Last Updated: March 16, 2026
Trues Pond, located in Liberty, Maine, is a private water resource regulated by the Maine Emergency Management Agency (MEMA).
Summary
This picturesque pond, with a surface area of 173 acres and a drainage area of 26.4 square miles, serves as a vital habitat for fish and wildlife. The dam, constructed in 1870, stands at a height of 18 feet and has a maximum storage capacity of 1175 acre-feet.
With a low hazard potential and a condition assessment that is currently not rated, Trues Pond provides a serene setting for outdoor enthusiasts and nature lovers alike. The dam's primary purpose is listed as "Other," indicating its importance beyond flood control or water supply. While the last inspection date was in October 2015, with an inspection frequency of 12 months, the pond continues to be a valuable resource for the local community and a haven for biodiversity along the St. George River.

Dam Data Reference
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.
