They are supposed to protect us’: Community wants more from EPA for Duwamish Superfund cleanup

The Duwamish River once meandered through a tidal wonderland of wetlands, sloughs, side channels and oxbows — some 5,300 acres of habitat for wildlife, including salmon, birds and a banquet of insect and invertebrate life.

That all started changing with the arrival of settler-colonizers questing for flat land for development. Beginning in the early 1900s, the Duwamish was steadily straightened, dredged and filled.
