Summary

Completed in 1941, this structure serves as a vital component for hydroelectric purposes on the West Fork Tuckasegee River. With a storage capacity of 67,100 acre-feet and a surface area of 1,462 acres, the dam plays a crucial role in water resource management in the region.

Managed by the Federal Energy Regulatory Commission, the Glenville Saddle Dike has a high hazard potential and is subject to regular inspections to ensure its integrity and safety. Despite not having a spillway, the dam is equipped with operational features to mitigate risks and respond to emergencies effectively. With a risk assessment rating of 2 (high), the structure is closely monitored to implement necessary risk management measures.

As a significant infrastructure for hydroelectric power generation, the Glenville Saddle Dike stands as a testament to the intersection of water resource management and climate resilience. Its strategic location and operational efficiency underscore the importance of sustainable practices in maintaining a balance between energy production and environmental conservation in the region.

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.
