Summary

The dam, classified as a masonry type, stands at a height of 47 feet and spans 550 feet in length, holding a storage capacity of 170,235 acre-feet. Situated on the Indian River, the dam serves to protect the surrounding area from potential flooding while also offering recreational opportunities for visitors.

Despite its historical significance and vital role in flood control, Indian Lake Stone Dam has been rated as having a high hazard potential and poor condition assessment. The dam is under the regulatory oversight of the New York State Department of Environmental Conservation, with regular inspections and enforcement measures in place to ensure its structural integrity and public safety. The risk of failure is deemed very high, underscoring the importance of ongoing risk management and maintenance efforts to safeguard the community and the environment.

As a key infrastructure asset in Hamilton County, New York, Indian Lake Stone Dam serves as a critical component of the region's water resource management system. With its controlled spillway and significant storage capacity, the dam plays a vital role in mitigating flood risks and ensuring the safety of nearby residents. However, ongoing monitoring and maintenance are essential to address the dam's poor condition assessment and high hazard potential, highlighting the need for proactive risk management measures to protect the surrounding area from potential disasters.

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.
