Summary
The earth dam, completed in 1964, stands at a height of 25 feet and has a storage capacity of 80 acre-feet. The dam, situated on TR-RED OAK CREEK, covers a surface area of 6 acres and serves a drainage area of 155 square miles.
Despite being privately owned, Wagner Lake Dam is not regulated or inspected by the state of Missouri. With a low hazard potential and a condition assessment of "Not Rated," the dam has not been evaluated for its safety and emergency preparedness measures. The dam's emergency action plan status, risk assessment, and inundation maps are all listed as unknown, highlighting potential areas for improvement in terms of risk management and safety protocols.
For water resource and climate enthusiasts, Wagner Lake Dam serves as an intriguing case study of a privately-owned structure with recreational and water supply purposes. The lack of state regulation and inspection raises questions about the safety and emergency preparedness of the dam, emphasizing the importance of proactive risk management in maintaining the integrity of such critical infrastructure. Further research and assessment may be needed to ensure the long-term sustainability and resilience of Wagner Lake Dam in the face of potential environmental 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.
