This presentation covers how evapotranspiration (ET) can be used to inform irrigation decision and provides examples of three, free university supported ET-​based irrigation scheduling tools being used by Ogallala region/​High Plains producers: WISE from Colorado State University, KanSched from Kansas State University, and the DIEM irrigation scheduling tool from TX.
