Summary
This earth dam stands at a height of 32 feet and has a structural height of 41 feet, with a capacity to store 135 acre-feet of water. The dam spans 600 feet in length and covers a surface area of 16 acres, serving a drainage area of 250 square miles in the Marion County region.
The dam is classified as low hazard potential and has not been rated for its condition assessment. Despite its low risk, the dam has a moderate risk assessment score of 3. The spillway, which is uncontrolled, has a width of 35 feet. Troublesome Creek Watershed Dam S-94 has no associated locks or outlet gates, and it has not been modified since its completion. While the dam has not been inspected since February 1998, its emergency action plan status and risk management measures are currently unknown.
For water resource and climate enthusiasts, Troublesome Creek Watershed Dam S-94 offers a fascinating case study in flood risk reduction infrastructure. With its strategic location along Troublesome Creek and its capacity to manage water flow in the region, this earth dam plays a crucial role in protecting the surrounding area from potential flooding events. As efforts continue to monitor and assess the condition of this dam, it remains an important asset in safeguarding the local community against hydrological risks.

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.
