America's Most Endangered Rivers. 2016.

American Rivers, an organization involved in protecting, restoring, and conserving water systems through the U.S. has added Washington's Green-Duwamish River to its 2016 list of the country's ten most endangered rivers. To make the list, the river must play a significant role for the surrounding human and natural community, be impacted by climate-induced factors, and have a proposed action plan in the coming year that could greatly improve the health of the river. For the Green-Duwamish River, this action plan concerns the Army Corps of Engineer's construction of a salmon passage that would mitigate river obstruction caused by dams. Called the Howard Hanson juvenile fish passage system, the Army Corps and NOAA are proposing a new project that would begin in 2021. In addition, a management and funding plan for the river has been proposed that would integrate local, state, and federal efforts to clean up the river. The actions taken in the next year will have major consequences for the future health of the river.
