The Estuary Partnership is undertaking the first, large-scale effort to identify and map marine debris in the lower Columbia River from Bonneville Dam to the Pacific Ocean. We're tracking small to medium size marine debris (less than 35-feet) - things like tires, styrofoam blocks, small boats, machinery, and other material that may harm the river. We'll use this information to understand how big the problem is, and make a plan for how to clean it up.
