Summary
Managed by the USDA NRCS, this earth-type dam stands at a height of 33 feet and has a length of 780 feet, providing a storage capacity of 280 acre-feet. Completed in 1980, it serves as a vital component in controlling the flow of the TR-Callahan Creek, with a drainage area of 134.4 square miles and a maximum discharge capacity of 520 cubic feet per second.
Despite its low hazard potential, the dam at Callahan Creek Watershed B-3 plays a significant role in mitigating flood risks in the region. With a moderate risk assessment rating of 3, it is essential for maintaining the safety and security of the surrounding communities. While not currently rated for its condition, regular inspections and risk management measures are in place to ensure the effectiveness and reliability of this infrastructure in the face of potential emergencies.
For water resource and climate enthusiasts, the Callahan Creek Watershed B-3 offers a fascinating case study in flood risk reduction and dam management. Situated within the St. Louis District, this structure exemplifies the importance of proactive infrastructure development to safeguard communities against natural disasters. As a notable example of collaboration between local government and federal agencies, it serves as a model for sustainable water resource management practices in the face of changing environmental conditions.

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.
