<br />02'''' <br />o 't.) 't <br /> <br />. <br /> <br />. <br /> <br />Glen Canvon Dam Adaptive Management Program <br /> <br />The Glen Canyon Dam Adaptive Management Work Group (AMWG) met in Phoenix, Arizona <br />on January 17-18,2002. The purpose of the meeting was for the federal advisory committee, the AMWG, <br />to approve and submit several recommendations to the Secretary of the Interior. These recommendations <br />largely focused on the Grand Canyon Monitoring and Research Center's (GCMRC) long-term strategic <br />plan, FY 2003 budget, and reports from several ad hoc groups of the AMWG, <br /> <br />At the meeting, there was substantial discussion of several important items, including the <br />following: (I) the geographic and statutory scope of the Glen Canyon Dam Adaptive Management <br />Program; (2) the status of the endangered humpback chub population in the Grand Canyon reach of the <br />mainstream Colorado River; (3) status of non-native fish control efforts in the mainstream; (4) status of <br />the sediment resources ofthe Glen, Marble, and Grand Canyon reaches of the mainstream Colorado River <br />under the EIS Record of Decision (ROD); and (5) receipt of two letters from various environmental <br />organizations stating that the Glen Canyon Adaptive Management Program may be failing to meet the <br />requirements of the EIS and ROD and associated USFWS biological opinion, Each of these major issues <br />is discussed below. <br /> <br />A source of continuing legal and administrative debate over the past several years in the AMWG <br />continues to be the legal and administrative mandate of the AMWG and the overall approach of the Glen <br />Canyon Adaptive Management Program (AMP), Much of this debate revolves around the funding of <br />major program elements of the AMP, as the primary source of funding is through the revenues generated <br />through the sale of hydroelectric power pursuant to the Colorado River Storage Project Act of 1956, <br />Currently, the Basin states' representatives and power customers believe that the Glen Canyon Dam EIS <br />and ROD, as well as the 1992 Grand Canyon Protection Act, clearly articulate the mandate and scope of <br />the AMP, This view is not sh<lJ"ed by other participants in the process, who believe that there are broader <br />authorities contained within other statutes, rules, regulations, and agency policies, Discussions regarding <br />the scop" of the AMP are likely to continue into the future. <br /> <br />Staff from the GCMRC made a presentation regarding the current biological status of the <br />endangered humpback chub in the Glen and Grand Canyon reaches of the mainstream Colorado River. <br />This species was one of the primary reasons for initiating the original EIS process, resulting in the 1992 <br />Grand Canyon Protection Act, final EIS and ROD, and associated ESA biological opinion. The biological <br />opinion called for the establishment of a second population of humpback chub in the Grand Canyon_ To <br />date, this has not been established, The GCMRC's presentation pointed out that the impact of the <br />non-native fish in this reach of the River have had significant effect on the survival of the humpback chub, <br />The non-native fish species of primary concern include rainbow and brown trout, red shiner, carp, striped <br />bass, and catfish, Consequently, the AMWG approved a recommendation to initiate an evaluation and <br />monitoring program to analyze potential non-native fish controls at Bright Angel Creek and the lower Little <br />Colorado River. The long-term recommendation from the AMWG was to evaluate an expansion of non- <br />native fish controls throughout the entire area of the AMP. Board staff urged the AMWG, GCMRC, <br />Reclamation, and National Park Service to consult with the Nevada Division of Wildlife and California <br />Department of Fish and Game prior to development of these activities, <br /> <br />II <br />
