<br />River Compaot upon the States of the Upper Division, it follows that the
<br />said initial list of Upper Basin projects oan be authorized and oonstruot-
<br />ed without danger of violating the said delivery obligation, and without
<br />requiring the construotion of any of the potential main-stem power, regula-
<br />tion or replaoement reservoirs listed in the Report. Colorado suggests,
<br />that the Report be &mended to ino1ude the analyses and oOlllllents, above out-
<br />lined. In conneotion with said initial list of projeots, it should be
<br />noted that Colorado has approved the plans of the Littie Snake Projeot only
<br />to that first stage of its development whioh is presently needed, and Oan-
<br />not now approve the plan for full or ultimate development; and Colorado
<br />suggests that the potential San Juan-ChAma diversion projeot be exoluded
<br />from said initial list 0 f proj ects am not be ,oonsidered until such time
<br />as investigations permit seleotions to be made by New Mexioo; and that an
<br />agreement with Colorado will be neoessary at that time.

<br />listed in the Report are estimated therein at 1,851,000 aore feet annually.
<br />Independent estimates by Colorado engineers arrive at substantially the
<br />same total for the entire Upper Basin, but disolose rather wide discrep-
<br />ancies when the estima~ed depletions are segregated by States, as indioat-
<br />ed in the following table.
