<br />. <br /> <br />. <br /> <br />. <br /> <br />M . - - I. f) <br />L~(V'iCl <br /> <br />Implementation of Reclamation and Agriculture salinity control <br />activities is continuing on the Grand Valley, uinta Basin, Paradox <br />Valley, Dolores/McElmo Creek, Lower Gunnison Basin, and Big Sandy <br />River Unit. However, it will be a number of years before <br />significant effects are felt at the three lower mainstem stations. <br /> <br />Although current salinity levels in the Colorado River System <br />are below the criteria level, studies by the Forum and Reclamation <br />show that salinity concentrations will continue to increase over <br />the long term. If planned salinity control measures as set forth <br />in the 1990 Review are implemented, the man-caused increases in <br />salinity can be held within the prescribed numeric criteria through <br />the year 2010, based on the average water supply conditions. While <br />the levels of salinity concentrations will increase slowly, efforts <br />to control salinity take many years to accomplish. Once completed, <br />a salinity control project will take a number of years (4-5) for <br />the full impact of the control measures to show results at Imperial <br />Dam. Planning and implementation of the salinity control program <br />also requires considerable time because of the many uncertainties <br />associated with the complex and unique technologies required for <br />salinity control. Therefore, it is imperative that the salinity <br />control program as set forth in 1990 Review be carried out as <br />scheduled. <br /> <br />17 <br />
