Those three <br /> <br /> <br />reaches are the White River upstream from Meeker, CO; <br /> <br /> <br />the White River in Utah, and the Colorado River from <br /> <br /> <br />Rifle to Gunnison River. <br /> <br />v- <br /> <br />-'<7' In the case of the White River, both in Colorado and <br /> <br /> <br />in Utah, no decisions should be made regarding addi- <br /> <br /> <br />tional storage and/or distribution facilities without <br /> <br /> <br />detailed study of possible impacts on fisheries and <br /> <br /> <br />recreation potential. The same considerations apply <br /> <br /> <br />to the Colorado River and tributaries in Colorado. <br /> <br />~ <br /> <br />5. Supporting Data for Impact Analysis <br /> <br />Tables (Z) and Zl) in attachment J are summaries, as their titles <br /> <br /> <br />indicate. They display the mean percentages of WUA's for the <br /> <br />various 1 i fe stages of target species as compared to the maximum <br /> <br /> <br />WUA's for a given life-stage and species in a particular reach of <br /> <br /> <br />streams. These means, for median years and dry years, are used to <br /> <br /> <br />determine the percent of change, plus or minus, from a basic set of <br /> <br /> <br />conditions, in this case, the MWO (1979) level of development and <br /> <br /> <br />dep 1 et ions. Obviously, behi nd each of these means is a range of <br /> <br /> <br />percentages, one for each month of a cri ti ca 1 1 i fe-stage peri od. <br /> <br /> <br />These monthly percentages were displayed in tables (X) and Xl) in <br /> <br />the discussion of present conditions. Similar tables were prepared <br /> <br />70 <br />
