Summary
Completed in 1974, this dam stands at 24 feet high with a length of 603 feet, providing a storage capacity of 200 acre-feet and covering a surface area of 18 acres. With a low hazard potential and a moderate risk assessment rating of 3, Darrell Callaway serves as a vital resource for water management in the region.
Although not regulated or inspected by state agencies, Darrell Callaway remains an essential infrastructure for irrigation in the area. Its uncontrolled spillway, with a width of 50 feet, ensures proper water flow management during times of excess. The dam's risk management measures and emergency action plan status are currently unreported, highlighting the need for continued monitoring and assessment to maintain its functionality and safety.
Owned and operated by a private entity, Darrell Callaway exemplifies the importance of sustainable water resource management in the face of changing climate conditions. As a key component of the local water infrastructure, this dam plays a crucial role in supporting agricultural activities and ensuring water availability for the community. Its history, design, and purpose underscore the significance of responsible water resource development for the long-term well-being of 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.
