Troublesome Creek Watershed Dam T- 52a Reservoir Report
Last Updated: December 9, 2025
Troublesome Creek Watershed Dam T-52a, located in Knox City, Missouri, was completed in 2004 by the USDA NRCS to serve primarily as a Flood Risk Reduction structure.

Summary
The earth dam stands at a height of 17 feet, with a hydraulic height of 14 feet and a structural height of 25 feet, offering a maximum storage capacity of 76.9 acre-feet and a normal storage of 20 acre-feet. The dam spans a length of 600 feet and covers a surface area of 4 acres, serving a drainage area of 143 square miles along TR-Troublesome Creek.
Despite being classified as having a low hazard potential, Troublesome Creek Watershed Dam T-52a is deemed to have a moderate risk level. The dam features an uncontrolled spillway with a width of 20 feet and outlet gates that are also uncontrolled. While the dam's condition assessment is currently not rated, it undergoes inspections at a frequency of once per year, with the last inspection conducted in September 2004. The structure's risk management measures, emergency action plan, and inundation maps readiness remain unspecified, suggesting room for improvement in disaster preparedness and response protocols for this vital Flood Risk Reduction infrastructure in the region.

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.
