Come Play in the River at the Big Float


It’s hard to believe, but it’s already time for the fourth annual Big Float!  On July 27, join Portland’s celebration of the Willamette River with the Human Access Project and other sponsors.

People of all ages are welcome to grab an inner tube for a leisurely float, with live music on the water, a parade and after party.  What a great way to cool off on a hot summer day.

Yep, the Willamette’s water quality is safe for swimming in the summer and much of the rest of the year!

This is thanks to Portlanders’ investment in the "Big Pipes" and other projects to reduce combined sewer overflows to the river. 

Environmental Services continues to protect this investment and further improve conditions in our rivers and streams with green infrastructure to manage stormwater, environmental restoration projects, sewer system improvements and pollution prevention efforts.
