Summary

Built in 1992 by the USDA NRCS, this dam primarily serves the purpose of flood risk reduction, with a height of 26 feet and a hydraulic height of 24 feet. The dam has a structural height of 29 feet and a length of 652 feet, with a storage capacity of 159 acre-feet and a drainage area of 115.2 square miles.

Despite being rated as having a low hazard potential, the dam has a moderate risk assessment score of 3. With a spillway width of 30 feet and uncontrolled spillway type, the dam has not been inspected since November 2000. The condition assessment of the dam is currently marked as 'Not Rated', suggesting a need for further evaluation and potential maintenance. For water resource and climate enthusiasts, Big Creek-Hurricane Creek B- 27 presents an opportunity to study the impact of dams on flood risk reduction in the region and the importance of regular inspections and maintenance to ensure public safety and water resource management.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
