West Fork Big Creek Dam P- 23 Reservoir Report
Last Updated: December 16, 2025
West Fork Big Creek Dam P-23, located in Bridgeport, Missouri, was completed in 2001 by the USDA NRCS to primarily serve as a flood risk reduction structure along the Polecat-OS river.

Summary
This earth dam stands at 24.9 feet in height, with a total length of 450 feet and a storage capacity of 50 acre-feet. Despite being uncontrolled, the spillway width of 20 feet ensures that the maximum discharge of 136 cubic feet per second can be managed effectively.
With a low hazard potential and a moderate risk assessment rating, West Fork Big Creek Dam P-23 plays a crucial role in protecting the surrounding area from potential flooding events. The dam has not been inspected since its completion in 2001, and its condition is currently listed as "Not Rated". While it may not be state-regulated or permitted, the dam's design and construction by the Natural Resources Conservation Service highlight the importance of collaborative efforts in managing water resources and mitigating climate-related risks in the region. Enthusiasts interested in water resource management and climate resilience would find West Fork Big Creek Dam P-23 to be a fascinating case study in flood risk reduction infrastructure.

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.
