Summary

With a height of 16 feet and a hydraulic height of 12 feet, the dam serves multiple purposes including fire protection, stock or small fish pond, flood risk reduction, and recreation. The pond has a storage capacity of 1822 acre-feet, with a normal storage level of 1212 acre-feet and a surface area of 433 acres, providing a tranquil oasis for water resource and climate enthusiasts to explore.

Managed by the state regulatory agency MEMA, Bear Pond is classified as a low hazard potential structure with a condition assessment of "Not Rated." The dam has not been modified over the years and was last inspected in June 2014. Despite its age, the dam continues to serve its primary purpose of flood risk reduction effectively. Visitors can enjoy the scenic beauty of Bear Pond while appreciating the engineering feat of the historic concrete dam that has stood the test of time.

Located in Androscoggin County, Bear Pond's tranquil waters offer a haven for wildlife and a recreational oasis for locals and tourists alike. With its rich history dating back to the early 19th century, the dam at Bear Pond stands as a testament to the importance of sustainable water resource management and climate resilience in the face of changing environmental conditions. Whether you're interested in exploring the engineering marvel of the dam or simply seeking a peaceful retreat in nature, Bear Pond is a must-visit destination for water resource and climate enthusiasts looking to connect with the natural world.

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.
