Summary
This earth dam, designed by USDA NRCS, stands at a height of 25 feet and has a structural height of 35 feet. With a normal storage capacity of 48 acre-feet and a maximum storage of 189 acre-feet, this dam serves as a crucial structure in protecting the surrounding area from potential flooding.
The dam spans 480 feet in length and has a spillway width of 40 feet to manage excess water during high-flow events. Despite being classified as having a low hazard potential, the dam's risk assessment is moderate, indicating the importance of ongoing monitoring and maintenance. Troublesome Creek Watershed Dam S-47 is operated by the local government and has not been subject to state regulation, inspection, or enforcement.
With a drainage area of 440 acres and a surface area of 17 acres, this dam plays a significant role in managing water resources in the region. Its association with fire protection, stock, small fish ponds, fish and wildlife habitat, in addition to flood risk reduction, showcases the multi-faceted benefits it provides to the community. Overall, Troublesome Creek Watershed Dam S-47 stands as a vital infrastructure for safeguarding against flooding and ensuring sustainable water management for years to come.

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.
