Summary
Built in 2002 by the USDA NRCS, this earth dam stands at a height of 29 feet and spans a length of 390 feet, with a maximum storage capacity of 42 acre-feet. The dam's primary source agency is the state of Missouri, and it is situated on the Polecat River in Harrison County.
With a low hazard potential and moderate risk assessment rating, West Fork Big Creek Dam P-22 plays a crucial role in managing the water resources of the region. The dam features an uncontrolled spillway with a width of 20 feet and serves a drainage area of 330 square miles. Despite its age, the dam has not been rated for condition assessment, highlighting the need for regular inspections and maintenance to ensure its continued effectiveness in flood risk reduction.
Although the dam has not been state-regulated or permitted, it remains a key piece of infrastructure for the community's safety and well-being. With its strategic location and design, West Fork Big Creek Dam P-22 stands as a testament to the importance of proactive water resource management in mitigating the impacts of climate change and safeguarding against potential flooding events.

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.
