Summary
Constructed in 1902, this Earth dam stands at a height of 22 feet and has a storage capacity of 2130 acre-feet. The pond covers a surface area of 137 acres and drains an area of 4 square miles, with a spillway width of 35 feet.
Maintained by the Maine Emergency Management Agency (MEMA), Chases Pond is regulated, inspected, and enforced to ensure its structural integrity and safety. The dam has a significant hazard potential but was last assessed to be in satisfactory condition in 2015. Emergency action plans are in place and updated periodically to meet guidelines in case of any potential risks or emergencies.
Considered a significant water resource for the region, Chases Pond not only provides essential water supply but also serves as a key element in water resource management and climate resilience efforts. With its historical significance and ongoing regulatory oversight, Chases Pond remains a crucial asset in ensuring water security and environmental sustainability in the area.

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.
