Summary
This buttress dam stands at a height of 11.25 feet with a hydraulic height of 6 feet, serving a primary purpose that is not specified in the available data. With a storage capacity of 20.6 acre-feet, the dam poses a significant hazard potential and is rated as being in fair condition as of the last assessment in April 2017.
Located in Bristol County, Massachusetts, Grays Mill Pond Dam plays a crucial role in managing water resources in the area. Despite its fair condition, the dam's risk assessment is moderate, indicating the need for ongoing monitoring and maintenance to mitigate potential hazards. The dam's inspection frequency is set at every 5 years, emphasizing the importance of regular assessments to ensure its stability and safety for the surrounding community and ecosystem.
Climate and water resource enthusiasts will find Grays Mill Pond Dam an intriguing subject for further study, given its unique design and significance in the local landscape. As a privately owned and state-regulated structure, the dam serves as a focal point for understanding the intersection of human infrastructure with natural water systems, highlighting the need for responsible management and conservation efforts to adapt to changing climate 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.
