Summary
Lawrence, New York. Built in 1914, this concrete gravity dam stands at 12 feet tall and spans 211 feet in length, with a storage capacity of 240 acre-feet. The dam is situated on the Raquette River and is regulated by the Federal Energy Regulatory Commission, with inspections conducted by the same agency to ensure its safe operation.
With a low hazard potential and a moderate risk assessment rating, Yaleville poses minimal risk to surrounding areas. The dam features an uncontrolled spillway with a width of 147 feet and is equipped with multiple outlet gates for water release. While the condition assessment is not available, the dam has a regular inspection frequency of 3 years, with the last inspection conducted in August 2019. Despite not being state-regulated, the dam is under the jurisdiction of the state and has a private owner responsible for its maintenance and operation.
Yaleville serves as a vital source of hydroelectric power in the region, contributing to the overall energy production while also providing water storage for various purposes. The dam's location in Yaleville, New York, highlights its importance in the local water resource management system. With its historical significance and continued operation, Yaleville remains a key feature in the region's water infrastructure, showcasing the intersection of modern technology and environmental stewardship in the management of natural resources.

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.
