Summary
This earth dam stands at a height of 29.9 feet with a hydraulic height of 29 feet and a structural height of 32 feet. It has a storage capacity of 154.6 acre-feet and serves the primary purpose of flood risk reduction for the TR-Big Creek watershed, covering a drainage area of 262.4 square miles.
The dam features an uncontrolled spillway with a width of 24 feet and is classified as having a low hazard potential with a moderate risk assessment level. The structure, made of stone core and soil foundation, spans a length of 1014 feet and has a surface area of 6.2 acres. Despite not being state regulated, inspected, or permitted, Big Creek-Hurricane Creek B-6 plays a crucial role in mitigating flood risks for the region, with its condition assessed as "Not Rated" and emergency action plan status undisclosed.
With its strategic location and significant contribution to flood control efforts in the area, Big Creek-Hurricane Creek B-6 stands as a testament to effective water resource management and climate resilience measures. As a key infrastructure project overseen by the Natural Resources Conservation Service and serving the community under local government ownership, this dam serves as a vital asset in safeguarding the region against potential water-related disasters and ensuring the sustainable management of water resources in Missouri.

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.
