Summary
This earth dam stands at 21 feet high with a hydraulic height of 18 feet and a structural height of 27 feet, providing essential protection to the surrounding area. With a maximum storage capacity of 80 acre-feet and a drainage area of 134.4 square miles, this dam plays a crucial role in managing water levels and mitigating flood risks in the region.
The dam's primary purpose is flood risk reduction, and it has a low hazard potential with a moderate risk assessment rating. Although the condition assessment is not rated and the last inspection was conducted in November 2000, the structure continues to serve its intended function effectively. With a spillway width of 20 feet and uncontrolled spillway type, the dam is designed to handle maximum discharge rates of up to 64 cubic feet per second. Despite not being regulated or inspected by state agencies, the Big Creek-Hurricane Creek B-12 dam remains a vital component of the local water resource management infrastructure.
Overall, Big Creek-Hurricane Creek B-12 is an essential flood risk reduction structure in Carroll, Missouri, contributing to the protection of the surrounding area from potential flooding events. Managed by the Natural Resources Conservation Service, this earth dam has a solid design with stone core types and soil foundations, ensuring its structural integrity. With a storage capacity of 80 acre-feet and a moderate risk assessment rating, this dam plays a crucial role in water resource management and climate resilience efforts 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.
