Summary
It serves multiple purposes, including flood risk reduction, hydroelectric power generation, recreation, and water supply. The dam stands at a structural height of 200 feet and has a hydraulic height of 157 feet, with a storage capacity of 1,706,000 acre-feet and a surface area of 27,700 acres.
The dam poses a high hazard potential and is regularly monitored and maintained by the US Army Corps of Engineers to manage flood risks. Emergency action plans are in place, and the dam undergoes regular inspections to ensure its structural integrity. The Corps works closely with local emergency managers and the public to raise awareness and preparedness for potential dam-related emergencies. Despite the risks associated with dam operations, the Corps continues to prioritize safety and risk management to protect downstream communities and the surrounding environment.
Overall, Dale Hollow Dam remains a vital infrastructure for water resource management and climate resilience in the region. With its multiple functions and strategic location on the Obey River, the dam plays a crucial role in mitigating flood risks, providing clean energy, and supporting recreational activities. The ongoing efforts and proactive measures by the US Army Corps of Engineers ensure the safety and sustainability of this important water resource infrastructure for the benefit of the local community and beyond.

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.
