Summary
Built in 1904, this concrete gravity dam stands at a height of 27 feet and has a length of 455 feet, providing a storage capacity of 608 acre-feet. With a drainage area of 251 square miles and a maximum discharge of 16,500 cubic feet per second, Forestport plays a crucial role in both hydroelectric power generation and navigation in the region.
Managed by the Federal Energy Regulatory Commission, Forestport has a high hazard potential but overall moderate risk assessment. While the condition assessment is not available, regular inspections are conducted to ensure the dam's safety and functionality. The dam features an uncontrolled spillway with a width of 315 feet and is surrounded by a surface area of 75 acres, serving as a key water resource infrastructure in the area.
Forestport is a significant structure in the region, contributing to both water resource management and climate adaptation efforts. With its historic significance and ongoing operational role in hydroelectric power generation, Forestport stands as a testament to the importance of sustainable water infrastructure in the face of changing climate patterns and increasing water resource demands.

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.
