Summary
With a dam height of 24 feet and a length of 893 feet, it has a storage capacity of 1800 acre-feet and serves as a vital source of renewable energy in the region. Managed by the Federal Energy Regulatory Commission, Jay plays a crucial role in water resource management and climate action efforts.
Despite being classified as having a low hazard potential, Jay undergoes regular inspections every three years to ensure its structural integrity and safety. With a moderate risk assessment rating of 3, the dam is considered to be in satisfactory condition. Emergency action plans are in place, although details on their preparation and adherence to guidelines remain unclear. Overall, Jay serves as a key example of sustainable energy generation and water resource management in Maine, contributing to the region's environmental and economic well-being.
As a historic concrete dam with a gravity design, Jay represents a harmonious blend of traditional engineering and modern environmental stewardship. Its location on the Androscoggin River not only provides clean energy but also supports wildlife habitats and recreational activities. With ongoing risk management measures and a commitment to safety, Jay stands as a testament to the importance of balancing water resource utilization with environmental conservation in the face of climate challenges.

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.
