Summary
This earth dam stands at a height of 24.1 feet and has a hydraulic height of 24 feet, with a total structural height of 34 feet. It has a storage capacity of 65.32 acre-feet and serves a drainage area of 146 acres, offering vital protection to the surrounding community.
With a low hazard potential and a moderate risk assessment rating, Troublesome Creek Watershed Dam S-50 plays a crucial role in mitigating flood risks in the area. Although not currently state regulated or inspected, this dam serves as a vital asset for fire protection, small fish ponds, and wildlife habitats in addition to flood control. The dam's uncontrolled spillway and outlet gates further highlight its importance in managing water resources in the region.
As a key structure in the Rock Island District, Troublesome Creek Watershed Dam S-50 exemplifies the collaboration between local government and federal agencies in safeguarding the environment and communities from the impacts of extreme weather events. Its strategic location and design reflect a commitment to sustainable water resource management and climate resilience in the face of changing environmental conditions.

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.
