Summary

Built in 1800, this rockfill dam stretches 180 feet in length and stands at a height of 9 feet, offering a storage capacity of 90 acre-feet. With a surface area of 35 acres and a maximum discharge of 550 cubic feet per second, Simmons Pond is a significant water source in Newport County.

Managed by the state regulatory agency DS, Simmons Pond has not been rated for its condition assessment but is considered to have a significant hazard potential. Despite its age, the dam is inspected every five years, with the last inspection conducted in January 2012. While no emergency action plan (EAP) has been prepared for the dam, it meets state permitting and inspection requirements, ensuring its structural integrity and functionality for fish and wildlife conservation as well as recreational activities within the area.

Surrounded by the scenic beauty of Cold Brook, Simmons Pond serves as a vital ecosystem for aquatic life and a popular spot for outdoor enthusiasts. Its strategic location, under the jurisdiction of the state of Rhode Island, highlights the importance of proper management and maintenance to preserve this valuable water resource for generations to come.

Condition Assessment

Satisfactory
No existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
Fair
No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
Poor A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency. Investigations and studies are necessary.
Unsatisfactory
A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
Not Rated
The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Not Available
Dams for which the condition assessment is restricted to approved government users.

Hazard Potential Classification

High
Dams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
Significant
Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environment damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
Low
Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
Undetermined
Dams for which a downstream hazard potential has not been designated or is not provided.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
