Summary
The dam is an earth type structure with a height of 25 feet and a length of 552 feet, providing a maximum storage capacity of 88 acre-feet. The dam is situated on Troublesome Creek within the Rock Island District, and is owned and operated by the local government.
Despite being classified as having a low hazard potential, the dam has a moderate risk assessment rating of 3. It has not been inspected since September 1998, with a scheduled inspection frequency of once per year. Troublesome Creek Watershed Dam T-43 does not have an emergency action plan in place, and its condition assessment is currently listed as "Not Rated." While the dam is not regulated by the state and has no enforcement or permitting requirements, its risk management measures and overall risk assessment remain unspecified.
As a crucial infrastructure for flood risk reduction in the area, Troublesome Creek Watershed Dam T-43 serves an important role in protecting the surrounding community from potential water-related disasters. However, the lack of recent inspections and emergency preparedness highlights the need for continued monitoring and maintenance to ensure the safety and functionality of the dam for both residents and the environment.

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.
