Summary
Completed in 2003, this earth dam stands at a height of 24.4 feet with a hydraulic height of 24 feet and a structural height of 27 feet. With a storage capacity of 63 acre-feet and a normal storage of 17 acre-feet, this dam plays a crucial role in managing water flow and mitigating potential flooding in the region.
The dam, situated on TR-Troublesome Creek, serves as a valuable asset for the community of Steffenville, Missouri, ensuring the protection of surrounding areas from potential disasters. With a low hazard potential and a moderate risk assessment rating, Troublesome Creek Watershed Dam S- 91 is a reassuring presence for residents and businesses in the vicinity. Even though the condition assessment is currently not rated, regular inspections and maintenance are in place to uphold the structural integrity and functionality of this essential flood risk reduction infrastructure.
Managed by the local government and with no state regulation in place, Troublesome Creek Watershed Dam S- 91 stands as a testament to effective collaboration between various agencies to safeguard the environment and inhabitants from the impacts of extreme weather events. The uncontrolled spillway, outlet gates, and stone core foundation further highlight the engineering excellence behind this critical structure. As climate change continues to pose challenges for water resources management, the significance of dams like S- 91 in maintaining ecological balance and community safety cannot be overstated.

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.
