Summary

Lawrence County, New York, is home to a significant hydroelectric dam on the Raquette River. This gravity dam, completed in 1928, stands at a height of 17 feet and spans a length of 292.5 feet, with a storage capacity of 264 acre-feet and a maximum discharge of 19,000 cubic feet per second. The dam serves as a vital source of hydroelectric power, contributing to the renewable energy landscape in the region.

Managed by the Federal Energy Regulatory Commission, the Raymondville dam has a low hazard potential and a very high risk assessment rating, highlighting the importance of proper risk management measures. While the condition assessment of the dam is currently not available, regular inspections are conducted every three years to ensure its structural integrity. Despite its age, the dam continues to play a crucial role in water resource management and climate action efforts in the area.

Raymondville's hydroelectric dam not only showcases the historical significance of hydroelectric power generation but also underscores the ongoing need for sustainable energy sources in combating climate change. With its controlled spillway system and efficient operation, the dam stands as a testament to the intersection of water resource management, renewable energy production, and environmental stewardship in the region.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
