Summary
Completed in 1979, this earth dam stands at a height of 54 feet and spans a length of 450 feet, with a storage capacity of 1000 acre-feet and a drainage area of 980 acres. Despite its high hazard potential, the dam is currently assessed as being in satisfactory condition, last inspected in May 2015.
Managed by the local government and regulated by the Dam and Reservoir Safety Program, the Callahan Creek C-2 dam plays a crucial role in flood risk reduction in the region. With a spillway width of 100 feet and a maximum discharge capacity of 4138 cubic feet per second, the dam provides a necessary safeguard for the surrounding community of McBaine. Despite its moderate risk assessment, the dam's structure and operations are closely monitored to ensure the safety and security of the area.
As a key component of the state's dam and reservoir safety protocols, the Callahan Creek C-2 dam serves as a model for effective water resource management and climate resilience. With its strategic location and robust design, this earth dam stands as a testament to the collaborative efforts of local and federal agencies in safeguarding communities against the impacts of extreme weather events.

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.
