Summary
Completed in 1999, this dam stands at a height of 26 feet and has a hydraulic height of 23 feet, with a structural height of 29 feet. With a storage capacity of 149 acre-feet and a drainage area of 19.2 square miles, this dam serves as a critical infrastructure for managing water resources in the region.
The dam has a low hazard potential and is currently not rated for its condition assessment. Despite being uncontrolled, the spillway of the dam has a width of 30 feet to handle a maximum discharge of 220.1 cubic feet per second. While the dam has not been modified in recent years, it is inspected annually to ensure its integrity and functionality. With its moderate risk assessment rating, the Big Creek-Hurricane Creek B-47 dam plays a crucial role in mitigating flood risks and protecting the local community from potential water-related disasters.
For water resource and climate enthusiasts, the Big Creek-Hurricane Creek B-47 dam offers a fascinating case study in sustainable water management practices. From its construction by the USDA NRCS to its ongoing monitoring and maintenance, this dam showcases the importance of strategic infrastructure development in addressing flood risks and safeguarding communities. As climate change continues to impact water resources, understanding the design and performance of dams like B-47 is essential for ensuring resilience in the face of evolving environmental challenges.

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.
