Relation Central Utah Project; Western Waters Digital Library; of about 1.9 19 lg ig million tons of salt annually this level represents a concentration reduction of about 204 mgl mg1 mgt at imperial dam in the year 2000 which only partially offsets the expected maximum total concen tration aration of 120 1205 5 mg1 mgl mgt in order to attain the adopted salinity standard additional control augmentation or management steps will be necessary thus weather modification vegetation man management agement argement watershed improvement additional salting desalting de and various nonstructural measures remain to be considered and studied in detail curve A on figure C 4 shows the shape and magnitude of salinity salinityeffects effects of anticipated colorado river basin development from the 43 identic identif identified led water water resource development projects without any salinity control curve B shows salinity effects e shown by curve A accompanied by the timely construction of df four authorized salinity control units curve C shows the cumulative effects of incorporating the 17 salinity control units authorized an and dunder under study curve D shows the additional measures needed to obtain the 1976 salinity standard the colorado river basin salinity control forum analyzed an array of runo runoff ff and depletion levels in developing the salini salinity ty standards the res resuit result uit of one of its analyses are plotted in figure C 5 curve A represents the S salinity effects of the anticipated basin development without salinity control measures curve B represents the effect of adding the 4 authorized salinity control projects 12 of the salinity control projects under investigation meeker dome not included and the adoption of a no salt return policy to industrial development the forum has concluded that the salinity standard can be maintained through 1990 under certain sets of conditions recognizing the inherent diffi difel defel culty in projecting cumulative future impacts in the basin a key pro vision allows for reassessment and review of salinity criteria every 3 years the methods of analysis used by the forum and the bureau of reclamation are similar the input assumptions were different however and the resulting projected 1990 salinity levels are different the following is a comparison of one set of assumptions used by the forum with those used by the bureau in its study bureau of reclamation forum virgin runoff 13900000 acre feet 15000000 acre feet lees ferry depletion level 13500000 acre feet 12600000 acre feet C 88
