Summary
Built in 1967, this Earth dam stands at 31 feet tall and spans a length of 3100 feet, with a storage capacity of 2800 acre-feet. The primary purposes of Josephine are debris control, hydroelectric power generation, and irrigation, serving the local community while contributing to the region's water resource management.
Managed by the Maine Emergency Management Agency (MEMA), Josephine is subject to state regulation, permitting, inspection, and enforcement to ensure its safety and compliance with guidelines. Despite its high hazard potential, the dam is currently assessed as being in fair condition as of the last inspection in May 2019. With a drainage area of 5.6 square miles and a surface area of 220 acres, Josephine plays a crucial role in water management and energy production in Aroostook County, Maine.
As a vital infrastructure in the region, Josephine's presence underscores the intersection of water resource management and climate considerations. With its hydroelectric capabilities and irrigation functions, the dam embodies the importance of sustainable water usage and renewable energy generation in a changing climate landscape. Its role in balancing water supply, energy production, and environmental stewardship highlights the complex challenges and opportunities in managing water resources for a resilient future.

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.
