Summary
Pleasant Pond Dam, located in Boylston, Massachusetts, is a privately owned structure designed by the USDA NRCS and completed in 1967 for the primary purpose of irrigation. This earth dam, with a height of 13 feet and a length of 800 feet, impounds water from a tributary of French Brook, creating a storage capacity of 81 acre-feet. The dam is regulated by the Department of Conservation and Recreation in Massachusetts and has a significant hazard potential with a satisfactory condition assessment as of the last inspection in March 2017.
The Mt. Pleasant Pond Dam serves as a vital resource for water management in the area, providing irrigation for agricultural purposes. With a drainage area of 0.86 square miles, the dam helps to control water flow and storage, contributing to the sustainability of the surrounding ecosystem. Despite its significant hazard potential, the dam's condition assessment remains satisfactory, indicating that proper maintenance and inspection protocols are in place to ensure its integrity and safety.
As a key component of the local water infrastructure, the Mt. Pleasant Pond Dam plays a crucial role in water resource management in Worcester County, Massachusetts. Its design, construction, and regulatory oversight by the Department of Conservation and Recreation highlight the importance of proper dam maintenance and operation for both water supply and environmental protection. Climate and water resource enthusiasts can appreciate the significance of this structure in balancing human needs with the conservation of natural resources in the region.

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.
