Summary
This earth dam stands at a height of 23 feet, with a hydraulic height of 22 feet and a structural height of 35 feet. It spans a length of 650 feet and has a storage capacity of 146 acre-feet. Despite its low hazard potential, the dam has not been rated for its condition and was last inspected in 1999.
Constructed by the USDA NRCS, this dam on Cottey Creek plays a crucial role in protecting the surrounding area from potential flooding. Its spillway type is uncontrolled with a width of 30 feet, and it is designed to handle a maximum discharge of 174 cubic feet per second. While the dam has not undergone any modifications since its completion, it is essential for local government agencies to ensure regular inspections and maintenance to uphold its effectiveness in flood risk reduction.
For water resource and climate enthusiasts, Troublesome Creek Watershed Dam T-58 serves as a notable example of infrastructure designed to mitigate the impacts of extreme weather events. With a moderate risk assessment score of 3, there is a need for continued monitoring and potentially updating emergency action plans to ensure the safety and functionality of the dam. As a vital component of the local watershed, this dam underscores the importance of proactive management and investment in sustainable water resource infrastructure.

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.
