Summary
The primary purpose of this earth dam, standing at a height of 21 feet with a hydraulic height of 18 feet, is to provide protection against flooding along the TR-Big Creek. With a storage capacity of 159 acre-feet, the dam covers a surface area of 4.1 acres and serves a drainage area of 140.8 square miles.
Despite its low hazard potential, the Big Creek-Hurricane Creek S- 18 dam has not been rated for its condition assessment. The spillway, which is uncontrolled and 24 feet wide, helps manage maximum discharge up to 164 cubic feet per second. The dam's risk assessment is categorized as moderate (3), indicating the need for ongoing monitoring and maintenance to ensure its effectiveness in flood risk reduction. With no associated structures and no state jurisdiction or regulation, this dam plays a crucial role in safeguarding the surrounding area from potential flooding events.
Overall, Big Creek-Hurricane Creek S- 18 is a significant infrastructure project that demonstrates the collaboration between local government and the USDA NRCS in enhancing water resource management and climate resilience. As a key component in the flood risk reduction strategy for the region, this earth dam serves as a vital safeguard against potential flooding and underscores the importance of proactive measures in mitigating climate-related risks.

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.
