XXXVI LETTER OF TRANI:SMl'l"!'AL we,re n.lmost identiclll. Furt.her, the indicated J'eduction in t.he smount. of debi tAree wat.er in stora,gc at. the end of the study period is not necessllrilv fLn indication of injury to C010l'lldo. The qlH'st.ion of actual injllry rests upon water-suppl.y conditions wllich prevail in the yenl'~ subsequent. to those studied. The importnnt faet is t.llat the water supplies avnilable to Colorado Inml. is impro\"ed by the New Mexieo project. On the ot.her huntl, the report. shows that condit,ions in t.be middle Rio Grflnde Volley will he gJ'Plll.ly impro\"cd hy t',onstruction of the proposed New l\fexico project (assuming in eoch insLn.nce that. t.he Colorado project is construded).

In t.he report there hns been an nttf.'nlpt to eOlllputc combined costs nnd henefits of the flood-conLrol nnd rcclamutrion phuscs of the projl'C:t. New 1-[exieo submits that. computltt.ion of benefits for the reclalll:l.tioll phase and for thc Hood-control phase cnnnntr IlI~ reeonci]('d because of t.he pI'e\'!liling difference in policies of the t.wo departmeHts. The attempt to cCJ111bine the ecoIlomics of t,he two phuses hus re~ulted onlr in confusion and should not have heen undertaken. [;.
