<br />General
<br />
<br />'lliis is the ninth Annual 4Jerating Plan for the Fryingpan-Arkansas
<br />Project, which, when oonpleted will ronsist of federally owned dams,
<br />reservoirs, canals, exmduits, tunnels, purrping plants, hydroelectric
<br />p:lWerplants, electric transmission lines, substations, and other facil-
<br />ities. As indicated by the enclosed project map, these features are, or
<br />will be, located in the Fryingpan River and Hunter Creek drainage areas
<br />of the Cblorado River Basin and in the Arkansas River Basin, central and
<br />southeastern Cblorado, respectively.
<br />
<br />These extensive ~rks will ultimately make possible the orderly and
<br />beneficial use of water for i=igation, hydroelectric J:X)I>Jer generation,
<br />fish and wildlife preservation, and rmmicipal and industrial uses, and
<br />provide flood oontrol and other collateral benefits.
<br />
<br />.
<br />
<br />'!he purpose of this report is to provide a basis for increased cooperation
<br />and understanding arrong all ooncemed with the roordinated operation of
<br />the Project.
<br />
<br />'!'he FIyingpan-Arkansas Project was authorized lIDder Public Law 87-590,

<br />
<br />'!he Bureau has OOIlIpleted several operation studies on Ruedi Reservoir by
<br />asslilling various agricultural, municipal, and industrial demands.
<br />Depending up:m the assured demand, the average annual yield of the
<br />reservoir varied fran 64,000 to 78,000 acre-feet. 'Il1e present estimate
<br />of the replaC€!lEl1t requirerrent is about 28,000 acre-feet annually and the
<br />average annual marketable yield is estimated to vary from 36,000 to 50,000
<br />acre-feet. '!he Bureau is refonnulating the W:!st Divide Project to utilize
