Summary

Completed in 1954, this gravity dam serves primarily for recreational purposes, offering a serene retreat for water resource and climate enthusiasts alike. With a height of 16 feet and a hydraulic height of 13 feet, the dam provides a storage capacity of 175 acre-feet, with a normal storage level of 117 acre-feet.

Managed by a private owner and regulated by the Department of Conservation and Recreation, Pelton Reservoir Dam boasts a low hazard potential and fair condition assessment. The dam spans 260 feet in length and overlooks a tributary of North Brook, blending seamlessly into the picturesque landscape of the surrounding area. Despite its uncontrolled spillway type, the dam has implemented risk management measures to ensure the safety and security of the community.

With an inspection frequency of 10 years and a moderate risk assessment rating of 3, Pelton Reservoir Dam remains a vital part of the local infrastructure. Ensuring compliance with state regulations and maintaining its structural integrity, the dam continues to serve as a valuable resource for water conservation efforts in the region. As a symbol of sustainable water management practices, Pelton Reservoir Dam stands as a beacon of environmental stewardship in the heart of Massachusetts.

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.
