Summary
The dam, designed by USDA NRCS, serves primarily for flood risk reduction along the TR-Little Creek. It is classified as an earth-type dam with a height of 33 feet and a length of 430 feet, providing a storage capacity of 115 acre-feet.
With a low hazard potential and a moderate risk assessment rating, West Fork Big Creek Dam B-123 plays a crucial role in mitigating potential flooding in the region. The dam features an uncontrolled spillway with a width of 30 feet and has not been rated for its condition assessment. Despite not being regulated by the state, the dam serves as an important infrastructure for managing water resources in the area.
West Fork Big Creek Dam B-123 stands as a testament to the collaborative efforts between the local government and the Natural Resources Conservation Service in safeguarding the community against flood risks. While its emergency action plan and risk management measures are not explicitly outlined, the dam's presence helps maintain the safety and resilience of the region's water resources and surrounding environment. As a focal point for water resource and climate enthusiasts, this dam represents a significant piece of infrastructure in the ongoing effort to address the challenges posed by changing weather patterns and water management needs.

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.
