Summary

Built in 1945, this concrete dam stands at 15 feet high and spans 110 feet in length. With a storage capacity of 56 acre-feet, Hilton Pond provides a reliable source of water for the surrounding area.

Managed by the local government and regulated by the Maine Emergency Management Agency (MEMA), Hilton Pond is considered to have a low hazard potential. Although the dam's condition is currently not rated, regular inspections are conducted every 12 months to ensure its safety and functionality. Despite its age, Hilton Pond continues to play a crucial role in water resource management and climate resilience efforts in the region.

With its unique design and historical significance, Hilton Pond serves as a prime example of sustainable hydroelectric infrastructure in Maine. As water resource and climate enthusiasts, the data surrounding Hilton Pond sheds light on the importance of maintaining and monitoring dams to ensure their longevity and effectiveness in supporting local communities. As we continue to face challenges related to climate change, Hilton Pond stands as a testament to the intersection of water management, renewable energy, and environmental stewardship.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
