Washington Water Outlook

March 21, 2005


The 2005 snowpack is unfolding as one of the worst in the past 50 years in the Washington Cascades and Olympics, with potentially serious consequences for a variety of needs.


A special workshop sponsored by the University of Washington Climate Impacts Group will outline how we got to where we are, and what is likely to happen next. Recent developments in streamflow forecasting by scientists at UW, the National Resources Conservation Service, and the National Weather Service provides state-of-the-science ensemble (probabilistic) predictions of streamflow for lead times of six months and longer. In addition to evaluating how bad the year's flows will be, the workshop will include a description of the climatic conditions that led to this situation and the likelihood of a reprise. Agency experts will discuss the implications of the evolving drought for the region's water resources and salmon. Open discussions will follow each talk.

Who should attend

Water resource managers, hydropower interests, fisheries biologists, environmental and science reporters, and others interested in the state's water outlook.
