Summary
This concrete dam, with a height of 16 feet and a hydraulic height of 12.5 feet, serves primarily for recreational purposes, providing a serene environment for water enthusiasts to enjoy Flag Brook. With a storage capacity of 62 acre-feet and a surface area of 6.3 acres, the dam offers a picturesque setting for outdoor activities.
Managed by a private owner but regulated by the Department of Conservation and Recreation in Massachusetts, the James Pond Dam has been deemed to have a significant hazard potential, yet its condition assessment in 2016 rated it as satisfactory. Despite its age, the dam has undergone regular inspections every 5 years to ensure its safety and functionality. With a moderate risk assessment and no associated locks or outlet gates, the dam continues to play a vital role in the local water resource management.
As climate and water resource enthusiasts explore the rich history and vital role of the James Pond Dam, its presence as a recreational structure in Worcester County, Massachusetts, highlights the intersection of human ingenuity and natural beauty. With its intricate design, the dam not only provides a serene environment for visitors but also serves as a reminder of the importance of sustainable water management in the face of changing environmental conditions.

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.
