Summary
This concrete structure stands at 9 feet high with a hydraulic height of 6 feet, providing a storage capacity of 317 acre-feet. The dam's primary purpose is to generate hydroelectric power, contributing to the region's renewable energy resources.
With a low hazard potential and a condition assessment that is currently not rated, Upper Bartlett plays a crucial role in water resource management in the area. The dam has state jurisdiction and is regulated by MEMA, with state permitting, inspection, and enforcement in place. Even though it is not rated for condition assessment, the dam's operational efficiency and structural integrity are monitored regularly to ensure public safety and environmental sustainability.
As a part of the New England District, Upper Bartlett serves as a key infrastructure for water resource and climate enthusiasts to study and appreciate. Its location in a picturesque setting in York, Maine, adds to its appeal for those interested in exploring the intersection of water management, renewable energy, and environmental conservation efforts.

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.
