Sanitary Sewer Overflow Due to Vandalism, Warning Signs Still Posted

Due to vandalism, sewage has overflowed directly into Mill Creek and into the Columbia River. The sewer pipe has been cleared and the pipe has been repaired. No more sewage is overflowing.

Out of an abundance of caution, signs have been placed at locations of public river access on the Oregon shore of the Columbia River, from The Dalles Riverfront Park to West Mayer Park boat launch. The signs say: “Warning - Contaminated Water - No water contact” and give phone numbers to call for information.  These signs will remain in place at least until Thursday September 29, 2022 to allow time for water quality testing. Read the full press release here.

Dog River Pipeline Replacement Design Complete, Getting Ready for Construction

Dog River Pipeline Head GateThe City recently achieved a big milestone and completed design for the Dog River Pipeline Replacement project. The Dog River is an essential source of drinking water that provides more than half of the City’s annual water supply. With the new pipeline, the City is taking strides to improve reliability and resilience of the water system by replacing a 3.5-mile aging wooden pipeline in Mt. Hood National Forest.

Now that pipeline design is wrapped up, the City is working with key project partners at the Forest Service and gearing up for two seasons of construction. In the next few months, the pipeline corridor will be cleared of trees and brush to prepare for summer construction activities. The work is planned over two seasons to allow for mountain weather.

To keep customers and recreation users up to date on the latest, the City created a project webpage with background materials and upcoming milestones. For more project information and to sign up to receive project announcements visit
