Staff from the Lower Columbia Estuary Partnership spent three days in early September cleaning up medium-sized debris from the shoreline of Sauvie Island and Multnomah Channel.
A lovely morning and empty dumpsters await the clean up.
We selected this stretch of river because our previous surveys found a high concentration of debris, so we knew we could have an impact there.
Chris pries a tire from the mud.
Our clean up was boat and barge-based, in order to reach areas of the river inaccessible by car or foot. We focused on picking up materials that are too large for volunteers or good Samaritans, like tires, tarps, and large chunks of Styrofoam.
Our most common find was car and truck tires. There is a distressing number of tires on the shoreline, and we know that there are more under the water. Over these three days, we pried more than 200 tires up from the mud!
Non-tire junk was also gathered.
Tarps (and everything else) get really heavy with mud!
Large blocks of Styrofoam was a common find.
So much polystyrene!
Styrofoam was taken to Agilyx in Tigard, who were eager to work on techniques to dry it sufficiently for it to be recycled.
