Summary
Completed in 2000, this earth dam stands at 29 feet high and spans 1010 feet long, with a storage capacity of 24 acre-feet. Situated on the TR- Hanlins Creek, this dam plays a crucial role in managing stormwater runoff and protecting the surrounding community from potential flooding events.
Managed and regulated by the Iowa Department of Natural Resources (Iowa DNR), the Thf Stormwater Detention Dam is designed to handle moderate risk levels with a low hazard potential. Its uncontrolled spillway type and stone core foundation contribute to its functionality in controlling water flow and reducing the impact of heavy rainfall on the local environment. While the dam's condition is currently not rated, its strategic location and design make it a significant asset in the region's water resource management and climate resilience efforts.
As a key infrastructure for flood risk reduction, the Thf Stormwater Detention Dam serves as a critical component in the overall water management system of Scott County, Iowa. With its primary purpose focused on flood control, this dam showcases the importance of sustainable water infrastructure in mitigating the impacts of extreme weather events and climate change. Its presence highlights the collaborative efforts between private owners, designers, and state regulatory agencies to safeguard communities and enhance the resilience of water resources in the face of a changing climate.

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.
