Summary

Built in 1882, this historic pond has a dam height of 20 feet and a length of 115 feet, providing a storage capacity of 58 acre-feet. The pond covers a surface area of 17 acres and is fed by Long Creek, making it an important habitat for fish and wildlife in the area.

Managed by the Maine Emergency Management Agency, Clark's Pond is regulated, permitted, inspected, and enforced by state authorities to ensure its safety and functionality. Despite having a low hazard potential, the dam's condition has not been rated since July 2014. The pond's spillway width of 63 feet and emergency action plan status are currently unreported, suggesting the need for further assessment and risk management measures to protect surrounding communities and infrastructure in the event of a potential breach.

Overall, Clark's Pond stands as a vital water resource for both aquatic species and recreational activities in the region. With its rich history and ecological significance, efforts to maintain and monitor the dam's condition are essential for safeguarding the pond's integrity and resilience in the face of changing climate conditions and potential hazards.

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.
