Salinity Control Opportunities tv c.n If salinity control joined this consortium and contributed $30 per ton toward the project, the rest of the group could probably fund the remaining $6 to $7 million required for a fix, The salinity control portion would be approximately $3.4 million, The total fix would benefit numerous water users and the razorback sucker both locally and throughout the Colorado River Basin, ,-.... o 8ig Sandy River Unit The Big Sandy River study area is located near Farson and Eden in Sweetwater County in southwestern Wyoming, The study was specifically directed toward reducing salt pickup from seeps and springs along a 26-mile reach of the Big Sandy River west of Eden, Wyoming, Investigations indicated that seeps, which surface in the Bone Draw and Big Bend areas, produce saline water at a rate of about 27 cfs, The salinity varies from 1,000 to 6,000 milligrams per liter (mg/L) along the Big Sandy River, with a total annual contribution of more than 164,000 tons of salt, Indications are that salt is picked up by water contacting the shale of the Green River Formation beneath the surface and eventually seeping into the river, Irrigation was identified as a significant source contributor to the water recharging the springs, Reclamation evaluated ways to intercept and use the saline springs for industrial processes, In the irrigated area, Reclamation studied off-farm solutions, such as selective lining of canals and laterals; however, previous selective lining programs were shown to have been effective; only low seepage rates were found, Studies conducted in cooperation with the U,S, Department of Agriculture (USDA) indicated that control of onfarm irrigation is the most cost-effective alternative for controlling salinity from the Big Sandy Unit, USDA is implementing their plan, Blue Springs The Blue Springs 'study area was located on the Little Colorado River within the Navajo Hopi Indian Reservation in north-central Arizona, The springs contribute an average of 160,000 acre-feet per year with an average salinity of 2,500 mg/L and a total salt load of about 550,000 tons per year, The lower portion of the Little Colorado River flows through a meandering canyon that is about a mile wide and a half mile deep, The walls of this rugged gorge are a series of nearly vertical cliffs of massive limestone and sandstone separated by steep slopes or benches of shale, siltstone, or thin bedded sandstone, The bottom can be reached near Blue Springs only by a rugged foot trail from the rim or by helicopter, The springs originate from ground water which moves into the area from the east and south and B-2
