Summary
Designed by the USDA NRCS and completed in 2004, this structure serves the primary purpose of flood risk reduction along the TR-Big Creek. With a height of 24.4 feet and a hydraulic height of 17 feet, the dam has a storage capacity of 51.8 acre-feet and a maximum discharge rate of 103.9 cubic feet per second.
The dam, constructed with stone core and soil foundation, spans 760 feet in length and covers a surface area of 1.3 acres. Despite its low hazard potential and moderate risk assessment, the condition of the dam is currently not rated. It operates an uncontrolled spillway with a width of 20 feet and no outlet gates. The structure has not undergone any modifications since its completion, and the last inspection took place in November 2004.
For water resource and climate enthusiasts, the Big Creek-Hurricane Creek B- 50 presents an intriguing case study in flood risk management and infrastructure resilience. As part of the broader efforts to mitigate the impacts of extreme weather events, understanding the design, function, and maintenance of such dams is crucial. With its location in a region prone to flooding, this dam plays a vital role in protecting the surrounding areas and communities from potential water-related disasters.

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.
