Summary

Built in 1917, this earth-type dam stands at a height of 79 feet and serves multiple purposes including flood risk reduction, hydroelectric power generation, and recreation. With a storage capacity of 56,000 acre-feet and a surface area of 6,212 acres, this dam plays a crucial role in managing the Chippewa River's flow and providing essential water resources to the region.

Despite its age, Wissota South Saddle Dike continues to operate effectively, with a hazard potential classified as high due to its critical function in water management. Regular inspections by the Federal Energy Regulatory Commission ensure its structural integrity and safety standards are upheld, although specific condition assessments are not publicly available. With no recent modifications or risk management measures reported, the dam remains a key component of the local water infrastructure, contributing to both environmental protection and community well-being.

As a significant piece of Wisconsin's water resource system, Wissota South Saddle Dike stands as a testament to the enduring importance of hydroelectric power and flood control in the region. With its historical significance, ongoing regulatory oversight, and essential role in water management, this dam is a focal point for water resource and climate enthusiasts seeking to understand the intersection of infrastructure, environmental stewardship, and public safety in the face of changing climate conditions.

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.
