Summary

This timber crib dam, completed in 1962, stands at a height of 10 feet and boasts a storage capacity of 3555 acre-feet, with a normal storage level of 2370 acre-feet. The lake covers a surface area of 949 acres and has a drainage area of 15 square miles, making it an essential resource for the local ecosystem.

With its low hazard potential and not yet rated condition assessment, Pleasant River Lake remains a safe and enjoyable destination for water enthusiasts and climate advocates alike. While the dam has not been recently inspected, it is regularly maintained by state regulatory agencies to ensure its structural integrity and compliance with safety standards. The lake's spillway, measuring 60 feet wide, provides an important outlet for excess water, further enhancing its environmental sustainability.

As one of the many water resources in the New England District, Pleasant River Lake offers a tranquil escape for visitors seeking recreational activities such as fishing, wildlife observation, and boating. Nestled in the beautiful Maine countryside, this reservoir serves as a vital hub for outdoor enthusiasts and serves as a reminder of the importance of responsible water resource management in the face of climate change challenges.

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.
