Colorado will expeot the Report to disclose that export diversions <br />i'rom the Colorado River system are limited to quanti ties above mentioned <br />by the construction oosts and repayment requirements of such developments <br />but that substantial~ gl"eater amounts of water are possible of exp:>rta- <br />tion by means of longer tunnels and gTeater pump-lifts if oonstruction <br />oosts are to be disregarded or materially subsidized. <br /> <br />" <br /> <br />" <br /> <br />50.
