Summary
Constructed in 1999 by the USDA NRCS, this earth dam stands at 18 feet high and spans 550 feet in length, with a storage capacity of 61 acre-feet and a drainage area of 64 square miles. The dam has a low hazard potential and a moderate risk assessment rating, making it a crucial infrastructure for the local community.
Managed by the Natural Resources Conservation Service, Big Creek-Hurricane Creek B- 46 features an uncontrolled spillway with a width of 20 feet. Despite its age, the dam has not undergone a condition assessment and is currently rated as "not rated." The last inspection took place in November 2000, with an inspection frequency of once per year. With its strategic location and design features, this dam plays a vital role in safeguarding the surrounding area from potential flood events.
Although not regulated by the state and with no state jurisdiction, Big Creek-Hurricane Creek B- 46 serves as a critical piece of infrastructure in flood risk management within the region. With its stone core and soil foundation, this dam highlights the collaborative efforts between federal agencies and local government to address water resource challenges. As a focal point for water resource and climate enthusiasts, this dam exemplifies the importance of proactive measures in addressing flood risk and ensuring community resilience in the face of changing environmental conditions.

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.
