Summary
This privately owned dam, constructed with a buttress core type and a height of 12 feet, serves the purpose of water storage with a capacity of 66 acre-feet. Despite its low hazard potential, the dam is subject to state regulatory oversight by the Department of Conservation and Recreation.
With a normal storage capacity of 55 acre-feet, Stillwater Pond Dam plays a crucial role in managing water resources in Bristol County, Massachusetts. The dam, with a hydraulic height of 10 feet and no spillway, has not been rated for its condition assessment. However, its risk assessment has been deemed high (2), prompting the need for effective risk management measures to ensure the safety and integrity of the structure.
Although the dam has not been inspected recently and lacks an emergency action plan, its significance in maintaining water levels and mitigating flood risks cannot be understated. Climate and water resource enthusiasts will find the unique design and regulatory framework of Stillwater Pond Dam to be of interest, highlighting the importance of infrastructure in managing and safeguarding water 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.
