Summary
Constructed in 1955, this concrete dam stands at a height of 175 feet and spans 2000 feet in length, with a storage capacity of 78,000 acre-feet and a surface area of 3746 acres. With a maximum discharge of 22,000 cubic feet per second and a controlled spillway width of 270 feet, the dam plays a crucial role in managing water resources and generating hydroelectric power in the region.
Managed by the Federal Energy Regulatory Commission, Indian Pond poses a high hazard potential due to its size and location. While its condition assessment is not available, the dam undergoes regular inspections to ensure its structural integrity and compliance with safety regulations. Despite its risk level being classified as very high, the facility has not been modified in recent years and lacks detailed risk management measures.
As a significant feature in the local landscape, Indian Pond serves as a reminder of the intersection between water resource management and climate resilience. Its role in providing renewable energy and regulating water flow underscores the importance of sustainable infrastructure in mitigating the impacts of climate change on our environment.

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.
