Summary
W. Harding is a privately owned earth dam located in Denver, Missouri, specifically in Worth County. Constructed in 1999 by the USDA NRCS, this dam serves the primary purpose of grade stabilization along the Little Rock Creek. With a height of 25 feet and a hydraulic height of 24 feet, J. W. Harding has a low hazard potential and is rated as having a moderate risk assessment.
The dam has a storage capacity of 23 acre-feet, with a maximum discharge rate of 73 cubic feet per second. The spillway, which is uncontrolled, has a width of 25 feet. Despite its low hazard potential, the dam's condition assessment has not been rated, and there is no emergency action plan (EAP) in place. The surrounding area has a drainage area of 115 acres, with a surface area of 3 acres covered by the dam.
Overall, J. W. Harding serves as a crucial infrastructure for grade stabilization along the Little Rock Creek in Missouri. With its construction completed in 1999 and its low hazard potential, this dam plays a significant role in managing water resources in the area. However, the lack of a condition assessment, emergency action plan, and updated risk management measures may pose potential challenges in ensuring the safety and efficiency of this structure in the face of changing climate conditions.

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.
