Summary
Built in 1994 by USDA NRCS, this earth-type dam stands at a height of 21.6 feet and serves the primary purpose of flood risk reduction along the West Fork Big Creek. With a normal storage capacity of 22 acre-feet and a maximum storage of 87 acre-feet, this dam plays a crucial role in managing water flow in the region.
Despite being classified as low hazard potential, the dam has a moderate risk assessment score of 3. It features an uncontrolled spillway with a width of 127 feet and has not been inspected since September 1994. The dam has not been rated for its condition assessment, and there is no Emergency Action Plan (EAP) prepared for it. While the risk management measures and guidelines for the dam remain unspecified, its role in flood risk reduction underscores its importance in safeguarding the surrounding area from potential water-related disasters.
As an essential infrastructure for water resource management in the region, West Fork Big Creek Dam B-107 presents a fascinating case study for climate and water resource enthusiasts. Its construction, design, and operational details offer valuable insights into the role of dams in mitigating flood risks and ensuring water security for local communities. Further research and monitoring of this dam could provide valuable data for understanding its performance and resilience in the face of changing climate conditions.

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.
