Summary
Completed in 2004, this earth dam stands at 26 feet in height and spans 500 feet in length, providing a storage capacity of 114.9 acre-feet and serving multiple purposes such as fire protection, stock or small fish pond, fish and wildlife pond, and flood risk reduction.
Situated on the TR-LOCUST CREEK, this structure has a low hazard potential and a moderate risk assessment rating. With a normal storage capacity of 33.5 acre-feet and a surface area of 6 acres, Upper Locust Creek W-179 plays a crucial role in managing water resources in the area. Despite not being regulated by the state or having a state inspection and enforcement mechanism, this dam serves as a valuable asset for the community and wildlife in the region.
Managed by the Rock Island District and with Congressman Sam Graves as the representative, Upper Locust Creek W-179 highlights the importance of sustainable water resource management and climate resilience. With its uncontrolled spillway and outlet gates, this dam showcases the collaboration between local government and federal agencies in mitigating flood risks and enhancing the overall water infrastructure 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.
