<br />The endangered fish research flows, described in the Draft EIS, were <br />moved from the preferred alternative and addressed from a scientifically <br />based position within the Adaptive Management Program (AMP). This <br />modification has been made because Reclamation believes that the potential <br />effects of steady flows should be further studied before implementation to <br />evaluate uncertainties concerning the interactions between native and non- <br />native fish. Moving the endangered fish research flows to the AMP will allow <br />further investigations over the next two to three years to alleviate these <br />uncertainties. <br /> <br />Reclamation believes that these modifications are justified based upon <br />the comments received from the cooperators and the public, additional <br />information from meetings with researchers and other scientists and <br />reevaluations. <br /> <br />In addition, Reclamation will request, through the Federal appropriations <br />process, accelerated implementation of the selective withdrawal struc- <br />ture since temperature modification has been determined to be the most <br />critical factor affecting the recovery of endangered fish in Glen and Grand <br />Canyons. <br /> <br />The following table gives a detailed description of the parameters of the <br />preferred alternative in the Final EIS: <br /> <br />36 <br />
