Summary

6, is a local government-owned flood risk reduction structure located in Crawford, Wisconsin. Built in 1974 by the USDA NRCS, this earth dam stands at a height of 45 feet and stretches 500 feet in length along the TR-NEDERLO Creek. With a storage capacity of 365 acre-feet and a maximum discharge rate of 1190 cubic feet per second, it plays a crucial role in managing water flow and debris control in the area.

Regulated by the Wisconsin Department of Natural Resources, the Blackhawk-Kickapoo Project is considered to have a significant hazard potential with a very high risk assessment rating. However, its condition assessment as of September 2017 was reported as satisfactory. The structure is inspected every three years to ensure its safety and effectiveness in mitigating flood risks for the surrounding community. With its controlled spillway and state-of-the-art design, the Blackhawk-Kickapoo Project remains a vital asset in protecting the area from potential water-related disasters.

This project, supervised by the St. Paul District of the US Army Corps of Engineers, exemplifies the collaboration between local, state, and federal agencies in managing water resources and climate-related risks. As climate change continues to impact the frequency and intensity of extreme weather events, structures like the Blackhawk-Kickapoo Project are essential for safeguarding communities and natural habitats against the threats of flooding and debris flow. Its strategic location and design demonstrate the commitment to sustainable water resource management and environmental resilience in the face of a changing climate.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
