Summary
Completed in 1960, this reservoir serves as a crucial water supply source for the area, with a storage capacity of 7,860 acre-feet and a surface area of 375 acres. The dam stands at a height of 34 feet and has a maximum discharge capacity of 500 cubic feet per second.
Managed by the local government, the Watson, Harold E, Reservoir is regulated by the state authorities, with inspections and enforcement measures in place to ensure its safety and functionality. Despite having a high hazard potential, the condition assessment of the dam is currently listed as "Not Rated," with the last inspection conducted in September 2013. The reservoir plays a vital role in water resource management in the region, highlighting the importance of maintaining and monitoring its structural integrity.
With its proximity to the Pachet Brook, the Watson, Harold E, Reservoir is a key component of the local water supply infrastructure in Newport County. As climate change continues to impact water resources, reservoirs like this one become even more essential for ensuring a reliable water source for the community. Ongoing risk assessments and management measures are crucial for safeguarding this reservoir and its surrounding environment for future generations of water resource and climate enthusiasts.

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.
