<br />Irrig~tion facilities for lands along the Blue River below Green
<br />Mountain Dam. and along the Colorado River betwe;en Granby Dam and
<br />Kremmling hajve been improved or replaced so that an adequate supply
<br />of water can b:e assured at all stages of river flow. These win be de-

<br />Gran~y Reservoir, having a total capacity of 540, 000 acre feet,
<br />serves as the principal storage reservoir in which surplus water origi-
<br />nating on the headwaters of the Colorado RiVer is stored prior to diver-
<br />sion. Water f~omWillow Creek is regulated, stored, and delivered to
<br />Granby Reservjoir through Willow Creek Reservoir, Pumping Plant, and
<br />Canal. From Granby Reservoir, the water win be lifted a maximum of
<br />186 feet by me~ns of the Granby Pumping Plant into the Granby Pump
<br />Canal and then~e into Shadow Mountain Lake, contiguous to Grand Lake,
<br />a famous naturf'll feature. The water will then flow by gravity from Grand
<br />Lake through t>>.e Alva B. Adams Tunnel, which is 13.2 miles long, under
<br />the ContinentaliDivide to the Eastern Slope where it win pass through a
<br />series of cond~ts, tunnels, penstocks, and power plants, and win be
<br />stored in Carter Lake and Horsetooth Reservoirs. During the irrigation
<br />season, water Win be released from these reservoirs through the Poudre,
<br />North Poudre, St, Vrain, Boulder Creek, and South Platte Cap.als to the
<br />Cache la Poudr~, Big Thompson, Little Thompson, and South Platte Riv-
<br />ers, and St. Vrain and Boulder Creeks. From these natural \vater
<br />courses, the water will be diverted into existing irrigation canal systems
<br />for delivery to ~he farm lands.

<br />The prpject plan also provides for installation of hydrogenerat-
<br />ing equipment h~ving a total capacity of 177,650 kilowatts and appurtenant
<br />switchyards, tr$nsmission lines, and substations to deliver the generated
<br />energy to the power market area. .
<br />
<br />Briefly; the project is comprised of 13 reservoirs and regulat-
<br />ing basins, 23 e$rth and rock-fiU dams and dikes, 6 power plants, 3 ma-
<br />jor pumping plants, 24 tunnels, 11 canals, 16 major siphons, 8 pen-
<br />stocks, 785 circuit mUes of transmission Hnes, and 36 substations and
<br />switchyards. P~rtinent detailed data concerning these features are shown
<br />in Tables I through V,
<br />
<br />Constru:ction of the project is scheduled for essential completion
<br />by 1955. The to~al estimated cost of the project is $160,068,000 with
<br />allocations of $9t 878, 000 to irrigation, $60, 757,000 to power, and
<br />$1,433,000 reimpursable from other projects. The reimbursable costs
<br />of the project wi~l be repaid through power revenues and assessments
<br />of water users.
