Show I. INTRODUCTION I. A. Purpose of the Plan Glen Canyon National Recreation Area ( NRA) in Utah and Arizona ( Fig. 1) was established as a unit of the National Park Service by Public Law 92- 593 on October 27, 1972 ". . . to provide for public outdoor recreation use and enjoyment of Lake Powell and lands adjacent . . . and to preserve scenic, scientific, and historic features contributing to public enjoyment of the area. ..." Among the natural resources essential to public use and enjoyment of the recreation area are the waters of 163,000- acre Lake Powell, its five major tributaries, and the waters of adjoining lands, including springs, seeps, ephemeral streams, and ground water.
