Colorado-Big Thompson project

Colorado–Big Thompson project,

constructed by the U.S. Bureau of Reclamation to divert water from the headstreams of the Colorado River to irrigate c.720,000 acres (291,400 hectares) of land in NE Colorado and to supply power; built 1938–56. Water is diverted by several dams, notably Granby Dam on the Colorado and Green Mt. Dam on the Blue River. Water is stored in Granby Reservoir, Shadow Mt. Lake, and Grand Lake before it is pumped through the Alva B. Adams Tunnel (13 mi/21 km long), to fall down the eastern slope of the Continental Divide into the Big Thompson River, a tributary of the South Platte. Dams near Fort Collins and Estes Park divert the water for use. Flatiron, Estes, Pole Hill, and Green Mt. dams generate hydroelectric power.

Million estimates the Green, even though it runs mostly outside the box of Colorado, could yield the state 250,000 to possibly even 450,000 acre-feet of water, an amount that is larger--and potentially double--the state's largest existing trans-basin water diversion, the Colorado-Big Thompson Project, which yields 213,000 to 225,000 acre-feet.
(21) Indeed, Reclamation officials, to the frustration of Secretary Ickes, supported congressional measures exempting two projects from the 160-acre limitation: the Colorado-Big Thompson Project in Colorado in 1939 and the Truckee Project in Nevada a year later.
First, in 1939, the Colorado-Big Thompson Project was exempted from acreage limitation, and Representative Elliott's use of that exemption as a guide in drafting the one for the CVP probably influenced their support.
Daniel Tyler documented the Northern Colorado Water Conservancy District's continual struggle to secure construction and operation of the Colorado-Big Thompson Project according to its 1938 contract,(38) which guarantees Northern a perpetual right to the project's water yield and was written before adoption of the 9-E water service contract.

The Colorado-Big Thompson project is the biggest of these.
The Colorado-Big Thompson Project (C-BT), for example, was sponsored by farmers and cities who had experienced the Great Depression and devastating Dust Bowl drought of the Thirties.(12) In those days, the national government invested in the livelihood of citizens and the infrastructure of the nation, instead of obstructing both.
