I-5 - Woodland Vicinity at Horseshoe Lake - Upgrade Pump System

Project news

  • Project Awarded on April 13, 2020 to Rotschy, Inc.

Needs & benefits

The Horseshoe Lake pump station located along Interstate 5 near the City of Woodland in Cowlitz County is a water intake and pump system that moves water from the Lewis River into Horseshoe Lake. The pump keeps water flowing between the lake and the Lewis River and helps maintain water quality in the lake. The existing pump system is deteriorating and has outlived its service life.

In summer 2021, contractor crews will install a new pump system, which includes a dock, pump house, and associated electrical improvements. Additionally, the existing fish screens that help keep fish safe from being pumped through the system do not meet current Department of Fish & Wildlife regulations and must be replaced.

What will be the result of this work?

The new pump system will provide a more reliable flow of water into Horseshoe Lake, helping to maintain good water quality and reduce the need for costly repairs for years to come. The new system will also bring fish screens up to current standards.
