Summary
This earth dam stands at a height of 24.7 feet and has a structural height of 28 feet, with a maximum storage capacity of 128 acre-feet. With a primary purpose of flood risk reduction, this dam also supports fish and wildlife pond habitats in the area.
The dam's spillway type is uncontrolled with a width of 30 feet, and it has a low hazard potential with a moderate risk assessment rating of 3. While the dam has not been inspected since October 1999, its condition remains unrated. Troublesome Creek Watershed Dam T-123 is owned and operated by the local government and is not regulated by the state. Despite its non-state jurisdiction, this dam plays a crucial role in managing water resources and protecting the surrounding area from potential flooding events.
For water resource and climate enthusiasts, Troublesome Creek Watershed Dam T-123 presents an intriguing case study of a locally owned flood risk reduction structure in Missouri. With its modest dimensions and uncontrolled spillway, this dam highlights the importance of maintaining and inspecting such critical infrastructure to ensure public safety and environmental protection. As climate change continues to impact water resources, understanding the role of dams like T-123 in mitigating flood risks becomes increasingly vital for sustainable water management practices.

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.
