Summary
Built in 1835, this hydroelectric structure stands at 15 feet tall with a length of 86 feet, providing a storage capacity of 1620 acre-feet. The dam serves as a low hazard potential with a moderate risk assessment, overseen by the Federal Energy Regulatory Commission for inspection and regulation.
Despite its age, Mason continues to operate efficiently as a hydroelectric facility, contributing to the region's renewable energy sources. The dam's uncontrolled spillway with a width of 30 feet ensures proper water discharge during peak flow periods, maintaining the structural integrity of the surrounding area. Although the condition assessment is not available, the dam's historical significance and functional purpose highlight its importance in the local water resource management.
With the presence of Mason in the Waldo County landscape, water resource and climate enthusiasts can appreciate the blend of historic craftsmanship and modern energy production techniques. As a privately owned structure, the dam stands as a testament to Maine's commitment to sustainable hydroelectric power generation while maintaining the ecological balance of the Goose River. For those interested in the intersection of historic preservation and renewable energy, Mason serves as a compelling example of innovation and longevity in the water resource sector.

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.
