Summary
The dam is primarily used for flood risk reduction, with additional purposes including fire protection, stock, fish and wildlife pond management. This earth dam stands at a height of 31 feet and has a hydraulic height of 30 feet, with a storage capacity of 136.3 acre-feet and a surface area of 7 acres. The dam is situated on the TR-Locust Creek, within the Rock Island District, and is regulated by the state of Missouri.
Despite being classified as having a low hazard potential, Upper Locust Creek W-76 is deemed to have a moderate risk level, with a maximum discharge capacity of 174.9 cubic feet per second. The spillway is uncontrolled, with a width of 30 feet, and the dam features stone core types on a soil foundation. The structure has not been assessed for condition and does not have an emergency action plan in place. Its location in Putnam County, Missouri, highlights its importance in managing water resources and climate-related risks in the region.

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.
