Summary
Constructed in 1996 by the USDA NRCS, this earth dam stands at a height of 24 feet and has a hydraulic height of 21 feet. With a length of 530 feet and a storage capacity of 92 acre-feet, it serves to protect the surrounding area from potential flooding events.
Situated on the TR-Big Creek river, this dam has a low hazard potential and is currently rated as "Not Rated" in terms of condition assessment. Although it does not have outlet gates, the uncontrolled spillway with a width of 20 feet allows for water to safely pass through during times of high discharge. With a drainage area of 239 square miles and a moderate risk assessment rating of 3, this dam plays a crucial role in managing water resources in the region and mitigating flood risks.
Despite its low hazard potential, ongoing monitoring and maintenance of Big Creek-Hurricane Creek B-66 are essential to ensure its continued effectiveness in flood risk reduction. With the involvement of the Natural Resources Conservation Service in its design, this dam is a key infrastructure for water resource and climate enthusiasts to study and appreciate for its role in protecting the local community from potential flooding 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.
