Summary

With a primary purpose of water supply, this earth dam was completed in 1908 and reaches a height of 45 feet, with a length of 415 feet. The dam has a storage capacity of 30 acre-feet, providing essential water resources for the surrounding area.

Despite its significance, the Frankfort Reservoir Dam is considered to have a significant hazard potential due to its poor condition assessment. The last inspection in 2017 revealed concerns about the dam's safety, prompting a high-risk assessment. With a significant hazard potential, it is essential for the local government and regulatory agencies to prioritize maintenance and potential risk management measures to ensure the safety and continued functionality of this vital water resource structure in the Mohawk River region.

As water resource and climate enthusiasts monitor the state-regulated Frankfort Reservoir Dam, attention to its risk assessment and condition becomes crucial. With a poor condition assessment and a high-risk designation, stakeholders must work together to address any potential hazards and ensure the dam's structural integrity for the preservation of water supply and environmental sustainability in the Herkimer County area.

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.
