<br />istration of water
<br />distribution, Progressive step. in legislation iinally
<br />led, in 1922, to the signing of tbe Oolorado River
<br />Compact, which aPportioncd S'ven and a half million
<br />acra-f,et annuaUy to tbe upper basin States comprising
<br />Wyoniing, OOlorado, Utab, and New Mexico, Later,
<br />tbe BQUlder Oanyon Act provided funds for determin_
<br />ing th~ amount of lands tbat Were or Could be irrigated
<br />in tbeiColorado River Basin, Information obtained
<br />from these .tudies revealed tbat in.sulllcient irrigable
<br />land. ""isted in tbe Oolorado RiVer BllSin to utilize all ,
<br />of the \vater pronded in tbe compact, It Was tbere_
<br />fora on(y lUltural to conceive a plan Wbereby surplus
<br />Colorado River waters could be diVerted into otber
<br />watersbed. in nortbea.tern Oolorado wbere tbere was

<br />investigations of a transmountain project to divert
<br />Water froin tbe Colorado River Basin on the western
<br />slope of the Continental .Dividc to the eastern slope,
<br />After mo';. tban two Years of extensive study, a plan
<br />w'" developed wbicb contained features for diverting
<br />
<br />tbe irrigation water from tbe western to the ea.tern
<br />slope, features for Controlling western slope flows so
<br />as to guarantee existing water rigbts in tbe Colorado
<br />River Basin, and features to talre adVantage ef natural
<br />epportunities to develep bYdreelectric Power. The
<br />project plan has been reviewed by many consnlting

<br />Detailed planning studies Were continued while

<br />,otber reservoirs Wera added to or dropped from tbe
<br />' plan, PllJ't of tbe eastern slope routing Was cbanged, and
<br />furtber pOWer in.stallations have been .dded, Tbe
<br />Green Mountain Dam, first to b. constructed, Was
<br />completed in 1944, the Sbadow Mouutain Dam Was
