this high-hazard dam. The most recent inspection on record was 04/15/2015. That was 10 years ago — unusually long for a high-hazard dam, which typically requires more frequent inspections.
