The Puget Sound watershed, the area west of the Cascades Mountains that stretches from the state capitol up to the Canadian border, is warming. It also faces rising seas, heavier downpours, larger and more frequent floods, more sediment in its rivers, less snow, and hotter, drier summer streams. A new report by the University of Washington synthesizes all the relevant research about the future of the Puget Sound region to paint a picture of what to expect in the coming decades, and how best to prepare for that future.
