Wyoming Upper

About Wyoming Upper

The primary purpose of Wyoming Upper 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 Fish & Wildlife (state). It impounds the Wood River near Hopkinton.

The dam stands 15 feet tall and stretches 310 feet across, creates a reservoir covering 74 acres, has a maximum storage capacity of 444 acre-feet, and collects water from a drainage area of 59 square miles. Completed in 1885, the structure is over a century 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 satisfactory, indicating no existing or potential dam safety deficiencies are recognized. An emergency action plan is in place for this dam.
