Summary

This earth dam stands at a height of 30 feet and has a length of 500 feet, creating a reservoir with a normal storage capacity of 32 acre-feet. The dam is situated on the TR-Gleason Branch-Quick Creek and is classified as having a low hazard potential.

Managed by a private owner, Wyatt Lake Dam is not regulated or permitted by the state, but it falls under the jurisdiction of the St. Louis District of the US Army Corps of Engineers. The dam features an uncontrolled spillway with a width of 48 feet and has a maximum discharge capacity of 300 cubic feet per second. Despite its moderate risk assessment rating, the dam's condition is currently not rated, and no emergency action plan has been prepared. For water resource and climate enthusiasts, Wyatt Lake Dam offers a fascinating glimpse into the intersection of human engineering and natural water systems in the heart of Missouri.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
