I I I I I I I I I .' I I I I I I I I I B9. Weather M:x:Ii.fication/SurPlus Flows Weather IOOCIi.fication could augment Colorado River watershed rI.U1off by up to about 2,000,000 acre-feet per year. These flows could be used to satisfy ~can Treaty water requiremants. Since ad:li.tional water would be in the river system, the frequency of excess flows could increase and reduce the periods when the YDP production would be required. A 6 to B year inplemantation would be required at a cost of about $26 million. Annual cost of an operational weather IOOCIi.fication program would be about $12 million to $16 million. This augrrentation would allow the generation of about 1.7 billion kiloWatt hours (kWh) of electrical energy equal to about $34 million in pm<er benefits. The ad:li.tional water would reduce the salinity of the water at Inperial Dam by about 110 p/m creating benefits of about $62 million per year. Advantages : o Increases total water SlWly in the Colorado River Basin. o Could reduce the frequency of required YDP operation and reduce the a=:npanying operating costs. o Power benefits would be $34 million. o Salinity benefits would be $62 million. Disadvantages: o Plan nay encounter fonniclable environm:mtal and substantial institutional problems. o Ownership and right to use new water nay be disputed. n ~J '- "\ ~ ';' ,. ~ ... ~ ~ ~:~ ~. .f f" ~~4 :~: )._ t; :~. ;.i.'~ ~: :~ ":~ /~~~ ~ { y 1 '1,,/ ~~ ~'l~.::~ (.~ ~ n ~1 i.:" ?-, ',;~~ I '\. ~ 0\ i ~:'~l L ,_ ;,' u ,.~' .
