Summary
This earth dam stands at a height of 39 feet with a length of 790 feet, creating a storage capacity of 128 acre-feet. The dam is situated on the TR-Flat Creek, with a drainage area of 80 square miles, providing a surface area of 11 acres for outdoor activities.
The dam is regulated by the DAM AND RESERVOIR SAFETY PROG in Missouri, ensuring that it meets state inspection and enforcement standards. Despite its low hazard potential, the dam is in satisfactory condition according to the last assessment in 2007. The spillway type is uncontrolled with a width of 20 feet, allowing for a maximum discharge of 570 cubic feet per second. With its moderate risk assessment rating of 3, Qualles Lake Dam remains a vital structure for water resource management and climate resilience in the region.
Overall, Qualles Lake Dam offers a safe and enjoyable recreational experience for visitors, while also serving as a key infrastructure for water storage and management in Monroe County. With its scenic location on TR-Flat Creek and ample storage capacity, the dam plays a crucial role in enhancing the local environment and supporting outdoor activities. As a well-maintained structure with a moderate risk rating, Qualles Lake Dam exemplifies the importance of sustainable water resource management in the face of changing climate conditions.

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.
