Summary
Designed by the USDA NRCS and completed in 1988, this earth dam stands at a height of 22 feet and serves primarily for flood risk reduction along the TR-Troublesome Creek. With a storage capacity of 81 acre-feet and a drainage area of 80 square miles, this dam plays a vital role in managing water flow and protecting the surrounding areas from potential flooding.
Despite its low hazard potential, Troublesome Creek Watershed Dam S-57 has a moderate risk level, signifying the need for proper risk management measures. The dam features an uncontrolled spillway with a width of 30 feet and no outlet gates. While it has not been rated for its current condition, regular inspections and maintenance are essential to ensure its continued functionality and safety. With a surface area of 7 acres and a normal storage capacity of 19 acre-feet, this dam is a key component of the water resource infrastructure in the region.
Located in Nelsonville, Missouri, Troublesome Creek Watershed Dam S-57 is a critical structure in the flood risk reduction efforts of the area. With a stone core and soil foundation, this dam has been serving its purpose effectively for over three decades. As climate change continues to impact water resources, the maintenance and upkeep of such structures become increasingly important to safeguard communities and mitigate potential risks associated with extreme weather 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.
