Summary

Built in 1959, the dam stands at a height of 22 feet and spans a length of 140 feet, with a storage capacity of 490 acre-feet. It serves as a barrier on the TOWN MEADOW BROOK, providing flood control and water storage for the surrounding area.

The dam is classified as an Earth dam with a Buttress core type and has a spillway that is uncontrolled. With a hazard potential rated as High and a fair condition assessment, regular inspections and maintenance are imperative to ensure its structural integrity and safety. The dam is regulated by the Department of Conservation and Recreation in Massachusetts, with state permitting, inspection, and enforcement in place to monitor its operation and compliance with regulations.

Despite its moderate risk level, Greenville Pond Dam plays a crucial role in managing water resources and mitigating flood risks in the region. As a key infrastructure asset, it highlights the importance of proactive maintenance and monitoring to safeguard against potential hazards and ensure its continued effectiveness in water management and climate resilience efforts.

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.
