Measuring and reporting on our rivers and streams


Sure, the Willamette River is Portland’s front yard, centerpiece and working harbor.  But did you know, Portland has about 300 total miles of rivers and streams in the city?

Have you ever wondered about water quality in the river, conditions along Johnson Creek, or the health of fish populations in Tryon Creek?

coho salmonCheck out the new Watershed Report Cards!

This is a new tool we have to report on the current conditions of our streams, the Willamette River, and our watersheds. 

Watershed report cards are used by many communities, like the Chesapeake Bay region, Puget Sound, and Toronto, Canada, to help people understand what’s going on in the environment.

Environmental Services is working for clean rivers and healthy watersheds.  Many other city bureaus, community partners, and regional organizations are part of the effort, too.  Even your individual actions, like planting a tree or reducing pesticides in your yard, make a difference.

The report cards will help us track changes in local water quality, habitat and salmon populations over time.  They will also help show where everyone’s efforts can make a difference.
