Summary
Completed in 1935, this Earth dam stands at a height of 15 feet and spans a length of 1244 feet, with a storage capacity of 165 acre-feet. The dam is equipped with Tainter and Vertical Lift gates for water control, and its hazard potential is classified as low.
Managed by the Federal Energy Regulatory Commission, the Korty Diversion plays a crucial role in water resource management and energy production in the region. The structure has not undergone recent condition assessments, but regular inspections are conducted every three years to ensure its safety and functionality. Despite its age, the dam continues to fulfill its intended purposes efficiently, serving both agricultural and energy needs in the area.
With a risk assessment rating of 2 (high), the Korty Diversion is closely monitored for any potential hazards or risks that may arise. While the dam has not experienced significant modifications in recent years, its operational procedures and emergency preparedness protocols are regularly reviewed to meet safety guidelines. As a key component of the local water infrastructure, the Korty Diversion remains a vital resource for the community and a testament to the enduring importance of sustainable water management practices in the face of changing climate conditions.

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.
