<br />000017 <br /> <br />", <br /> <br />COLORADO-BIG THOMPSON PROJECT (1) <br /> <br />The Colorado-Big Thompson Project will provide a supplemental <br />water supply to approximately 615,000 acres of land now under culti- <br />vation and will develop electrical energy for resale to consumers <br />and distributing agoncies in Colorado, Wyoming, and Nebraska. The <br />combined generating capacity will be approximately 176,000 kilowatts. <br /> <br />The key feature of the preject is the Alva B. Adams Tunnel <br />which pierces the backbone of the Rocky Mountains for a distance of <br />13.1 miles between Grand Lake, Colorado, and Estes Park. It is <br />through this tunnel that stored water from the western slope water- <br />ahed will bo diverted to the eastern slope for irrigation and power <br />purposes. <br /> <br />The largest reservoir on the project, Granby Reservoir, is <br />located on the western slope of the Colorado River and will store ex- <br />cess runoff, which will later be pUlllped through Granby pumping plant <br />into Shad""" Nounta in Lake. From Shadow Mounta in Lake, the pumped <br />water, together with additional water flowing therein, will flow by <br />gravity through Grand Lake and thence into the Alva B. Adams Tunnel <br />and under the Continental Divide to the eastern slope. <br /> <br />" <br /> <br />Two lerge reservoire, namely, Horsetcoth Reservoir and Carter <br />Lake Reservoir, with a combined capacity of 256,000 acre-feet, will <br />be used for storage of water preparatory to release for irrigation <br />purposes. Water will be roleasod from these two reservoirs through <br />supply canals into the Pudre River, the Big Thompson River, St. <br />Vrain Creek, Boulder Creek, and the Platte River. <br /> <br />Green Hountain Reservoir is lGeated on the Blue River, a <br />tributary of the Colorado River on the western. slope. Water stOI'ed <br />in this reservoir will provido a continuous and uninterrupted flow <br />of water which might otherwise. have beep interferred with as a <br />result of the diversion process. <br /> <br />Power plants of the ~jeet will be interconnected with power <br />systems of the North Platte, Kendrick, Rivert~n, and Shoshone Proj- <br />ects in addition to n1llllCrous privately and publicly-owned systems. <br /> <br />The program for fiscal year 1948 for the entir~ Colorado-Big <br />Thompson Project is $19,200,782. <br /> <br />M:::jor features of this projeet are discussed in more detail on <br />subsequent pages. <br /> <br />27 <br />
