<br />1 <br /> <br />THE RIVER AND THE PEOPLE <br /> <br />By A. B. WEST, Regional Director, Region 3 <br />U. S. Bureau of Reclamation, Boulder City, Nevada <br /> <br />I am pleased to be here with the members and friends of the Colorado River Water Users <br />Association on the occasion of its Silver Anniversary. As you are all aware, Region 3 of the Bureau of <br />Reclamation has been the Federal office most deeply involved in the development of the resources of <br />the lower Colorado River. It has been our goal to achieve a balanced river management program that <br />recognizes and serves the overall needs of the people who depend so much on the river. Since you in <br />the audience represent those people, or are very closely associated with them, I am particularly pleased <br />to have this opportunity to tell you how our work is progressing. <br /> <br />The early period of river management in the decade of the Thirties was devoted to planning <br />and building of dams. Now, our river management activities consist of two principal phases, The first <br />is to control the water flowing in the river. This is accomplished through an increasingly scientific <br />coordination of supply and demand. This coordination has reached a new high level of efficiency in re- <br />cent years. Senator Wash Reservoir and pumping plant, near Imperial Dam, has been a major contribu- <br />tor. It permits water users to order water more realistically and lets us schedule riverflows much more <br />closely without fear of causing shortages in deliveries. It also makes it possible for us to place in stor- <br />age a portion of the excess flows resulting from storm runoff and reduced water requirements during <br />and following storm periods. The records show that the unscheduled excess deliveries to Mexico have <br />been reduced appreciably during the past 3 years. In 1963, 1964, and 1965, they ranged from 119,000 <br />to 332,000 acre-feet per year. In 1966, 1967, and 1968, they ranged from a high of 44,000 acre-feet in <br />1966 to a low of 20,000 acre-feet this year. <br /> <br />The second principal phase of our river management activities is the control and stabilization <br />of the river channel, which affects your future supply of water and your present daily operations. <br /> <br />Reclamation's multiple-purpose river management program began near Needles in 1946. That <br />work in the Mohave Valley Division was an emergency response to a condition of chronic flooding, As <br />the work got underway the value of water salvage was recognized and was adopted as a project goal. <br />Wildlife and recreation values were considered in this work, but the measures which were included in , <br />the original project for fish, wildlife, and recreation were only a beginning when compared to Recla- <br />mation's current work. <br /> <br />I <br />I <br />.1 <br /> <br />.1 <br /> <br />At the present time, Reclamation has spent $8,200,000 in the Mohave Valley Division. Of <br />this amount, $827,000, or about 10 percent, was for wildlife and recreation features. Water salvage in <br />the Division amounted to 109,000 acre-feet per year. Of this, about 65,000 acre-feet have been sal- <br />vaged. The remaining 44,000 acre-feet are contingent on future maintenance which we had planned to <br />carry out in the Topock Gorge. Additive to this is the potential salvage of 28,000 acre-feet by work in <br />the Topock Gorge Division, Our Palo Verde Division river management work extends from the Palo <br />Verde Diversion Dam to Taylor Ferry south of Blythe, California. The work in this Division is virtu- <br />ally, complete. It consisted of stabilizing the river channel by narrowing wide reaches of the river with <br />gravel and rock training structures and by armoring, eroding sections of the natural riverbank with <br />quarried rock, Many backwater areas were created by this work, and in cooperation with the Arizona <br />Game and Fish Department, the California Department of Fish and Game, and the Bureau of Sport <br />Fisheries and Wildlif~, we are striving to provide facilities which will make the most of the fish and <br />wildlife resources of the Division. We have installed 17 pipe structures to insure fresh waterflow in the <br />backwaters as provided in the original project plan. Cooperative efforts to deepen these backwaters to <br />provide benefits beyond those called for by the project plan have been slowed by our budget prob- <br />lems this year. We hope soon to reactivate this work, <br /> <br />Our completed work in the Palo Verde Division has cost $2,900,000 with $134,000 or about 5 <br />percent of this for recreation and wildlife features. Water salvaged was 10,000 acre-feet per year. The <br />work also reduces the sediment inflow into the Imperial Division by 310,000 tons per year. <br /> <br />The Cibola Division is just downstream from the Palo Verde Division and extends to the lower <br /> <br />-24- <br />
