Summary
Completed in 1926, this earth dam stands at a height of 19 feet and has a length of 1100 feet, with a storage capacity of 90,000 acre-feet. Situated on the Great Chazy River, the dam's spillway type is uncontrolled, with a width of 39 feet. Despite its significant role in the region, the dam's condition assessment is rated as poor, with a high hazard potential, indicating the need for immediate attention and maintenance.
The dam's inspection frequency is set at every two years, with the last inspection conducted in August 2019. The risk assessment for Chazy Lake Dam is classified as moderate, with a DSAC (Dam Safety Action Classification) of 3. The emergency action plan (EAP) for the dam was last revised in October 2009, and updates to emergency contacts and inundation maps are pending. With the dam's critical role in water management and recreation, ongoing risk management measures and maintenance efforts are essential to ensure the safety and sustainability of this important infrastructure in the region.
In the realm of water resource and climate enthusiasts, Chazy Lake Dam presents a fascinating case study of the intersection between human infrastructure and natural water systems. As discussions surrounding dam safety, risk assessment, and emergency preparedness continue to evolve, the challenges and opportunities associated with managing and maintaining structures like Chazy Lake Dam provide valuable insights into the complexities of water resource management in the face of changing environmental conditions and increasing demands for water supply and recreational activities.

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.
