Summary
Constructed in 1996 by the USDA NRCS, this earth dam stands at 30 feet high with a hydraulic height of 28 feet. With a storage capacity of 147 acre-feet and a drainage area of 320 acres, this dam plays a crucial role in managing floodwaters in the region.
The dam features an uncontrolled spillway with a width of 40 feet and a length of 690 feet, serving its primary purpose of flood risk reduction. Despite being classified as having a low hazard potential, the structure has a moderate risk rating of 3. While the condition assessment is currently marked as "Not Rated," the dam is regularly monitored for any potential risks or maintenance needs. As a key component in the local government's flood management efforts, Big Creek-Hurricane Creek M-9 serves as a vital infrastructure for safeguarding the surrounding communities from potential flooding events.
Given its strategic location and design, this dam is an essential asset in the region's water resource management and climate resilience efforts. With its significant storage capacity and hydraulic capabilities, Big Creek-Hurricane Creek M-9 stands as a testament to the collaborative efforts between government agencies and the local community in addressing flood risks and ensuring the safety and well-being of residents in Carroll County, 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.
