Show 11 Major tributary systems exist in every Basin state except California. The most important of these systems are: the Green in Utah, Colorado and Wyoming; the Gunnison in Colorado; the Dolores in Colorado and Utah; the San Juan in Utah, Colorado, New Mexico and Arizona; Johnson and Kanab Creeks in Utah and Arizona; the Little Colorado in Arizona and New Mexico; the Bill Williams in Arizona; the Gila in Arizona and New Mexico; and the Virgin in Nevada, Utah and Arizona. Of these, Johnson and Kanab Creeks, the Little Colorado, the Bill Williams, the Gila and the Virgin are within the Lower Basin of the Colorado River.28 The Little Colorado River, which drains 26,930 square miles, Kanab Creek, which drains 2,200 square miles, and the Virgin River, which drains 11,000 square miles, all flow into the main Colorado River above Hoover Dam.24 Both the Bill Williams, which drains 5,400 square miles, and the Gila, which drains 57,800 square miles, flow into the River below Hoover Dam.26 A canyon section, approximately 1,000 miles long in southern Utah and northern Arizona permits a convenient division of the Basin into two parts, an Upper Basin and a Lower Basin. The Colorado River Compact defines the Upper Basin as the parts of the Basin "within and from which waters naturally drain into the Colorado River System above Lee Ferry," and the Lower Basin as that part of the Basin "within and from which waters naturally drain into the Colorado River System below Lee Ferry." Lee Ferry is defined as a point on the mainstream of the Colorado River one mile below the mouth of the Paria River.26 a»Ariz. Ex. 1000, p. 9. 2*Ariz. Ex. 1000, p. 11. "Ariz. Ex. 1000, pp. 11-12.
