Blog: Scenes from a Willamette River Summer

(August 30, 2019) - Each Friday during the summer, Environmental Services posts our Willamette River test results for bacteria and temperature at five popular recreation spots. Each week’s results this season were GOOD. And each week, you show what a river clean enough for swimming and playing means to you.

Here are scenes from a summer of play on the river - a river that is cleaner thanks in large part to your investment in the Big Pipe Project. 

PHoto - BES testing the water

What did our Willamette River test results show this season? All results were GOOD - showing bacteria levels well within state health guidelines. We sample at five locations each Wednesday and post results on Fridays.

Has the Willamette River always been clean enough to swim and play? No. Many longtime residents remember a polluted river but that’s changed. Thanks to the Clean Water Act, a variety of pollution prevention efforts and your investment in the Big Pipe Project, the river is cleaner than it’s been in decades. Your investment in the $1.4 billion Big Pipe project – the largest public works project in Portland history  – has eliminated almost all combined sewer overflows (CSOs) to the Willamette River and the resulting bacteria. Today, the river is almost always clean enough to swim and play.

How can you continue to protect the river we all love?

* Get there by bike - bicycling, walking, rolling and taking TriMet  help prevent air and water pollution. Plus, biking is fun and bike parking is free.

* Please prevent dogs and pets from pooping near the river and clean up after your pet waste. Dog poop is raw sewage. Whether from people, pets or wildlife, bacteria from sewage can make people sick. 

* Pack up all your trash (we don’t have to say that, right?) See our other clean river tips

Thank you Green Street Stewards - you've made 1600+ gallons of impact

The Green Street Steward program started with one person calling the City and expressing interest in helping keep green streets clean and functioning. Out of that one call, came a program that now involves almost 200 volunteers who help maintain Environmental Services' green street planters in their neighborhoods. Green streets filter and absorb stormwater, keeping pollutants out of creeks and rivers and adding green spaces and wildlife habitat to our neighborhoods.

We’ve asked volunteer stewards to report back, and the very impressive results are in for 2018:

514 hours volunteering

1297 gallons of trash collected

1631 gallons of debris (leaves, sticks, weeds, etc.) collected 

After tallying the accomplishments for 2018, the Green Street Steward Program awarded certificates and a prize to the following stewards for going above and beyond in the following categories. 

The Green Street Steward team is grateful for the work of community members to help maintain green streets, and we know there’s even more work happening that we don’t hear about! So volunteers: remember to tally your hours. And if you're not a volunteer yet, join us by visiting or emailing us at  

Our Business winners were:

Most trash collected Oregon’s Finest 75 gallons.

Oregons finest

Most debris collected Environmental Science Associates (ESA) 435 gallons.

 Award image

Most interesting find  PBS Environmental - they found a rug and utensils.


Most hours logged Henningson, Durham and Richardson, Inc (HDR) 38 hours.


Our individual winners were:

Most trash collected  William Scheuner with 58 gallons (no picture)

Most debris collected  Chris Prescott with 85 gallons

Chris Prescott

The most interesting find Jeff and Sarah Lyons  oyster shells

Most hours logged Lyle Remington 70 hours (no picture)

We also handed out an MVP (Most Valuable Partner) award to the Surfrider Foundation, Portland Chapter for organizing monthly and special holiday volunteer events to collect a total of 420 pounds of trash. (Photo credit: Chanel Hason)

For April 24: You’re Invited to the annual Southwest Watersheds Open House! Come learn about SW Watershed Improvement Projects

You’re Invited to the annual Southwest Watersheds Open House! Come learn about SW Watershed Improvement Projects.

When: Wednesday, April 24, 2019, 5:30 p.m. to 7:30 p.m.

Where: Multnomah Center, Room 33 - 7688 SW Capitol Highway

Stop by on your way home for refreshments, kids’ activities and information.

Environmental Services (BES) works with SWNI, the southwest community, and partner bureaus and organizations to develop watershed plans and projects to improve water quality, address public interests, enhance fish and wildlife habitat, improve infrastructure, and restore watershed functions.

Please join BES and SWNI at this open house to discuss recently completed and current projects and give feedback on projects in planning and early design phases. Your participation helps shape plans to fit the neighborhood.

Stop by on your way home for refreshments and information about plans and projects to improve the health of SW Portland’s watersheds. Kids’ activities will be available, and all are welcome. To request translation services, contact

A number of exciting projects in SW Portland will be highlighted, including:

Boones Ferry Road Culvert Replacement Project

Tryon Creek flows through a culvert under SW Boones Ferry Road that creates a barrier for fish moving to habitats in upper Tryon and Arnold creeks. Environmental Services is working with many partners to replace the culvert with a bridge. Construction expected in 2020.

SW Capitol Highway: Multnomah Village to West Portland    

Portland’s Bureau of Transportation, Bureau of Environmental Services, and Water Bureau are working in coordination on street, stormwater, water main, and fire suppression improvements on SW Capitol Highway. This project will improve safety and mobility for all modes of travel while improving stormwater management, protecting water quality in local streams, and updating water supply infrastructure to meet modern demands. Working together ensures successful outcomes—including reduced costs, improved efficiency, and enhanced service delivery to the Portland community. Construction is anticipated to begin in December 2019 and will last through most of 2020.

SW Texas Wetland Expansion Project

The existing Texas Wetland site will be expanded to capture and treat additional stormwater at the headwaters to Stephens Creek and help protect downstream water quality. A pedestrian connection through the area will also be provided. Construction expected in 2019.

Getting dirty for clean rivers: Prescott Elementary students add 400 native plants to Senn's Dairy Park

(March 14, 2019) - About 70 students from Prescott Elementary School got their hands dirty this month to contribute to clean rivers. They planted about 400 native plants at Senn's Dairy Park in the Parkrose neighborhood in partnership with Environmental Services and Portland Parks & Recreation.Parkrose students

The students learned about the benefits of native plants and habitat restoration and were able to apply their learning at a park in their own neighborhood.

As the students learned, native plants attract birds, butterflies, and beneficial species, provide habitat for wildlife, and help keep our rivers and streams healthy.

Native plants reduce pollution by acting as a sponge - absorbing rainwater and returning that water to the ground where it replenishes soil and groundwater, and in turn helping the plants grow. The alternative is turning rainwater into stormwater -  letting rainwater wash over streets where it mixes with motor oil, dirt, grime, pesticide residue and other pollutants that then end up down our storm drains and in our waterways. Native plants and other green infrastructure prevent pollution and add beauty and habitat to our neighborhoods.

Find out about Environmental Services' Clean Rivers Education program. 

Find out more about the benefits of native plants and what they look like at If you have an idea for a community planting, see Environmental Services' Native Plant Mini Grants.

People can also get involved in planting natives in local natural areas by connecting with local watershed councils and Portland Parks Stewardship.
