Summary

The dam, which is classified as an Earth dam with a buttress core type, stands at a height of 16 feet and has a hydraulic height of 9 feet. It spans a length of 200 feet and has a storage capacity of 870 acre-feet, with a normal storage level of 330 acre-feet.

The dam, situated on the East Branch of Ware River, is regulated by the Department of Conservation and Recreation in Massachusetts. Despite its high hazard potential and unsatisfactory condition assessment, the dam has not undergone any major modifications in recent years. The last inspection in October 2019 noted the need for improvement, highlighting the importance of regular monitoring and maintenance to ensure the safety and integrity of the structure.

With its location in Worcester County and proximity to a small drainage area of 1.7 square miles, Moulton Pond Dam plays a crucial role in water resource management and flood control in the region. As climate change continues to impact weather patterns and water availability, the maintenance and regulation of dams like Moulton Pond are essential for sustainable water management and protection of downstream communities and ecosystems.

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.
