Summary
Completed in 1990, this earth dam stands at 29 feet high and spans 670 feet in length. With a storage capacity of 126 acre-feet and a drainage area of 38.4 square miles, the dam plays a crucial role in protecting the surrounding area from potential flooding events.
This dam, primarily owned by the local government, serves the purpose of flood risk reduction and is classified as having a low hazard potential with a moderate risk assessment rating. While it has not been inspected since November 2000, the structure remains in a not-rated condition. The spillway, with a width of 34 feet, functions as an uncontrolled overflow system in case of high water levels, further showcasing the dam's strategic design and operational capabilities in managing water flow effectively.
Despite not being regulated by the state, the Big Creek-Hurricane Creek B-9 dam continues to stand as a valuable asset in safeguarding the region from potential inundation. With its stone core and soil foundation, this earth dam represents a key component in the local water resource management infrastructure, demonstrating a commitment to enhancing resilience against flooding events in the area.

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.
