An <br />annual potential Itreastlow augmentation of 1,315,000 acre-feet i. <br />pO'lible in the Upper B..in, 298,000 acre-feet in the Lover Ba,in <br />Ind 467.000 acre-feet to u.mediately adjoining ba.in. cau.ed by <br />aeeding mouDtain ranges between ba.ins. During the reco~nded demon- <br />stration progra., an average annual augmentation of about 850.000 acre- <br />feet would result. Total 14-year augmentatioD would be about <br />12.000,000 acre-feet for the Colorado and adjoining river basins. <br /> <br /> AveraRe Annual ~ater AURmentation <br />1980 108,000 .-f 1987 1.200,000 .-f <br />1981 312,000 1988 1,200,000 <br />1982 492,000 1989 1,200,000 <br />1983 756,000 1990 1,092,000 <br />1984 1,200,000 1991 888,000 <br />1985 1.200.000 1992 708,000 <br />1986 1.200,000 1993 ~,OOO <br /> <br />This water augmentation. floving through existing Reclamation hydro- <br />electric planta, would produce 600. to 900-.illion kilowatt hour. of <br />..rketable energy annually with. value of up to $S .111ion per year <br />at latest power rates.
