The relationship <br /> <br />indicates that for changes in storage greater than about +1.4 <br /> <br />million acre-feet (maf), there is a net gain of salt while for <br /> <br />changes in storage less than +1.4 maf, and for negative changes in <br /> <br />storage, there is a net loss of salt. <br /> <br />In the 1975 and 1978 Forum salt routing studies, it was <br /> <br />assumed that there were no salt gains or losses in Lake Powell. <br /> <br />The relative impact on projected salinities of including this <br /> <br />relationship in the routing studies is difficult to evaluate without <br /> <br />additional computer runs. However, in general, salinities would be <br /> <br />less than previously estimated for the low virgin flow rates and' <br /> <br />greater than previously estimated for some of the high virgin flow; <br /> <br />rates used in the Forum studies. <br /> <br />Bank Storage <br /> <br />The amount of water going into or coming out of bank storage".. <br /> <br />,:- . <br />1.,.", <br />
