Summary
2, located in Croghan, New York, is a privately owned earth dam that serves the primary purpose of hydroelectric power generation on the Beaver River. Built in 1925, this multi-arch dam stands at a height of 10 feet and has a length of 270 feet, with a storage capacity of 1058 acre-feet. Despite being regulated by the Federal Energy Regulatory Commission, the dam has a low hazard potential and is classified as having a high risk level.
While the dam does not have a spillway, it is equipped with outlet gates and is inspected by the Federal Energy Regulatory Commission every three years. With a drainage area of 267 square miles and a surface area of 145 acres, High Falls - Dike No. 2 plays a crucial role in the local water resource management system. Although its condition assessment is currently not available, the dam's risk level is closely monitored to ensure the safety of the surrounding area.
For water resource and climate enthusiasts, High Falls - Dike No. 2 represents a fascinating intersection of historical infrastructure, hydroelectric power generation, and environmental risk management. As a key component of the Beaver River watershed, this dam showcases the delicate balance between harnessing water resources for energy production and safeguarding against potential hazards. Its location in Lewis County, New York, underlines the importance of sustainable water management practices in mitigating the impacts of climate change on our infrastructure and communities.

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.
