<br />Sever8.l times in the past. few year s we have rushed emergency <br />flood~fighting teams to areas threatened by floods, pllincipally in the <br />Upper Ballin. Fortunately, during the past .eason, there were no floods <br />or disasters in. the Colorado River Basin. l-Jowever, we stand ready at <br />any time to perform emergency work. <br /> <br />*- <br /> <br /> <br />Another project authorized several. years ago, for Tucson,Arizona, and <br />vicinity, has been recommended for de4author,ization because 10c8.l in- <br />terests have constructed a project that provid~s much of the protection <br />that would have been provided by the Federal project. Congress,this year <br />authorbed a flood-control project for lower Agua Fl:'ia River and vicinity, <br />Arizona. . <br /> <br />l!; <br />t;: <br />( <br />t. <br /> <br />None of these authorized projects are under construction. However, <br />civil planning funds have been made available for Painted Rock Res.ervoir <br />and Air Force planning funds for the project on Agua Fria River. Plan- <br />ning for these projects will continue during the fiscal year. Construction <br />(tentatively scheduled fol:' initiation in c8.lendar year 1955) is dependent <br />upon funding. Plans and specifications for Trilby Wash Detention Basin <br />are scheduled for completion 15 January 1954. The plan provides for the <br />detention basin on Trilby Wash, and an outlet : channel to convey flood <br />releases to Agua Fria River. Trilby Wash Dam would be earth-fill <br />49,500 feet long, and 34 feet high, with a Z, OOO-foot spillway at the left <br />abutment. The improvement, estimated at $3,000,000, would provide <br />protection fo!;' military installations, 3 town.s and 50,000 acres of <br />cultivated land. <br /> <br />For Painted Rock Dam foundation explorations are practically <br />completed, and detailed planning studies are peing pushed for the embank- <br />ment and the spillway. General design studiEiS, which precede plans and <br />specifications, are scheduled for completion l.n July 1954. This dam <br />would be earth-fill 4,470 feet long and 174 feet high. The resel:'voir <br />capacity would be Z, 480, 000 acre-feet, including ZOO, 000 l:'eserved foi:' <br />sediment. The improvement, estimated at $35,000,000 wouldprovide <br />flood protection along Gila and lower Colorado Rivers, arid in Imperial <br />Valley. <br /> <br />Another indication of our future plans in your behalf is the large <br />backlog of Colorado River Basin authorized flood~control investigations. <br />Little money has been available for these investigations for several years - <br />none during the past lZ months. The investigations include: <br /> <br />~. <br /> <br />f <br /> <br />Preliminary examinations of CC)lorado River and <br />tributaries above Lee Ferry, and Las Vegas Wash <br />and tributaries; <br /> <br />Surveys of Virgin River and triputaries, Animas <br />River, Kanab Creek, Dolores and Dolores River <br />Basin upstream from Dolores, land Gila River and. <br />tributaries; and . <br /> <br />Review of the report on Lit1;le Colorado River (Gallup). <br /> <br />... <br />.. <br /> <br />-Z- <br />
