Summary
With a height of 9 feet and a surface area of 128 acres, this dam on Quiggle Brook has a storage capacity of 600 acre-feet and serves as a small fish pond. The dam has a low hazard potential and has not been rated for its condition as of the last assessment in 2011.
Managed by the Maine Emergency Management Agency (MEMA), Fish Pond is regulated, permitted, inspected, and enforced by the state. While the dam itself is in good condition and poses a low risk, its emergency action plan (EAP) status, inundation maps, and risk assessment measures are not currently available. The dam's last inspection was conducted in May 2018, with a frequency of 12 months for routine checks.
Overall, Fish Pond is a historic water resource structure that provides both recreational opportunities and fire protection benefits to the surrounding area. As climate change continues to impact water resources, it will be essential for regulators and owners to ensure the dam's continued safety and functionality for years to come.

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.
