Abstract: Approximately 37 percent of the salt contribution in the Colorado River can be attributed to irrigation activities in the river basin. The United States Department of Agriculture (USDA), in cooperation with farmers, has initiated an extensive salinity control program to reduce salt loading to the Colorado River. Early efforts were directed to a successful onfarm irrigation water management program in the Wellton-Mohawk area. Also, the Soil Conservation Service (SCS) completed salinity control studies and prepared reports for various irrigated areas. The USDA salinity control program is being implemented in four areas, other areas are awaiting implementation funds and planning is underway in two additional areas. A variety of salinity control practices are being applied by farmers with assistance from USDA.
