Irrigation uses 80 percent of the water in the Pacific Northwest, and center pivots irrigate over half of watered acreage. For the past three years, R. Troy Peters, associate professor and Extension irrigation specialist at BSYSE WSU Prosser, have been the primary investigator of Low Elevation Spray Application (LESA) technology for center-pivot irrigation.

The project is funded by Bonneville Power Administration, with University of Idaho as a subcontractor. It was featured in a front-page article in the Capital Press.
