The Portland Harbor segment of the Willamette River is a troubled waterway by almost any measure. Decades of industrial use have resulted in the harbor's imminent listing as a Superfund toxic cleanup site. Portland's storm sewer system dumps a mixture of raw sewage and and stormwater into the Willamette River whenever it rains, a violation of state water quality standards. And recent Endangered Species Act listings oblige the city to take costly steps to facilitate the return of native salmon. Interaction with water is exactly the focus of the living water parks proposed by Keepers of the Waters.
