<br />Now with sip,nificant upstream re~ulntion, the Hureau's anility <br />to I'red1ct levels and the magnitude of annual fluctuntion tnllLe~ it <br />easier for the concessionairea to operate their facilities. <br /> <br />Occasional problems at particular water surface elevntions mokes <br />it necessary for some concessionaires to move their facilities, <br />although the need to move doea not occur simultaneously at all <br />concessions. Information on current and projected water levels is <br />provided to conceasionaires by telephone from the [lureau' s linter <br />Scheduling nranch. This method of notlficn ti on has arpn rently been <br />aatisfactory to the concessionaires. <br /> <br />Scheduling of releases and. the rnap,nltude of releases from <br />Lake Powell also have a real impact on ti,e operation of the conce6sion- <br />aire facilities at \,ahweap and Bullfrog Lasins on Lake Po",el1. The <br />concessionaire relies heavily on the projections of ",ater aurface <br />elevation and seasonal change thereof in plann1ng for a successful <br />operation. <br /> <br />C. Recommendations <br /> <br />Because of the multipurpose aspects of Colorado River reservoir <br />operation, a high degree of coordination must be rnainta1ned. Requests <br />for expanded coordination have been made by fish and game agencies in <br />order to help enhance Lake Mead's Lass fishery. Requests have also been <br />made by the Hoover Dam energy allot tees for a study to improve the <br />pB t tern of energy deliveries from Iloover Dam. The Ilureau of ReclamatJ.on, <br />as the agency having primary responsibili ty for operating the <br />Colorado River I B reservoirs, welcomes recommendations for imrrovln~', <br />coordination between it and these agencies. <br /> <br />Recommendations leading to more beneficIal management of the lake'a <br />resourcea may include: <br /> <br />1. A pre- and a post-spawn meetinp, ",ith interested ap,encIes <br />to be held in Boulder City each year. These meetings <br />would be to discuss and explain proposed operntionn, to <br />evaluate the need for schedule modification, and to <br />present data on ongoing spawning studies. <br /> <br />2. Monthly schedules of projected Lake Mead elevations, based <br />on the best data available will be transmitted to interested <br />agencies or individuals. <br /> <br />25 <br />
