Summary
This earth dam stands at 32 feet tall with a hydraulic height of 27 feet and a length of 550 feet. It serves the primary purpose of flood risk reduction along the TR-Big Creek, with a storage capacity of 142 acre-feet and a drainage area of 230.4 square miles.
With a low hazard potential and a moderate risk assessment rating of 3, Big Creek-Hurricane Creek T-9 is an important structure in managing water resources in the area. The dam has a spillway width of 30 feet and a surface area of 5.6 acres, providing essential protection to the surrounding community from potential flooding. While the condition assessment is currently not rated, regular inspections are conducted to ensure the dam's safety and effectiveness in flood control.
Owned by the local government and situated in an area represented by Sam Graves (R), this structure plays a vital role in safeguarding the region against flood risks. As a significant component in the water resource management system, its construction and design by the Natural Resources Conservation Service underscores the commitment to sustainable water infrastructure development in the state of 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.
