Summary
Built in 1973, this private earth dam stands at a height of 30 feet and has a storage capacity of 80 acre-feet. With a primary purpose of debris control, the dam plays a vital role in managing water resources in the area.
Despite its low hazard potential, Mccoy-Waits Lake Dam has not been rated for its condition assessment. However, it continues to serve its purpose effectively, with a normal storage capacity of 38 acre-feet and a drainage area of 230 square miles. The dam's location in Corning, Missouri, under the ownership of a private entity, highlights the importance of private involvement in water resource management and climate resilience efforts.
As water resource and climate enthusiasts continue to monitor and assess the condition of dams like Mccoy-Waits Lake Dam, it is important to recognize the critical role these structures play in safeguarding communities and ecosystems. With ongoing advancements in dam safety and management practices, there is a growing emphasis on ensuring the resilience and effectiveness of such infrastructure in the face of changing climate conditions and water resource challenges.

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.
