<br /> <br />~, <br />N <br />~ <br />~. <br />00 <br /> <br />Annua'l Visitor Use Limits <br /> <br />To accompiish the objective of protecting the river <br />environment, maximum visitor use levels will be set. Use <br />levels will be measured in user days, where one uSer day <br />equals one person on the river for any portion of one <br />day. The total commercial and noncommercial use level <br />will be 150,076 user days for the summer season (May 1 <br />through September 30) and 19,874 user days for the <br />winter Season (October 1 to April 30). Future adjust" <br />ments to these levels may be made upon consideration of <br />information from the monitoring program relative to <br />impacts on beaches, attraction sites, cultural resources, <br />and the quality of the visitor experience. <br /> <br /> <br />As each trip leaves Lees Ferry, the number of commer- <br />cial passengers or noncommercial trip participants and <br />projected trip length will be recorded. With this <br />information, the user days for each trip will be <br />calculated. Each concessioner will receive a monthly <br />report of the number of user days utilized and will have <br />two weeks to report any needed adjustments due to <br />passengers who take partial trips. <br /> <br />Because of the tremendous demand for river trips it is <br />the goal of the N P5 to limit visitors to no more than one <br />trip during the calendar season, whether commercial or <br />noncommercial, unless they are traveling on the river in a <br />non recreational capacity (e.g., commercial crew or <br />owners, researchers, or park staff). Commercial boatmen <br />may participate in one private trip per year. <br /> <br />6 <br /> <br />.- <br />
