Summary
Built in 1917, this concrete dam stands at a height of 34 feet and has a storage capacity of 2670 acre-feet. With a surface area of 93 acres and a drainage area of 490 square miles, the structure plays a crucial role in water resource management in Clinton County.
Managed by a public utility, High Falls Intake Structure is under the jurisdiction of the Federal Energy Regulatory Commission (FERC) for regulatory oversight and inspections. Despite its high hazard potential, the condition assessment for this dam is not available, highlighting the need for further evaluation and risk management measures. The structure's primary purpose is hydroelectric power generation, with no spillway present and a maximum discharge capacity of zero.
As a significant feature in the region's water infrastructure, High Falls Intake Structure serves as a reminder of the intersection between water resources and climate considerations. Its historical significance and ongoing operation underscore the importance of proper maintenance and monitoring to ensure the safety and sustainability of this essential resource for the community.

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.
