Salinity Control Opportunities '" UI .... .... emerges asspringflow where the canyon has penetrated the Redwall and Mauve Umestones below the regional water table, There are many spring openings along two relatively well-defined reaches. A full scale feasibility study of It he project is not planned due to the high capital cost of building the projE!ct and the historical and religious value of the area to the Hopi Indians, Dirty Devil River Unit The Dirty Devil River study area was located in Emery and Wayne Counties in southern Utah. The study area included the Muddy Creek, the Fremont and Dirty Devil Rivers, and the tributaries of Muddy Creek, Hanksville Salt Wash, aIld Emery South Salt Wash. The Dirty Devil River drainage contribu$s approximately 150,000 tons of salt each year to the Colorado River. TlJ.e Muddy Creek tributary contributes an average of 86,000 tons of salt annually. No significant sources of salt or potential alternatives were identifieq on the Fremont River or its tributaries, Approximately 28 percent of the Mdddy Creek salt load (24,200 tons per year) comes from springs in HanksvilJe Salt Wash and Emery South Salt Wash, Reclamation evaluated reducing the salinity of the Dirty Devil and Colorado Rivers by collecting saline spring water in Hanksville Salt Wash and Emery South Salt Wash and disposing of it by deep well injection. This means of disposal would reduce the salt contribution to the Colorado River by 20,900 tons annually. The unit was thought not to be cost effective, Glenwood-Dotsero Springs Unit Glenwood..Dotsero Springs is located along the Colorado River in Eagle, Garfield, ~nd Mesa Counties in west-central Colorado, The springs are located nElar the town of Glenwood Springs and the rural community of Dotsero. The combined annual discharge of the springs is 25,000 acre-feet of water Which contain about 440,000 tons of salt, About half of the salt contribution comes from 20 surface springs; the remainder enters as seeps and undetiwater springs within the river channel. Reclamatii>n started its planning investigations in 1980, The most cost- effective plan at the time consisted of collecting both surface and subsurface salt water:at Dotsero and transporting the salt water in a gravity flow pres- sure line tP Glenwood Springs where additional surface and subsurface salt water would be collected and added to the Dotsero salt water, The water would then be piped to evaporation ponds at the Colorado-Utah border, At $126 per ton, this plan could not compete with alternatives available in other unit~. Plans were deferred until a more cost-effective alternative, possibly aIj. industrial use, could be found. A planning report concluding the evaporatiop. pond alternative was completed in February 1986, B-3 ",,' '., .,' , ,..;, . 4 , q A '1
