Summary
Designed by USDA NRCS and completed in 1988, this earth dam serves as a flood risk reduction measure along the TR-Troublesome Creek. With a height of 22 feet and a length of 510 feet, the dam has a storage capacity of 85 acre-feet and a drainage area of 300 acres.
This dam, primarily built for flood risk reduction, has a spillway width of 20 feet and is classified as having a low hazard potential. Despite being categorized as "Not Rated" in terms of condition assessment, the risk assessment remains moderate (3). The structure, made of stone core and resting on a soil foundation, poses no immediate threats and has not undergone any recent modifications. The absence of a formal emergency action plan raises concerns about the preparedness for potential emergencies related to the dam.
In conclusion, Troublesome Creek Watershed Dam S-59 stands as a vital infrastructure for flood control in the region. While it currently operates within acceptable risk levels, there is a need for improved monitoring and emergency preparedness to ensure the safety and effectiveness of this critical water resource management facility.

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.
