Summary

Completed in 1976, this rockfill dam serves as a critical flood risk reduction measure along the CAESAR CREEK river. With a structural height of 180 feet and a hydraulic height of 168 feet, the dam has a storage capacity of 242,200 acre-feet and a normal storage of 102,000 acre-feet.

Managed by the US Army Corps of Engineers, Caesar Creek Dam plays a crucial role in reducing the risk of flooding for the surrounding areas. The dam also serves purposes such as recreation and water supply, covering a surface area of 2,830 acres. Regular inspections and maintenance are conducted to ensure the dam's structural integrity, with emergency protocols in place to address any potential risks associated with high hazard potential. With a commitment to risk management and public safety, the USACE continually works to mitigate any potential threats and ensure the dam operates effectively in all conditions.

Overall, Caesar Creek Dam stands as a vital infrastructure piece in the region, highlighting the importance of proactive risk management and maintenance practices for water resource and climate enthusiasts. Its role in flood risk reduction and water management showcases the critical need for sustainable infrastructure to address the challenges posed by changing environmental conditions.

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.
