Summary
Completed in 2001, this earth dam stands at a height of 31 feet with a structural height of 36 feet and a length of 500 feet. With a storage capacity of 160 acre-feet and a drainage area of 90 acres, the dam plays a crucial role in protecting the surrounding areas from potential flooding events.
Managed by the local government, Troublesome Creek Watershed Dam S-98 primarily serves the purpose of flood risk reduction while also supporting fire protection and providing a habitat for fish and wildlife. With a low hazard potential and a moderate risk assessment rating, the dam has not been rated for its condition assessment. While it does not have any associated structures or federal agency involvement, the dam's uncontrolled spillway and outlet gates ensure efficient water management during high discharge events. With its strategic location and design, Troublesome Creek Watershed Dam S-98 stands as a testament to effective water resource management and climate resilience efforts in the region.
Overall, Troublesome Creek Watershed Dam S-98 exemplifies the importance of sustainable infrastructure for managing water resources and mitigating climate-related risks. As part of the broader conservation efforts along the Troublesome Creek, this dam serves as a key asset in safeguarding the local community from potential flood events. With its strategic design, low hazard potential, and moderate risk assessment, the dam stands as a resilient structure that contributes to the overall environmental health and well-being of the region.

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.
