Summary
Built in 1966 by the USDA NRCS, this earth dam stands at a height of 42 feet and spans 500 feet in length. Designed for flood risk reduction on Barclay Branch, it has a storage capacity of 336 acre-feet and covers a surface area of 16 acres within a drainage area of 3600 acres. With a maximum discharge of 680 cubic feet per second, this dam plays a crucial role in managing water flow and mitigating flood risks in the region.
Managed by the DAM AND RESERVOIR SAFETY PROG in Missouri, Callahan Creek C-1 has a low hazard potential and is currently in satisfactory condition as of its last assessment in 2007. Despite its relatively low risk level, the dam is inspected every 5 years to ensure its structural integrity and functionality. With uncontrolled spillways and no outlet gates, the dam's emergency action plan and risk assessment are deemed moderate. Its risk management measures and inundation maps are yet to be fully prepared, highlighting the importance of ongoing monitoring and maintenance to safeguard against potential hazards.
Overall, Callahan Creek C-1 serves as a vital infrastructure for flood risk reduction in Boone County, Missouri. With its stone core and rock-soil foundations, this earth dam exemplifies the collaborative efforts between local government agencies and the Natural Resources Conservation Service to protect surrounding communities from potential water-related emergencies. As water resource and climate enthusiasts, understanding the significance of dams like Callahan Creek C-1 in managing water flow, mitigating flood risks, and ensuring public safety is crucial for sustainable water management practices in the region.

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.
