Summary
This concrete dam, completed in 1968, stands at a height of 20 feet and has a hydraulic height of 14 feet. With a storage capacity of 99,000 acre-feet and a surface area of 10,016 acres, Churchill plays a crucial role in water resource management in the region.
Despite being classified as having a low hazard potential and being in "not rated" condition as of the last assessment in 2014, Churchill is subject to regular state inspection, permitting, and enforcement to ensure its safety and compliance with regulations. The dam also serves recreational purposes in addition to its primary function of hydroelectric power generation. With its close proximity to the New England District and Congressional District 02 in Maine, Churchill remains an important structure in the local water resource infrastructure.
As a key component of the water management system in the area, Churchill contributes to the sustainable utilization of the Allagash River's resources while providing vital services to the community. With its historical significance and ongoing maintenance, Churchill stands as a testament to the intersection of water resource management, climate resilience, and energy production in the region.

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.
