Summary
Built in 1970, this Earth-type dam stands at a height of 26 feet with a hydraulic height of 21 feet. It has a maximum storage capacity of 29 acre-feet and a normal storage of 17 acre-feet, covering a surface area of 3 acres.
Despite its low hazard potential, Caeser's poor condition assessment in 2017 raises concerns for its long-term reliability. The dam's inspection frequency is set at every 5 years, with the last assessment taking place in April 2017. With a moderate risk rating of 3, there is a need for enhanced risk management measures to ensure the dam's safety and functionality.
Although Caeser has an uncontrolled spillway type with a width of 30 feet, it lacks outlet gates. With the dam located along Caeser Fork, it plays a vital role in protecting the surrounding area from fires and providing water for livestock and small fish ponds. As water resource and climate enthusiasts, monitoring the condition and maintenance of dams like Caeser is crucial for ensuring the sustainability of water resources in the region.

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.
