Summary
This earth dam stands at a height of 26 feet and has a structural height of 28 feet, with a length of 500 feet and a storage capacity of 78 acre-feet. Its spillway, of uncontrolled type, is 20 feet wide, and the dam has a low hazard potential and a moderate risk assessment rating.
Despite not being state-regulated or inspected, West Fork Big Creek Dam B-151 serves as a crucial structure for flood control in the region, with a normal storage capacity of 19 acre-feet and the ability to handle a maximum discharge of 133 cubic feet per second. With its stone core and soil foundation, this dam plays a significant role in mitigating flood risks and protecting the surrounding area from potential inundation. The dam's design and construction by the Natural Resources Conservation Service highlight the importance of sustainable water resource management and climate adaptation efforts in the face of changing weather patterns and increasing flood risks.

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.
