will be located within the boundaries of the Hualapai Indian Reservation. It is estimated that approximately 20,132 acres of Hualapai Indian Reservation land would be required for rights-of-way. National park encroachment--Storage of water in the reservoir to its normal water-surface elevation 1866 would raise the water surface through the Grand Canyon National Monument for a distance of 39 miles, approximately 13 miles of which would border on the Grand Canyon National Park along the common boundary upstream from the mouth of Havasu Canyon. At the lower or western end of the park, near the mouth of Havasu Canyon, the water surface would be raised about 89 feet above natural conditions at normal riverflow. In the event of infrequent flood conditions, the surface of the river would be somewhat higher for periods of short duration. This depth would gradually lessen going upstream from Havasu Canyon until the effect would become imperceptible at about 17 miles under all conditions of the riverflow. Havasu Canyon encroachment--The Bridge Canyon Reservoir would inundate the present mouth and the extreme lower end of the canyon bottom of Havasu Creek. This would provide a comparatively easy access route into this scenic area while detracting but very little, if any, from its natural beauty. With an easy route available, more tourists would visit the canyon than at present, resulting in an excellent opportunity for the Havasupai Indians to increase their income from their established tourist enterprise. Exchange lands--The Indian lands required for rights-of-way for Bridge Canyon Dam and Reservoir are tribal lands held in trust 23Epson Perfection 4870 Photo, 400 dpi, 8 bit, 14,411,776 byte
