Summary
This rockfill dam, completed in 1876, stands at a height of 13 feet and has a hydraulic height of 12 feet. With a storage capacity of 1375 acre-feet and a surface area of 147 acres, the dam plays a vital role in providing water to the surrounding areas. Despite its historical significance, Easton Pond South is considered to have a high hazard potential and a poor condition assessment, as of the last inspection in May 2018.
Managed by local government authorities, Easton Pond South is regulated by the Department of Environmental Management and the Coastal Resources Management Council in Rhode Island. The dam on Bailey Brook has a drainage area of 4 square miles and a maximum discharge capacity of 260 cubic feet per second. In the event of an emergency, the dam's Emergency Action Plan, including contacts and guidelines, is yet to be fully prepared and updated. It is critical for water resource and climate enthusiasts to monitor and advocate for the necessary risk management measures to ensure the safety and integrity of Easton Pond South for the community it serves.

Condition Assessment
SatisfactoryNo 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
HighDams 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.
