<br />4 Chapter 1.0 Purpose of and Need for Action <br /> <br />.' <br />i. . <br />~I" .,: <br /> <br />1.2.3 Colorado River Management Plan <br /> <br />One of the more important related federal actions is Grand Canyon National Park's <br />Colorado River Management Plan. The management plan will address resource <br />management and visitor experience along the Colorado River corridor in Grand Canyon <br />National Park within the framework of current NPS laws and directives. River use will <br />be regulated to ensure that the level and types of use are sustainable and that resource <br />impacts are within acceptable limits for long-term resource preservation. Scoping for <br />this plan began in August of 2002. Primary issues include allocation of river days to <br />private boaters and commercial river-running companies. The NPS will seek to <br />minimize the impacts of administrative use, which include river trips for research and <br />monitoring of resources of concern in the GCDAMP. <br /> <br />1.2.4 The Lake Mead Management Plan <br /> <br />The overall objectives of this lake management plan are to improve the management <br />of lakes Mead and Mohave to provide for the long-term protection of park resources <br />while allowing a range of recreational opportunities to support visitor needs. The draft <br />environmental impact statement was released in April 2002. It evaluates alternatives and <br />strategies, including the management of personal watercraft, for protecting the resources <br />and values of the Lake Mead National Recreation Area, while offering recreational <br />opportunities as provided in the park's enabling legislation, purpose, mission, and goals. <br />Species evaluated for impacts under this management plan that also are evaluated in the <br />Proposed Action below Glen Canyon Darn include the endangered razorback sucker <br />and southwestern willow flycatcher (SWWF). <br /> <br />1.2.5 Colorado River Recreation Management Plan, Glen <br />Canyon National Recreation Area <br /> <br />The last comprehensive management plan for this segment of the river was prepared <br />in 1984. Recent visitor contacts have revealed an increasing perception of conflict <br />between user groups. In addition, some visitors have reported concerns with crowding <br />and a diminished quality of experience. For these reasons, NPS has initiated a recreation <br />management planning process for the river that will address visitors' perceptions of <br />crowding, identify any resource conflicts, and evaluate the need for new management <br />strategies. <br /> <br />1.2.6 Personal Watercraft Rule-Making, Glen Canyon National <br />Recreation Area, Arizona and Utah <br /> <br />The purpose of and the need for taking this proposed action is to evaluate a range of <br />alternatives and strategies for the management of personal watercraft use at Glen <br />Canyon National Recreation Area. It is similar to the evaluation being conducted in the <br />
