Summary

The dam, completed in 1962, serves multiple purposes including fire protection and providing a small fish pond. With a height of 13 feet and a length of 1000 feet, Reischl has a storage capacity of 80 acre-feet and a drainage area of 0.3 square miles. The dam is regulated by the Wisconsin Department of Natural Resources (WIDNR) and is inspected regularly to ensure its structural integrity and safety.

Despite being classified as having a low hazard potential, Reischl is considered to have a moderate risk level (3) according to a risk assessment. The dam has a satisfactory condition assessment as of April 2013, with emergency action plans in place. The surrounding area is at low risk of inundation, and the dam is equipped with an uncontrolled spillway. Reischl plays a vital role in the local ecosystem, providing water for fire protection and supporting aquatic life in the small fish pond.

For water resource and climate enthusiasts, Reischl offers an interesting case study in dam management and regulation in Wisconsin. The dam's history, design, and purpose highlight the importance of balancing human needs with environmental considerations. By staying informed about the condition and risk level of dams like Reischl, enthusiasts can contribute to the sustainable management of water resources and the protection of ecosystems in the face of climate change.

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.
