Summary

Built in 1968 by the USDA NRCS, this earth dam stands at 25 feet tall and spans 720 feet in length. With a primary purpose of recreation, Meinhardt serves to reduce flood risks while providing a recreational space for locals and visitors alike. The dam has a storage capacity of 50 acre-feet, with a normal storage level of 20 acre-feet.

The Meinhardt dam has a high hazard potential due to its location and structural characteristics, but it has been assessed as being in satisfactory condition as of November 2020. The dam is state regulated, with inspections conducted regularly by the Wisconsin Department of Natural Resources. Despite its moderate risk rating, Meinhardt remains an important structure for water resource management in the area, with a maximum discharge capacity of 159 cubic feet per second. With its uncontrolled spillway and a history of maintaining safety standards, Meinhardt continues to play a crucial role in the local ecosystem and community.

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.
