Summary
The dam's primary purpose is flood risk reduction along the TR-Big Creek, with a hydraulic height of 22 feet and a structural height of 32 feet. It has a maximum storage capacity of 78 acre-feet and serves a drainage area of 284.8 square miles, with a low hazard potential rating.
This 542-foot-long dam with a spillway width of 20 feet is designed to handle a maximum discharge of 103 cubic feet per second. Despite not having a state regulatory agency overseeing its operations, the dam is considered to have a moderate risk level. The surrounding area covers 7.9 acres with a normal storage capacity of 22 acre-feet. Emergency action plans have not been prepared, and the condition assessment is currently not rated. The dam's risk management measures and inundation maps status are also not specified.
With its stone core and soil foundation, the Big Creek-Hurricane Creek M-12 dam plays a crucial role in managing flood risks in the region. Water resource and climate enthusiasts can appreciate the engineering behind this structure, designed to protect the local community from potential inundation events. As the dam continues to serve its flood risk reduction purpose, ongoing monitoring and maintenance will be essential to ensure its long-term effectiveness and safety.

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.
