| Relation | Central Utah Project; Western Waters Digital Library; has estimated no additional salt pickup from the jensen unit lands receiving a supplemental water supply these lands nave have been irrigated for many years and much of the salt has been leached beached frcm from fram the soil response c the 15000 acre feet depletion relates to the total of 22600 acre feet provided by the project for all uses it would be distributed as follows irrigation 2800 industrial industria indu stria 1 6400 municipal 4000 and reservoir evaporation 1400 totaling 14700 acre feet the mean annual unreplaced water from storage as determined from the change in content during the operation study amounted to 100 acre feet this was deducted from the 14700 acre feet leaving a net of 14600 acre feet depletion which was rounded to 15000 acre feet as shown in the statement although the various uses each deplete a share of the water and thus increase the concentration the bureau of reclamations present position is that the right to diversion and depletion of streamflow stream flow carries with it the corresponding right to concentrate the salt load of the stream without penalty the necessity to determine the amount chargeable to each use is therefore questionable even though the break down of depletion is known response d the amount of additional salt contributed by the munici pal and industrial sources on this project if any would be very small and was therefore considered negligible the concentration of return flows from municipal and industrial uses is generally higher than the diverted water from the river due to depletions but the change in load is dependent upon whether salt is added or depleted from the water some industries may deplete the salt along with the water such as powerplants power plants others may add some while others may just deplete part of the water concentrating the remainder with no change in salt load some of the industrial water may be used by the stauffer chemical chemicalcompany company which would deplete both the salt and water other industrial users may also have no discharge and since salt pickup from municipal use is generally small no change in salt loading was assumed for municipal and industrial use comment the statement should indicate what measures will be under taken to minimize the salinity impacts from irrigation response salinity impacts from irrigation of the project lands will be minimized due to omission of salt laden lands from the project and investigations into possibilities of improving irrigation systems and irrigation methods As part of the colorado river system this area is also a part of the basin wide program for salinity control and if investigations show control of the salinity to be feasible the methods will be instituted following is a description of the development of the basin wide water quality improvement program for salinity control of the colorado river authorizing legislation for the colorado river storage project public law 84 45 directed the secretary of the interior to continue studies 173 1 73 |
