Summary

The dam stands at a height of 14 feet and has a storage capacity of 13,347 acre-feet, making it a significant resource for the region. With a normal storage capacity of 8,967 acre-feet and a surface area of 1,690 acres, Moose Pond Storage plays a crucial role in providing water for various uses including fire protection, stock watering, and supporting fish and wildlife in the area.

Managed by the local government and regulated by the Maine Emergency Management Agency (MEMA), Moose Pond Storage is subject to regular inspections to ensure its structural integrity and safety. Despite being classified as having a significant hazard potential, the dam is currently assessed to be in fair condition as of the last inspection in 2015. With a spillway width of 42 feet and a drainage area of 26 square miles, the dam is equipped to handle potential high discharges and protect downstream areas from flooding.

As a key component of the water supply infrastructure in the region, Moose Pond Storage serves as a vital resource for both human and ecological needs. With its strategic location along Moose Pond Brook and its significant storage capacity, the dam plays a crucial role in maintaining water availability for various purposes while also ensuring the safety of surrounding communities through regular inspections and maintenance protocols.

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.
