Summary
Built in 1972 with a primary purpose of recreation, this earth dam boasts a height of 14 feet and a length of 340 feet, containing a maximum storage capacity of 108 acre-feet. Situated on the TR-Lake George river system, the dam is regulated by the New York State Department of Environmental Conservation and undergoes regular inspections to ensure its structural integrity.
Despite its low hazard potential, the Ed Grant Pond Dam plays a vital role in moderating the flow of the TR-Lake George river and mitigating potential risks associated with flooding in the surrounding area. The dam's uncontrolled spillway, with a width of 20 feet, allows for controlled release of excess water during periods of high flow, maintaining the safety and stability of the dam. With a risk assessment rating of moderate (3), the dam is equipped with emergency action plans and contingency measures to address any unforeseen events or emergencies.
As a focal point for water resource and climate enthusiasts, the Ed Grant Pond Dam serves as a reminder of the delicate balance between human intervention and natural forces. Its strategic location and design not only enhance recreational opportunities in the region but also contribute to the overall sustainability and resilience of the local ecosystem. Whether admiring its engineering marvel or appreciating its environmental significance, the Ed Grant Pond Dam stands as a beacon of responsible water management practices in the face of a changing climate.

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.
