Summary
This dam stands at a height of 27.4 feet with a hydraulic height of 26 feet and a structural height of 30 feet, providing a storage capacity of 49.1 acre-feet and serving a drainage area of 108.8 square miles. The dam's spillway, which is uncontrolled, has a width of 20 feet, and the maximum discharge capacity is 134.3 cubic feet per second.
With a hazard potential rated as low and a moderate risk assessment score of 3, the condition of Big Creek-Hurricane Creek T-33 is currently not rated. The dam has not been inspected to date, and no emergency action plan (EAP) or inundation maps have been prepared. Despite these gaps in readiness measures, the dam continues to play a vital role in mitigating flood risks in the area, showcasing the importance of ongoing monitoring and maintenance efforts to ensure its effectiveness in protecting the community and environment from potential water resource challenges related to climate variability and 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.
