Summary

This earth dam, with a height of 29 feet and a length of 217 feet, holds a maximum storage capacity of 963 acre-feet and a normal storage of 796 acre-feet. The reservoir covers a surface area of 136 acres and is fed by the TR-SPRUCE CREEK, providing essential water resources for the surrounding area.

Maintained by local government authorities and regulated by the NYS DEC, the Klondike Reservoir Dam has a low hazard potential and a moderate risk assessment rating. Despite not being condition-rated, the dam continues to play a crucial role in safeguarding water supply for the community. With a spillway width of 31 feet and a maximum discharge capacity of 1070 cubic feet per second, the dam's uncontrolled spillway ensures efficient water management to prevent overflow during periods of high precipitation.

As a historic structure with a rich legacy of water resource management, the Klondike Reservoir Dam stands as a symbol of resilience and sustainability in the face of changing climate patterns. Its strategic location and operational efficiency highlight the importance of maintaining and upgrading infrastructure to meet the challenges posed by a shifting climate landscape. Enthusiasts of water resources and climate resilience will find the Klondike Reservoir Dam to be a fascinating example of adaptive infrastructure that continues to serve its community with reliability and efficiency.

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.
