Summary
This dam, standing at 38 feet tall and stretching 580 feet in length, serves the critical function of flood risk reduction in the area. With a storage capacity of 108 acre-feet and a drainage area of 0.23 square miles, this structure plays a vital role in managing water resources in the region.
Managed by the local government and regulated by the Iowa DNR, Troublesome Cr Watershed Site 36-5 is classified as having low hazard potential with a moderate risk assessment rating. Despite not being currently rated for condition assessment, this dam is inspected, permitted, and enforced by the state regulatory agency to ensure its structural integrity and functionality. With its uncontrolled spillway and soil foundation, this dam remains a key component in water management efforts in the region, underscoring its importance in safeguarding the community from potential water-related disasters.
As a part of the Rock Island District and situated along Troublesome Creek, Troublesome Cr Watershed Site 36-5 is a vital piece of infrastructure in the water resource and climate management landscape of Iowa. With its primary purpose of fire protection and flood risk reduction, this dam stands as a testament to the collaborative efforts between federal and state agencies in maintaining the safety and sustainability of water resources in the area. Despite its moderate risk assessment, this structure continues to play a crucial role in protecting the community and its surroundings from the impacts of water-related hazards.

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.
