Relation Central Utah Project; Western Waters Digital Library; 2 developments scheduled for construction since 1976 estimates have been made of salinity impacts that could be expected with the five developments in the upper colorado river basin scheduled for construction since since 1976 table C 32 shows the develop ments effects on the colorado river system at points above imperial dam while table C 33 shows the estimated salinity impacts of the developments at imperial dam table C 33 also shows estimates of economic externali ternali externals ex ties of the salinity effects these externalities have been based on a rate of 230000 for each mg1 mgl mgt of salinity increase at imperial dam this rate has been estimated by the bureau of reclamation and takes into account reduced productivity and increased agricultural production costs that downstream water users might experience from the salinity impacts it also takes into account increased costs that might be necessary for treatment of municipal and industrial water as a result of salinity increases and the reduced life of water pipes and other facilities that would result from the increases in concentration table C 32 salinity effects of projects scheduled for construction in upper colorado river basin since 1976 as related to base conditions on colorado river system unit mg1 mgt 1 1 1976 effects base stream and modified of five with five reference point base projects projects green river ri er at green river utah 495 9 504 colorado river at lees ferry ariz 677 40 637 colorado river at imperi imperial imperl 31 dam 1102 50 21053 11053 91053 I 1 1 rounded to nearest unit 2 includes effect of las vegas wash ist ish ast 1st stage 3 overview of colorado river estimates of future salinity levels in the colorado river are highly speculative various entities have made projections in the past and have arrived at differing estimates because of different base condi eions tions assumed with respect to quantity of runoff rate of development and implementation of salinity control measures in order to provide some early perspective of projected salinity levels in the river however this section includes a discussion of bureau of reclamation estimates and the results of one of several analyses made by the colorado river basin salinity control forum in it its s study the bureau of reclamation analyzed effects of 43 water resource developments and 17 salinity control measures except for the froitland fruitland Fruit land mesa and savery pot hook projects which were excluded from the study since they were not funded in the 1977 public works appropriat appropriate ion bill the developments are the same as those discussed in the final C 90
