Summary
This earth dam stands 26 feet tall and stretches 680 feet in length, with a storage capacity of 96 acre-feet. Situated on Troublesome Creek, this dam plays a crucial role in managing water flow and protecting the surrounding area from potential flooding events.
Despite being classified as having a low hazard potential, this dam has a moderate risk assessment rating of 3. It has not been inspected since September 1998, with its condition currently listed as "Not Rated." While it boasts a spillway width of 20 feet and a maximum discharge rate of 78.4 cubic feet per second, there are no outlet gates associated with this structure. Additionally, it has not had an Emergency Action Plan (EAP) prepared, raising concerns about emergency preparedness and response in the event of a dam failure or other critical situations.
As an enthusiast interested in water resources and climate issues, Troublesome Creek Watershed Dam T-127 presents an intriguing case study for examining the management and maintenance of infrastructure designed for flood risk reduction. With its location in the Rock Island District and oversight by the Natural Resources Conservation Service, there is a unique opportunity to explore the intersection of environmental protection, water resource management, and infrastructure resilience in the face of changing climate 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.
