Efforts underway to improve irrigation efficiency in the basin using federal funds have included conversions to sprinkler irrigation systems and to higher efficiency graded border surface irrigation systems. With dramatic increases in power rates for agricultural users on the horizon, surface irrigation enhancements have significant promise to increase water use efficiency without substantially increasing production costs. While these projects generally do not solve the basin's water supply problems, they do provide a significant enhancement to surface water quality by reducing sediment and nutrient containing surface return flows. In areas where groundwater levels are declining due to irrigation pumping, these projects can also reduce stresses on groundwater supplies. A project implemented near Sprague River is used as a case study to describe how the simple conversion from ditched to piped laterals, creation of new border ridges, and improvements to irrigation scheduling can dramatically increase irrigation application efficiency while at the same time reducing pumping costs and groundwater withdrawals without any increase to daily labor requirements.born digitalproceedings (reports)engCopyright and other restrictions may apply.
