<br />.0 <br /> <br />miles of pipelines and 49 sprinkler systems on 950 acres have been installed. The salt load <br />reduction accomplished to date is 2,300 tons/yr. <br /> <br /> <br />I-' <br /> <br />Moaoa Vall~ ruSDA!: This unit is located in southeastern Nevada and includes 19,500 <br />acres of irrigated land in the Meadow and Moapa Valleys along the Muddy River, immediately <br />upstream from Lake Mead. This unit includes installation of a 46-mile underground piped <br />delivery system and onfarm salinity control practices. By reducing seepage and excess deep <br />percolation, the annual salt load is expected to be reduced by 18,700 tons. The final Plan/EIS <br />was issued in January 1993, and a Record of Decision was published in the Federal Reiister on <br />February 26, 1993. In 1989, the Nevada State Legislature appropriated $500,000 for <br />implementation, contingent upon matching funds from Clark County and the Muddy Valley <br />Irrigation Company. <br /> <br />San Juan River-Hammond {Reclamation and USDA!: San Juan River Unit drainage <br />contributes approximately one million tons of salt annually to the Colorado River Basin. In the <br />Hammond area, Reclamation has completed a draft planning reportlEIS. The recommended plan <br />proposes to line all unlined sections of the Hammond Project Irrigation system. The estimated <br />salt load reduction would be 28,000 tons/yr. SCS completed an investigation in 1992 to explore <br />the potential for a USDA program in the San Juan River Basin in the Hammond area. <br />Investigations indicated that a USDA onfarm program is not cost-effective in this area. <br /> <br />Price-San Rq,fael Rivers {Reclamation and USDA!: An estimated 430,000 tons of salt <br />annually reaches the Colorado River from these two river basins. The Price and San Rafael <br />rivers, tributaries of the Green River, Utah are 120 miles southeast of Salt Lake City. <br /> <br />SCS and Reclamation prepared a draft joint plan and EIS for the Price-San Rafael Rivers <br />Unit. Reclamation will install salinity control features in the irrigation distribution system and <br />USDA will assist individuals and groups with applying onfarm salinity reduction practices. <br /> <br />The draft planning reportlEIS has been completed, and the final planning reportlEIS is <br />scheduled for completion in 1993. Under the preferred plan, salt loading to the Colorado River <br />System would be reduced by an estimated 161,000 tons/yr. <br /> <br />Units Under Consideration But Not Currently in the Plan <br /> <br />San Juan - HOiback {Reclamation and USDA!: In 1992 investigations were initiated in <br />the San Juan River Basin west of the Hogback to determine if a salinity control project is cost <br />effective in this area. The study area lies within the boundaries of the Navajo Indian Nation. <br /> <br />Lower Viriin River {Reclamation!: In April 1992, Reclamation began a cooperative study <br />with the Las Vegas Valley Water District of a water supply and salinity control project on the <br />Lower Virgin River in Nevada. The water would be desalted for use in Las Vegas Valley. The <br />plan is to divert water from the Virgin River, desalt the diverted water, and pipe it to the Las <br />Vegas Valley. A Preliminary Findings Report was completed in April 1993. <br /> <br />4-8 <br />
