Dog River Pipeline Replacement Project

New Pipe Ready for InstallationThe City of The Dalles is replacing 3.5 miles of aging wooden water supply pipeline in the Mt. Hood National Forest with new pipeline being designed to last 100 years or more. After serving The Dalles since the early 1900s, the current pipeline now leaks about 1 million gallons of water in the spring when Dog River runs high.

The Dog River Pipeline Replacement Project is the culmination of many years of City effort to improve reliability and resilience of the water system and will support the City’s goal of delivering the highest quality water to the community. 

Along with replacing the pipeline, the project also includes new fish screening and passage facilities, a new culvert near Brooks Meadow Creek, and interpretive signage for historic features.

Project Milestones

Construction of the new pipeline is expected to be completed by the end of 2023.

  • March 2022: Design Complete
  • June 2022: Site Preparation Complete
  • July-November 2022: Construction Season One Complete
  • May-November 2023: Construction Season Two Underway

Project Location

The pipeline is located in the Mt. Hood National Forest, and the City is working in close partnership with the Forest Service to coordinate trail user outreach and planned construction activities.
