Summary
Built in 1971, this earth dam stands at a height of 20 feet and a length of 520 feet, with a capacity to store 55 acre-feet of water. The dam's primary purpose is flood risk reduction, but it also caters to fire protection, stock, small fish ponds, and recreational activities.
Managed by a private entity, Lake Mizzou Dam is deemed to have a low hazard potential and a moderate risk assessment. With a spillway width of 33 feet and a maximum discharge capability of 500 cubic feet per second, the dam is equipped to handle varying water levels efficiently. Despite not being state-regulated, the dam plays a critical role in safeguarding the surrounding community from potential flooding events.
While Lake Mizzou Dam's condition assessment is currently not rated, its presence as a protective barrier against floods underscores its importance in maintaining the ecological balance and ensuring the safety of the residents in Waverly, Missouri. As climate change continues to impact water resources, the significance of structures like Lake Mizzou Dam in mitigating environmental risks cannot be overstated.

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.
