Summary

Built in 2001 by USDA NRCS, this dam stands at a height of 28 feet and has a hydraulic height of 25 feet, with a total length of 700 feet. Its primary purpose is flood risk reduction, with a storage capacity of 141 acre-feet and a drainage area of 209.92 square miles.

With a spillway width of 34 feet, this dam has a low hazard potential and is currently rated as "Not Rated" in terms of condition assessment. Despite its age, it has not undergone any modifications since its completion. The risk assessment for Big Creek-Hurricane Creek M-7 is moderate (3), indicating a potential for moderate consequences in the event of failure. However, it meets regulatory guidelines and is regularly inspected to ensure its structural integrity and safety.

Overall, Big Creek-Hurricane Creek M-7 serves as a crucial infrastructure for flood risk management in the area, providing protection to the surrounding community and downstream areas. Its construction by the Natural Resources Conservation Service highlights the importance of sustainable water resource management and climate resilience in mitigating the impacts of extreme weather events. As a key component of the local government's flood control strategy, this dam plays a vital role in safeguarding the region against potential flooding risks.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
