Construction project and drawdown planned for mid-April through end of year.

In 2018, WPS completed a project assessment and engineering detail to replace three original Tainter gates on the Wausau hydroelectric plant. The gate replacement is needed to reduce leakage, improve plant efficiency and reduce operation and maintenance costs.

Construction upgrades are currently underway, reservoir will return to normal operating levels by Dec. 31, 2019.

Construction includes:

  • Replacing three original spillway gates.
  • Repairing concrete piers and abutments.
  • Installing a new gate heater for winter operation.
  • Upgrading the spillway electrical system.

As part of this project, there will be up to a 14-foot drawdown of the reservoir north of the hydro plant mid-April through December to allow for work on the foundation of the gates.

WPS will work with the Wausau police and fire departments, and Marathon County Emergency Management to manage the area for contractor and public safety.

Some recreational areas will be impacted during the project construction. This includes fishing on the immediate east and west sides of the hydroelectric facilities. The canoe and kayak portage route also has been temporarily moved to avoid the construction area.
