Summary
The dam, completed in 1950, is primarily made of concrete and stands at a height of 7 feet with a length of 50 feet. The reservoir has a storage capacity of 2264 acre-feet, with a normal storage level of 1328 acre-feet and a surface area of 538 acres.
Despite its low hazard potential and the lack of a formal condition assessment, King and Bartlett Lake is regulated by the Maine Emergency Management Agency, with state permitting, inspection, and enforcement in place. The dam's spillway width is 12 feet, and it is situated on the TR-Spencer Stream. There have been no reported modifications to the dam over the years, and emergency action plans and risk assessments are yet to be prepared for this structure.
For water resource and climate enthusiasts, King and Bartlett Lake presents an interesting case study of a privately owned dam with diverse uses and potential risks. With its scenic location and importance in flood risk reduction, fish and wildlife conservation, and recreational activities, this dam serves as a vital resource in the region. Further monitoring and assessment of its condition and risk management measures could enhance its long-term sustainability and resilience in the face of changing climate conditions.

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.
