Summary

Completed in 2006, this earth dam boasts a height of 25 feet and a hydraulic height of 20 feet, with a storage capacity of 125.31 acre-feet. With its primary purpose being flood risk reduction, the dam plays a crucial role in safeguarding the surrounding area from potential inundation during high water events.

Situated on Apple Creek, this controlled spillway dam spans 498 feet in length and covers a surface area of 5 acres. Despite its low hazard potential, the dam is rated as having a very high risk due to its critical function in flood control. While the dam's condition assessment is currently not rated, its risk management measures are yet to be fully detailed. With no outlet gates and a lack of associated structures, the focus remains on the dam's core function of protecting the local community from the impacts of flooding.

In the hands of a private owner, Clifford Hoehn Dam continues to serve as a vital infrastructure for flood risk reduction in the region. With the expertise of the USDA NRCS behind its design, the dam stands as a reliable bulwark against potential flood events, ensuring the safety and security of Old Appleton and its surrounding areas along Apple Creek.

Dam Data Reference

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.
