Summary

Completed in 1949, this rockfill dam stands at a height of 71 feet and has a maximum storage capacity of 6000 acre-feet. The dam's primary purpose is to provide water supply to the surrounding area, with a normal storage capacity of 4900 acre-feet and a surface area of 966 acres.

Managed by the Department of Conservation and Recreation in Massachusetts, Cleveland Brook Reservoir Dam is state-regulated and subject to regular inspections to ensure its structural integrity and safety. With a high hazard potential and a moderate risk assessment rating, the dam has been deemed to be in satisfactory condition as of the last assessment in November 2016. Despite its age, the dam continues to play a crucial role in the management of water resources in the region, highlighting the importance of ongoing monitoring and maintenance efforts to safeguard its functionality.

Climate and water resource enthusiasts can appreciate the role of Cleveland Brook Reservoir Dam in securing a reliable water supply for the local community while also recognizing the need for proactive risk management and emergency preparedness measures. As a gravity and rockfill dam on the Cleveland Brook, this structure exemplifies the intersection of engineering, environmental conservation, and public safety, underscoring the intricate balance required to maintain critical infrastructure in the face of changing climate conditions and increasing demands on water resources.

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.
