Summary
Completed in 1992, this earth dam stands at a height of 24 feet with a hydraulic height of 24 feet and a structural height of 29 feet. With a storage capacity of 200 acre-feet and a drainage area of 130 square miles, this dam plays a crucial role in flood risk reduction in the region.
The primary purpose of Troublesome Creek Watershed Dam T- 81a is flood risk reduction, with additional purposes including fish and wildlife pond enhancement. With a spillway width of 40 feet and a low hazard potential, this dam serves as a key infrastructure for managing water flow in the area. While it has not been rated for its condition, the dam has a moderate risk assessment score of 3, indicating the need for ongoing monitoring and management.
Despite being a locally owned and operated structure, Troublesome Creek Watershed Dam T- 81a falls under the jurisdiction of the Missouri state government. With no state regulation, permitting, inspection, or enforcement in place, it is crucial for the local government to ensure the proper maintenance and upkeep of this essential flood control infrastructure. As a key player in the overall water resource management of the region, this dam serves as a reminder of the importance of effective watershed management practices in mitigating flood risks and ensuring the long-term sustainability of water resources in the area.

Dam Data Reference
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.
