Summary
Completed in 1989, this earth dam stands at a height of 24 feet and has a hydraulic height of 23 feet, contributing to the overall safety and protection of the surrounding community. With a primary purpose of flood risk reduction, the dam also serves as a fish and wildlife pond, showcasing its importance in maintaining the local ecosystem.
Covering a drainage area of 768 acres, this dam has a storage capacity of 155 acre-feet and a maximum discharge of 154.5 cubic feet per second. Despite its low hazard potential, the dam is in moderate risk due to its condition assessment being unrated. The spillway type is uncontrolled with a width of 30 feet, ensuring efficient water flow during peak periods. Overall, Troublesome Creek Watershed Dam T- 46 plays a crucial role in safeguarding the community from potential flooding events and supporting the local environment.
Even though the dam has not undergone recent inspections or assessments, its construction and design by the Natural Resources Conservation Service reflect a commitment to ensuring its structural integrity and functionality. The presence of emergency action plans and risk management measures would further enhance the safety of the surrounding area in case of unforeseen events. Troublesome Creek Watershed Dam T- 46 stands as a testament to effective collaboration between local government and federal agencies in addressing water resource management and climate resilience in Missouri's Knox County.

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.
