Summary
This earth dam stands at a height of 21 feet and has a structural height of 27 feet, with a length of 530 feet. With a maximum storage capacity of 51 acre-feet and a drainage area of 100 acres, the dam plays a critical role in controlling the flow of Hawkins Branch and protecting the surrounding area from potential flooding.
Despite being classified as having a low hazard potential, Troublesome Creek Watershed Dam T-122 is considered to have a moderate risk level. The dam is equipped with an uncontrolled spillway, 20 feet wide, to manage excess water flow. However, with no outlet gates and a condition assessment that is currently not rated, there is room for improvement in terms of inspection and maintenance. The last inspection was conducted in September 1999, highlighting the need for regular monitoring and upkeep to ensure the dam's effectiveness in flood risk reduction.
As a vital infrastructure for the local community in Knox City, Troublesome Creek Watershed Dam T-122 serves multiple purposes beyond flood risk reduction, including fire protection, stock or small fish pond, and enhancing fish and wildlife habitats. With its strategic placement and design by the Natural Resources Conservation Service, this dam is a valuable asset for water resource and climate enthusiasts interested in sustainable watershed management and protection.

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.
