<br />Colorado River basin below Hoover Dam receiving water
<br />from and returning water to the Colorado River, is located
<br />along both sides of the Gila River beginning about 15 miles
<br />east of the City of Yuma and about ten miles east of the
<br />confluence of the Colorado and Gila Rivers and extends
<br />easterly for approximately 40 miles. , Development of ,the
<br />Wellton-Mohawk division is limited by law to 75,000 acres,
<br />or such number of acres as can be adequately irrigated by
<br />the beneficial consumptive use of no more tban 300,000
<br />acre-feet per annum of water diverted from, the Colorado

<br />12 Project water for both divisions of tho Gila Project is diverted at rm~
<br />perial Dam. Colorado River water is ,taken at the dam's east .abutment'
<br />through the Gila Desilting Works into the Gila Gravity' Main Canal. The
<br />water flows generally southeasterly. for about 15 miles to a point where the
<br />Gila Gravity Main Canal COllnects to the Wellton-MQhawk Canal. The latter
<br />canal then carries the water up the Gila Valley on a ,course generally parallel
<br />to the Gila lUver to a 'point southwest of Wellton. Here tho Wollton Canal
<br />takes water from tho 'Wel1ton~Mohawk Canal ,about a half-mile above its
<br />terminus and flowa by gravity f'Ol'; about_ 20 miles to, a point near the' foot
<br />of Antelope Hill, six miles northeast of W_ellton, At the terminus of the
