The increased flows, <br /> <br />which averaged about 82,000 acre-feet annually, largely flowed across the <br /> <br />international boundary into Mexico, although a small percentage evaporated and <br /> <br />even smaller amounts were consumed in the Lower Basin (6,000 acre-feet/year at <br /> <br />node 34) or stored in system reservoirs. This finding served as a prelude to <br /> <br />subsequent runs, in which several parameters were varied in an attempt to <br /> <br />determine the sensitivity of the non-use conclusion to potential changes in <br /> <br />future conditions. Although the potential for use of increased flows was the <br /> <br />primary focus of these subsequent explorations, it was not the only conclusion <br /> <br />of interest. As it turned out, other findings emerged which were more <br /> <br />significant. They are reported as well. <br /> <br />Table IV~~r~j~ed Average Annual Colorado River <br />~Cu~ent ,!~O'Demand Conditions (Thousands of <br /> <br />With Existing Interstate <br />Water Allocation <br />Institutions <br /> <br />Water Disposition, <br />Acre Feet) . <br /> <br />~ <br /> <br />Without Existing <br />Interstate Water <br />Allocation Institutions <br /> <br />Natural <br />Flows <br />Only <br /> <br />Flows Augmented <br />by Vegetation <br />Manipulation <br /> <br />Natural <br />Flows <br />Only <br /> <br />Flows Augmented <br />by Vegetation <br />Manipulation <br /> <br />I <br /> <br />Upper Basin <br /> <br />Consumptive Use <br />Evaporation <br />Shortages <br /> <br />3451 <br />752 <br />3 <br /> <br />3451 <br />753 <br />3 <br /> <br />3451 <br />782 <br />3 <br /> <br />3451 <br />782 <br />3 <br /> <br />Lower Basin <br /> <br />Consumptive Use <br />Evaporation <br />Shortages <br /> <br />718~ ./ <br />l47V <br />209' <br /> <br />7195 <br />1484 <br />203 <br /> <br />7398 <br />1524 <br />o <br /> <br />7398 <br />1545 <br />O. <br /> <br />Net Change in <br />Reservoir Contents <br /> <br />-240 <br /> <br />-238 <br /> <br />-197 <br /> <br />-195 <br /> <br />Outflow to Mexico <br /> <br />3536 <br /> <br />3600 <br /> <br />3205 <br /> <br />3263 <br /> <br />. ~. <br />.'r <br /> <br />.f! <br />(~.. <br />1 r;"-/: ,- . <br />l~..-:-f"I j <br />C":' !\~} err"'f !e/li" , ~.o <br />",' r: .: r {11': (1 . fA ,?O 0 \ ~( I.J-'~ <br />I .... .
