<br /> <br />c~~ <br /> <br /> <br />B. Wildlife <br /> <br />i.M <br />~. <br />~i.l <br /> <br />Representative animal life at beaches and attrac. <br />tion sites will be surveyed annually to determine if <br />any changes are occurring in species density or <br />diversity. <br /> <br />C. Water Quality <br /> <br />Water quality monitoring will include assessments <br />of any impacts river running might have on water <br />quality. The program will center around the pota- <br />bility of cooking and drinking water taken from <br />the Colorado River to dete,mine if any purifica- <br />tion beyond bleach is needed. It would also be <br />valuable to see if any ri ver runni ng activities are <br />impairing the water quality of the Colorado River <br />or sidestreams. Of particular interest is ,the <br />effect of visitor activities on sidestreams used for <br />drinking water or recreation., <br /> <br />D. Cultural Resources <br /> <br />Prehistoric Indian sites, petroglyphs and picto- <br />graphs, and historic sites in the canyon have <br />already been photographed from fi xed, permanent <br />points. Monitoring these sites will consist of <br />rephotographing the sites each year and analyzing <br />the photographs to determine the degree of <br />impact, if any. Visual observation and professional <br />documentation will provide additional informa- <br />tion. All monitoring, excavation, .and protection <br />will take place according to the Grand Canyon <br />National Park Cultural Resources, Management <br />Plan. <br /> <br />2. Visitor Experience <br /> <br />The quality of the visitor experi ence can obviously be <br />affected by the cleanliness of beaches and crowding <br />along the river corridor. The N PS will monitor visitor <br />perception of these potential problem areas. This will <br />be done by encouraging continued public involvement, <br />maintaining personal contact with river runners and <br />concessioners, and evaluating letters. <br /> <br />3. Commercial vs. Noncommercial Use Ratio <br /> <br />Studies will be done to assess public interest in <br />commercially guided trips compared to noncommercial <br />trips. The allocation of user days between these two <br />segments of the river running public will continue to <br />be an important management concern. <br /> <br />16 <br /> <br />~ <br />
