Summary
This earth dam stands at a height of 23.5 feet and has a structural height of 27 feet, with a length of 820 feet. It serves the primary purpose of flood risk reduction along the East Fork Big Creek, offering a storage capacity of 145.1 acre-feet and a maximum discharge capacity of 174.5 cubic feet per second.
With a low hazard potential and a moderate risk assessment rating, West Fork Big Creek Dam B-176 plays a crucial role in managing water resources in the region. The dam features an uncontrolled spillway and other controlled outlet gates, ensuring proper water flow regulation during flood events. Despite not being state-regulated, the dam contributes to the overall water management strategy of the area, providing essential protection against potential flooding and safeguarding nearby communities like PATTONSBURG.
As a significant infrastructure project constructed by the Natural Resources Conservation Service, West Fork Big Creek Dam B-176 showcases the importance of proactive flood risk reduction measures in mitigating the impact of extreme weather events. Its strategic location, design, and operational features highlight the collaborative efforts between local government entities and federal agencies to enhance water resource management and climate resilience in Missouri.

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.
