Curran Lower Reservoir

About Curran Lower Reservoir

The primary purpose of Curran Lower Reservoir is fish and wildlife pond. The dam creates habitat for fish and wildlife, supporting local ecosystems and potentially serving conservation goals. The dam is owned by Ri Dem Parks & Recreation (state). It impounds the Clarke Brook near Cranston.

The dam stands 17 feet tall and stretches 1,300 feet across, creates a reservoir covering 20 acres, has a maximum storage capacity of 250 acre-feet, and collects water from a drainage area of 1 square miles. Completed in 1950, 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 poor, meaning the dam has recognized safety deficiencies that require remediation to address risks. An emergency action plan is in place for this dam.
