<br />Any probable rate of depletion, Which may be as low as 0.5 acre-feet per ac-
<br />re, indic~tes that an area as 18r~e, perhars larRer, than the area of present hay-
<br />lRnd could be supplied fron a total of 500,000 acre-feet ye~rly. In spite of pro-
<br />paganda for pasture irrig~tion of vast new arens, su~h ir~g~tion will only be
<br />pr3ctised in those favored places where a ver7 8m1ll inves~ent. ample supply of
<br />water and suitable physical fentures will all operRte Rod such acplic$ition of WIll-
<br />er will not CRuse erosion of soil. All these f9ctors, together with the necessity
<br />thl'l.t forage produced shall have economic v21ue, will greAtly loot such irrigation.
<br />~ore detniled infor~1tion from experience will probably accrue very slowly.
<br />
<br />Evapor~tion loss from middle river stor~ge is, in this study ~pportioned
<br />against the states in the r~tio of their scver~l tot~l depletions after ultimate
<br />develop;flnt. In actu-,] pr:lctise this loss '....il1 actu~lly be largely met with Colo-

<br />
<br />By rcfer~nce to the fo~'egoing tnbulation of deli veri nt lee Ferry it would
<br />appear that when u)tim~te development, as visioned in the ~~sin report, has been
<br />brought ~,bout, the ur-per b,qsin would f'lil by 710,370 3cr-e-feet yea.rly, to deliver
<br />at lee Fcr-ry, the ~nr,ua1 .~ount required by the Color~do River Comp~ct, during
<br />the period from 1914 to 1943. Actu311y such (I conclusion is not necessnrily true
<br />but it is necessnry to set up the sc~le of deliveries during the dry deCAde and
<br />m'l.ke use of both, f!1on~ with n 3tudy of operl\tion of middle riv~r storflf!e to
<br />re~ch a correct ide~ of the prob~ble result. Thor~ follows qnoth~r tAbulntion of
