Updating the Washington Irrigation Guide (WIG)

Presentation by Melissa Downes, Washington State Department of Ecology; and Dan Haller, Aspect Consulting

The WIG is an important guidance document used extensively throughout the state for irrigation system design, irrigation scheduling and management, water rights evaluation, and hydrologic studies.  In 2008, the Department of Ecology (Ecology), Washington State University (WSU), and the United States Department of Agriculture’s Natural Resource Conservation Service (NRCS) funded an update to the Washington Irrigation Guide (WIG).  The current WIG was published in 1985 and estimates crop irrigation requirements for 90 locations throughout Washington State for 60 different crops.  With changes in climate, crops, irrigation systems, and ET methodologies, the existing WIG has become old and out-dated.  The new WIG will evaluate ET based on a new methodology for over 100 locations throughout the State, for nearly 100 different crops and using more recent climate data.  This presentation will explain:  Why the WIG update was needed; what tools Ecology uses to evaluate crop water use (and beneficial use), differences between the old WIG and new WIG and any policy issues that may result from implementation/adoption of the new WIG.
