<br />7. This item in your analysis relates to Western Colorado present
<br />uses of water from the Colorado River, which you state to be 544,000.acre-
<br />feet annually. Unlike estimates for potential uses of water, ~his item is
<br />not concerned vdth policies, legal interpretation of pertinent documents,
<br />or future surveys and investigations. It is susceptible of reasonably
<br />3.ccura.te determination on the basis of existing records and anticipated
<br />2'xportationof water by authorized Federal projects . Accordingly, the
<br /><:>-(;,aff of the ~later Board, at my request, has made certain estimates herein-
<br />after set forth for the purpose of comparison with the figures which you
<br />include in your analysis. Your figure is taken from the Bureau of Reclama-
<br />tion Blue Book, p. 186, Table CXXI (it is the sum of 102,300 and 442,000 and
<br />accurately should be 544,300). You erroneously state that in the computation
<br />of such figure the Colorado-Big Thompson use is figured at 310,000. The text
<br />shows (Blue Book, p. 126) that the Bureau used the figure o~ 32.0,000 for the
<br />CCJlorado-Big Thompson. An analysis of the Blue Book tables on pp. 130, 138,
<br />3.!ld 151 shows that the Bureau figure for present exportations is computed as
<br />fol101l'Js:

<br />Present estimates of the engineering staff of the Colorado Water
<br />Conservation Board on annual exportations f'rom the Colorado River system in
<br />Colorado are as follows:

<br />Comparing your figures under Item 6 and 7, with those contained
<br />herein under paragraphs 6 and 7, it appears that your figure of 1,673,000
<br />acre-feet, as the total present annual Colorado uses, is too high by 144 ,513
<br />acre-feet a year, as shown by the follordng table:
