NOTE (12)1 In the Colorado statement of July 20, 19Ui, the total exportations of all oonstructed enterprises and their ::-robablQ extensions. and all projects \Ulder construction and authorized and all contem- plated and possible future projects, was estimated at 2.000.000 a.ore feet in a year of normal precipitation and runoff. Of this total the completed enterprises and those under construction were estimated at 445,700 acre feet. and all others at 1.554.300 acre feet. These othar projects might divert. during a drouth cycle such as 1931-1940, perhaps 1,240.000 acre feet, - a figure com- parable to the 1.036,600 acre feet given in the Report for poten- tial exportations. In brief, the Bureau has excluded about 200.000 AF (drouth oycle) or 250.000 AF (normal) of the exporta- tions in Colorado which heretofore have been considered probable or pos sib Ie. , NOTE (13), In connection with the potential exportation projects in Colorado particularly the Blue-South Platte and Gunnison-Arkansas. the Bureau of Recllllllation has included the cost of power and other fa.oilities in the importing basins, but has not included eithar the quantities of power generated or the areas of land benefited by such projects. This results in a distorted picture. and. when the South Platte and Arkansas River Basin Reports are prepared,' will result in duplicntion and confusion. It is recommended that estimated costs be revised to include only the west slope features. or that the power produced and the areas benefited in the import- ing basins be included, along with total costs, as though a part of the Colorado River Basin, which by the Compact they are. .
