Summary

Built in 1969 by the USDA NRCS, this dam serves primarily for flood risk reduction purposes, with added benefits for recreation. With a height of 63 feet and a capacity of 2345 acre-feet, it plays a crucial role in managing water resources in the area, covering a surface area of 51 acres and draining an 8-square mile watershed.

Despite its importance, West Fork Kickapoo 1 has been deemed to have a high hazard potential and an unsatisfactory condition assessment as of September 2018. Regular inspections are conducted every two years, with the last one taking place in October 2017. The dam poses a moderate risk (Level 3) and falls under the jurisdiction of the Wisconsin Department of Natural Resources, with state regulations, permitting, inspections, and enforcement in place to ensure its safety and functionality. It is crucial for water resource and climate enthusiasts to monitor and support the maintenance and management of such vital infrastructure to mitigate potential risks and protect the surrounding community and environment.

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.
