<br />SUMMARY AND CONCLUSIONS
<br />
<br />1. The Colorado-Big Thanpson Project, consisting of three reser-
<br />voirs, t~o collection canals, one po~er plant, and one pumping pl~nt and
<br />canal on the Western Slope, a thirteen mile tunnel through the Continen-
<br />tal Divide, and three reservoirs, together with inlet and outlet cane,ls
<br />and five power plants on the Eastern Slope, will divert 310,000 acre-feet
<br />of water per amum from the headwaters of the Colorado river to the South
<br />Platte basin in Northern Colorado. The water so diverted will be utilized
<br />for the generation of hydro-eleotrio e'nergy and to relieve existing irri-
<br />gation water shortages.
<br />
<br />2. Following is a list of plant capacities and heads, assuming the
<br />projeot to be oonstruoted and operated in such a way that,all the firm
<br />energy generated oan be used for a oommeroial load having a load faotor
<br />of 52%.

<br />3. The estimated oost of oonstruction of the basic projeot as made
<br />by the U. S. Bureau of Reolamation on June II, 1939 is $54,288,000. The
<br />total estimated oost of the projeot, including the oost of providing
<br />peaking faoilities on the eastern slope, as IDBde by the ~riter last 'year,
<br />is $58,401,000, using the estimated cost of the basic project as made by
<br />the Bureau. The cost of the project for the purposes of thi s report is
<br />estimated at $65,000,000, the increase being due to the estimated in-
<br />orease in oonstruotion costs during the past year. Of this amount
<br />$25,000,000 of the cost is allooated to irrigati on and the balance of
<br />$40,000,000 will be allooated to pO~er.
<br />
<br />4. The average net annual amount of energy that can be generated
<br />by the projeot for suoh a period as 1902-1941, inclusive, is 876,500,000
<br />kilowatt-hours. This inoludes the amount of energy thl't oan be generated
<br />by the Use of Big Thompson water on the Eastern Slope and exoludes the
<br />!Ul1ount of energy required for pumping water from Granby reservoir to
<br />Shadow Mountain. The maximum amount of energy that oan be generated for
<br />anyone month during the period of minimum stream flow 0 f reo ord is about
<br />40,000,000 kilowatt-hours. This, or 480,000,000 kilowatt-hours per annum,
<br />is taken as the amount of firm energy that can be generated by the pro-
<br />jeot, assuming no, help by steam, Historioal reoords of run-off in the
