<br />. RUEDI DAM AND RESERVOIR, COLO.
<br />
<br />Ruedi Reservoir was considered as the sole source of additional water
<br />.for the Cattle Creek ]n]J(ls. Sourees of addit.ionnl wnte.r considered'
<br />a.vnihble for the Bluestone. area eonsisted of in('reased ret.urn flow
<br />from the Cnt.t.le Creek a rea and releases from Rlledi Resen~oir made
<br />eit.her for the direct. use of the Blllestone lands or to ma.int.ain fish
<br />flows that would be surplus to other existing downstream useS. It
<br />was consic1ered necessary to replaee only the streamflow depletion due
<br />to irrig-at.ion of these la.nds. The remainder of t.he water dh'erted-to
<br />the lallds would return to t.he Colol"n,do Rive.r nnd would be available
<br />to other uses. Results of t.he st.udies. intended onl}' as a rough ap-
<br />proximation of pos,o;;ible nlt.e.111ati\'e il"rigation uses of Ruedi Reservoir,
<br />are summarized in the following ta.bulation in thollsflnds of a.c.re-fee.t.

<br />Although the extent of potential irrigation de\"l;~lopment for the.
<br />1tlonnt Sopris area is not. preselltly known and for that. renson not
<br />I;ollsiclered in the preceding tnbuIatioll: it has been very roughly e.sti-
<br />mated that the lands in that area could require. an average of 3,000'
<br />acre-feet of aclditionul water annually. On this hasis, the total average
<br />a~VlUal :rieh-I required from R.lIedi R.eservoir for alternat.ive irrigation
<br />us"ge, ,,"ould be in the neighborhood of 4.4,000 aCTe-feet.
<br />The dependable annual yield of w"ter from Ruedi Reservoir wouhl
<br />var.\~ son~ewhat depending upon the pa ttern of water usage and the
<br />availability of water from other spllrces to assist in meet.ing demands.
<br />If the reservoir were operated :jOlely to supply lOCH] irrigat.ion de-
<br />mands, it is estimated t.hnt the total average yiel,' of the reservoir
<br />woul,l bel)Ollt (;2,000 acre-feet ,mnna11v.
<br />Bnsed !ihe nbove figures, it appe,;rs that. Rnedi Reservoir could
<br />yield Hn ,..a!l"e of about 18,000 acre-feet of water in excess of require-
<br />ments of the' Cat.tle Creek, Bluestone, find 1\.Ionnt Sopris areas. De-
<br />taileo ~t.udies, however, might show t.hat the water rel]uirements for-
<br />the three areas would be eit.her significantly lower or higher than!
