Summary
Built in 1930, this Earth dam stands at a height of 20 feet and stretches 145 feet in length, with a storage capacity of 21 acre-feet. Situated along the Ottauquechee River, this reservoir plays a vital role in providing water to the surrounding area, making it a key asset for water resource enthusiasts.
Despite its significant hazard potential and poor condition assessment, Cox Reservoir remains regulated and inspected by the Vermont Department of Environmental Conservation (DEC) to ensure its safety and functionality. The dam's last inspection in July 2013 indicated a need for improvement, highlighting the importance of ongoing maintenance and risk management measures. The reservoir's unique stone core and soil foundation add to its historical and structural significance, attracting climate enthusiasts interested in the intersection of water infrastructure and environmental preservation.
As a critical water supply facility in Windsor County, Cox Reservoir serves as a valuable resource for the local community and a focal point for discussions on water management, climate resilience, and dam safety. Its location along the Ottauquechee River, coupled with its historical significance and regulatory oversight, make it a compelling site for those interested in exploring the intersection of water resources, climate change, and infrastructure development in Vermont.

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.
