Summary
The dam stands at a height of 12 feet with a hydraulic height of 8 feet, offering a storage capacity of 18 acre-feet. Despite its fair condition assessment as of September 2016, the dam poses a significant hazard potential and is subject to regular state inspection and enforcement by the Department of Conservation and Recreation.
The dam features an uncontrolled spillway type and a surface area of 2 acres, serving as a popular spot for leisure activities in the Plympton area. While it lacks associated structures and has no federal agency involvement, Winnetuxet Road Pond Dam remains under state regulation and jurisdiction, ensuring its compliance with safety standards. With a moderate risk assessment rating, the dam's risk management measures and emergency action plan readiness are yet to be fully detailed, calling for continued monitoring and evaluation to mitigate potential hazards.
Water resource and climate enthusiasts interested in Winnetuxet Road Pond Dam can appreciate its role in providing recreational opportunities while recognizing the need for ongoing assessment and maintenance to ensure public safety and environmental stewardship. The dam's location along the Winnetuxet River adds to its ecological significance, highlighting the importance of sustainable management practices in preserving water resources and adapting to changing climate conditions.

Dam Data Reference
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.
