Overview: Thanks to ratepayers’ investment in the $1.4 billion Big Pipe project – the largest public works project in Portland history that was completed in 2011 - almost all combined sewer overflows (CSOs) to the Willamette River have been eliminated. With that drop in sewage exposure comes a drop in E. coli bacteria – an indicator of fecal matter and the single biggest health concern for swimming and other direct contact recreation, according to the state Department of Environmental Quality.
Other E. coli sources include poop from wildlife and pets (thank you for picking up after your dog). Because of the public’s interest in recreation on the Willamette River, Environmental Services tests for bacteria weekly during the summer – it’s one way you can be assured of bacteria levels and see and experience the results of your investment in the Big Pipe project. Find out test results by clicking on the map or the list of sites below.
Note: Environmental Services collects weekly samples from late May through September to measure for E. coli bacteria and temperature at five popular public access points. Water samples are collected on Wednesdays and results posted by Friday morning – just in time for the weekend.
Year-round monthly testing:
Note: Environmental Services collects water samples monthly at three locations on the Willamette River to track long-term water quality trends.
Keep in mind many factors affect your safety on the river, including temperature, currents and debris in the river as well as your skills and ability in the water. Remember, cold water is healthy for fish, but it can be uncomfortable and even unsafe for people. Know the water, know your abilities, and stay safe while enjoying the river.
Poet's Beach, the City of Portland’s Willamette River swimming beach, will be open this summer from Thursday, July 12, through Sunday, August 26, 2018. First established as a pilot project in 2017, the beach will open daily (5am- midnight) for recreational swimming during the summer of 2018. Poet’s Beach is a sandy shore with river access, and an in-water swimming area delineated with a swim line and floats. It is managed by Portland Parks & Recreation.
Be advised, combined sewer overflows (CSOs) are rare but may still occur during periods of heavy rain. When these overflows of stormwater mixed with sewage occur, CSO Advisories are posted here and on the home page. During CSOs, the public is advised to avoid contact with the river for 48 hours due to increased bacteria.

Reducing sewage overflows is one way Environmental Services is working for a healthier river. Environmental Services also is restoring habitat, preventing pollution through a variety of programs, and collaborating with other parties to clean up the Portland Harbor Superfund site.
