Summary
This earth dam stands at a height of 32 feet, with a dam length of 620 feet and a storage capacity of 117 acre-feet. With a low hazard potential and moderate risk assessment rating, this dam serves as a vital infrastructure for managing water resources in Harrison County.
The dam features an uncontrolled spillway with a width of 26 feet, and it is primarily constructed with stone core and soil foundation. Despite not being regulated or inspected by the state, West Fork Big Creek Dam P-32 is an essential part of the local government's flood control measures. With its strategic location and design, this dam plays a crucial role in mitigating potential flood risks and protecting the surrounding area from inundation during heavy rainfall events.
Although the dam is not currently rated for its condition, its emergency action plan status is unknown, highlighting the need for continued monitoring and risk management measures. With the support of the Natural Resources Conservation Service and the local government, West Fork Big Creek Dam P-32 stands as a testament to collaborative efforts in safeguarding water resources and enhancing climate resilience in the region.

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.
