Summary
This beautiful water resource, completed in 1960, serves as a haven for aquatic life while offering recreational opportunities for visitors. With a dam height of 15 feet and a hydraulic height of 12 feet, Grand Lake Stream provides a tranquil setting for fishing, boating, and wildlife observation.
Managed by the Maine State Agency, Grand Lake Stream boasts a normal storage capacity of 120 acre-feet and covers a surface area of 15 acres. Despite its low hazard potential, the condition of the dam is not currently rated, and inspection is carried out on a yearly basis. The dam serves as a vital resource for maintaining the natural ecosystem of Grand Lake and ensuring the safety of the surrounding community in times of emergency.
While the dam's primary purpose is to support fish and wildlife populations, it also contributes to the overall health and sustainability of the region's water resources. With a focus on conservation and environmental protection, Grand Lake Stream stands as a testament to the importance of responsible water management in the face of climate change challenges.

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.
