Summary
Built in 1993 by the USDA NRCS, this earth dam stands at a height of 26.5 feet and has a hydraulic height of 24 feet. With a storage capacity of 134 acre-feet and a drainage area of 153.6 square miles, this dam plays a crucial role in mitigating flood risks in the area along TR-Big Creek.
Despite being classified as a high hazard potential structure, Big Creek-Hurricane Creek S- 12 is currently in "Not Rated" condition. It serves as a vital piece of infrastructure for the local government, designed to protect the surrounding community from potential flooding events. With a spillway width of 24 feet and a maximum discharge of 169 cubic feet per second, this dam is equipped to handle moderate risk factors associated with its location.
The rock foundation and stone core of this dam contribute to its structural integrity, ensuring its effectiveness in flood risk reduction efforts. Although no recent inspection data is available, the USDA NRCS continues to oversee the operations and maintenance of this essential water resource management structure. For water resource and climate enthusiasts, Big Creek-Hurricane Creek S- 12 serves as a prime example of how engineered solutions can help safeguard communities against the impacts of extreme weather events.

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.
