Summary
Branch Meduxnekeag River. Built primarily for hydroelectric purposes, this concrete dam stands at a height of 8 feet and spans 150 feet in length, with a storage capacity of 50 acre-feet. The dam also serves other purposes such as fish and wildlife pond creation and recreational activities, making it a multifaceted resource in the region.
Despite its low hazard potential, South Meduxnekeag has not been rated for its condition. However, it undergoes regular inspections every 12 months to ensure its structural integrity and safety standards are maintained. The dam's emergency action plan status, risk assessment, and risk management measures are currently unreported, highlighting a need for further evaluation and preparedness in the face of potential challenges related to water resource management and climate variability.
As a key infrastructure for water resource management in the region, South Meduxnekeag plays a crucial role in maintaining water levels, supporting wildlife habitats, and providing recreational opportunities. With its presence along the Meduxnekeag River, the dam serves as a valuable asset for both environmental conservation and sustainable energy production, highlighting the importance of ongoing monitoring and maintenance efforts to ensure its long-term functionality and resilience in the face of changing climate conditions.

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.
