Summary
The dam has a height of 25 feet, a length of 680 feet, and a storage capacity of 22 acre-feet. Its primary purpose is flood risk reduction, but it also serves as a fish and wildlife pond and is used for grade stabilization. The dam is classified as low hazard potential with a moderate risk assessment rating.
Managed by the Natural Resources Conservation Service, Lonnie Quick has not been rated for its condition assessment. Despite its low hazard potential, the dam does not have an Emergency Action Plan prepared, and its inspection frequency is reported as 0. The spillway type for the dam is uncontrolled, with a width of 10 feet. Although the dam has not been modified since its completion, it lacks outlet gates and associated structures.
In the event of an emergency, the lack of an EAP and updated emergency contacts raises concerns about the dam's preparedness. However, with its moderate risk assessment rating, Lonnie Quick serves as a valuable resource for flood risk reduction and ecological preservation in the Ray County area of Missouri.

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.
