<br />(a) Diversions of water in ths Lower Basin to basin of Salton Sea, and to
<br />Pacific Coast drainages in Southern California, and of water from
<br />Colorado Biver to Gila Biver Basin in Arizona, are treated as though
<br />local in character, and are not termed exportations and are not sepa-
<br />rately summarized, as in the Upper Basin.
<br />
<br />6. POWER
<br />
<br />Hydro-electric power is termed one of the most important re-
<br />sources of the Colorado River Basin. At present but a small part of ulti-
<br />mate potentialities have been developed, particularly in the Upper Basin.
<br />Present installed capacities, shown at ~ages 132 and 219 of the Report,
<br />may be summarized as follows (kilowatts):
<br />Hydro- Steam Internal Total
<br />Electric Power Combustion Installed

<br />Note (8): The author of the Upper Basin portion of the Beport
<br />considers only the natural drainage basin of ths Colorado Biver, thus ex-
<br />cluding the drainage area of Bonneville Basin, to the west in Utah, and the
<br />drainages of the Bio Grende in New Mexico and Colorado, of the Arkansas and
<br />Platte Bivers in Colorado, and the North Platte Biver in Wyoming and Colo-
<br />rado, all of which are part of the "Upper Basin", as defined by Par. (a)
<br />and (f), Art. II of the Colorado Biver Compact. Note also that in its
<br />Missouri River Basin Beport, with respect to the State of COlorado, the
<br />Bureau of Reclamation said: "Transmountain diversion projects were not con-
<br />sidered a part of this basin."
