Summary
The dam, standing at 27 feet high with a hydraulic height of 26 feet, serves multiple purposes including fire protection, stock or small fish pond, fish and wildlife pond, in addition to its flood risk reduction function. With a storage capacity of 125 acre-feet and a drainage area of 420 acres, the dam plays a crucial role in managing water resources in the region.
The dam, situated on Troublesome Creek, has a spillway type of uncontrolled with a width of 20 feet and a length of 450 feet. Despite being rated as having a low hazard potential and a moderate risk assessment, the dam's condition assessment is currently not rated. The last inspection of the dam took place in June 1999, with an inspection frequency of once every year. With its strategic location and design, Troublesome Creek Watershed Dam S- 48 continues to play a vital role in water resource management and flood risk reduction efforts in the area.
In case of emergencies, the dam does not have outlet gates and its Emergency Action Plan (EAP) status is not available. While the dam meets guidelines for risk assessment, the overall risk management measures and inundation maps prepared are not specified. With its impressive track record and capacity to handle water resources effectively, Troublesome Creek Watershed Dam S- 48 stands as a testament to successful collaboration between local government agencies and the USDA NRCS in safeguarding the region against potential flooding events.

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.
