Abstract
The Columbia River Basin (CRB) encompasses parts of seven US states and
British Columbia in Canada over a land mass approximately the size of France. It is
a vital part of the ecosystem and economies of the entire region. The CRB, like
many watersheds around the world, is experiencing increased pressure on water
resources and ecosystems, due to population growth, threatened and endangered
species, economic development, and climate change. Irrigation is responsible for
the majority of consumptive use in the watershed so the implications of climate
change are a tremendous concern as we strive to feed a growing population. To
facilitate strategic planning and investment, the State of Washington requires a
long-term water supply and demand forecast (the Forecast) every five years. An
interdisciplinary WSU research team integrated three biophysical models with an
agricultural economics model to conduct a system-wide assessment of how
future environmental and economic conditions are likely to change water supply
and demand by 2030. Timing of supply changes will shift water away from the
