Summary
Completed in 2000, this earth dam stands at a height of 28 feet and has a storage capacity of 67.1 acre-feet, with a normal storage level of 13.2 acre-feet. The dam, made of stone core and soil foundation, spans 471 feet in length and covers a surface area of 16 acres within a drainage area of 214 square miles.
With a low hazard potential and a moderate risk assessment rating, West Fork Big Creek Dam B-184 features an uncontrolled spillway type with a width of 25 feet and other controlled outlet gates. Despite not being state regulated or inspected, the dam has not undergone a condition assessment and is currently rated as "Not Rated." The risk management measures, emergency preparedness plans, and inundation maps for the dam have not been updated or finalized, indicating potential areas for improvement in addressing any future emergencies or risk mitigation strategies.
Overall, West Fork Big Creek Dam B-184 serves as a significant infrastructure for flood risk reduction in the area, with its construction overseen by the Natural Resources Conservation Service. As an earth dam with a stone core, this structure plays a crucial role in managing water resources along the West Fork Big Creek and highlights the importance of maintaining and updating emergency response plans to ensure the safety and security of the surrounding communities in the face of potential climate-related 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.
