DefIDe and specify ecology of native faunal components, especially threatened and <br />endangered species. <br /> <br />2. Determine, where possible, species' natural ranges (pre- and post-dam). <br /> <br />3. DefIDe food chain associations, interdependencies, requirements, etc., for native <br />species population targets. <br /> <br />4. Characterize historic and current expected use by species. <br /> <br />5. Characterize historic and current populations of Kanab Ambersnail and their <br />locations. <br /> <br />6. Determine range of natural variability/ecology and ecosystem requirements of wildlife <br />occupying the Canyon. <br /> <br />Socio-Economic Resources <br /> <br />I. Determine criteria that are important to or detract from wilderness experience. <br /> <br />2. Determine adequate beach quality, character and structure for camping throughout the <br />system. <br /> <br />3. Determine if operating criteria maintains safe and adequate power craft navigability in <br />Glen and Grand Canyons and upper Lake Mead. <br /> <br />4. Determine flow regimes necessary to maintain fish populations of 100,000 adult trout <br />(age class II plus). <br /> <br />5. DefIDe pattern of waterfowl and other wildlife use and conflicts to other uses. <br /> <br />Information needs were not specified for Lake Powell for FY 98. In FY 97, an <br /> <br />assessment was requested by the AMWG to defIDe Lake Powell water quality impacts related to <br /> <br />Glen Canyon Dam operations. The assessment revealed impacts from dam operations and <br /> <br />resulted in the AMWG proposing continuation of current monitoring programs in FY 98, until <br /> <br />new objectives and information needs could be specified for Lake Powell in FY 98. As noted, <br /> <br />Final Draft - (12/15/97) For AMWG Review <br />
