Summary
This earth dam stands at a height of 21 feet and spans 512 feet, providing a storage capacity of 52 acre-feet. Situated on TR- WOLF CREEK, the dam serves a primary purpose of flood risk reduction and is regulated by the Iowa Department of Natural Resources.
With a low hazard potential and a moderate risk assessment rating, West Fork Big Cr Wtrshd Site W-30 plays a crucial role in managing water resources in the area. The dam features an uncontrolled spillway with a width of 17700 feet, ensuring efficient water discharge during heavy rain events. Despite its importance in flood control, the dam's condition assessment is currently not rated, highlighting the need for ongoing inspection and maintenance.
Owned by the local government and located in the city of STATE OF MISSOURI, West Fork Big Cr Wtrshd Site W-30 demonstrates a commitment to water resource management and climate resilience. As a key piece of infrastructure in the region, this dam contributes to the overall safety and sustainability of the surrounding community, showcasing the collaboration between federal and state agencies in safeguarding water resources for future generations.

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.
