<br />" <br /> <br />line provides the same information for 2020 conditions under the "most likely" <br />future depletions. Similar information is presented on Exhibits 10 and 11 for <br />Garrison Uam and 12 and 13 for Oahe Uam. These exhibits dcmonstrate that <br />storage regulation of pre-Pick-Sloan-Plan flows is necessary to provide assured <br />flOl's for not only future conditions of water use, but for current use as <br />well. TIlis is true even if flows ,;hich occurred during the 1930's drought <br />(indicated by asterisks) are ignored. <br /> <br />CO:-;CLUSIWS I <br /> <br />The watcr supply of the ~lissouri River, as 1'eguI:lteu b)' the main stem nnd tl"ibU~';',lJ <br />reservoir system, is :Jdeql1:Jtc to meet all beneficial consllmptive uscs ",hich h,',\," <br />been considered in r.n)' water resource ,\evelopment plan considered to date, <br />including thc p!'ojected ultimate u~e of up to 3 million acre feet of "tater an"ualJ <br />for deve lopffient of the coal resources of the upper b:Jsin.
