The Colorado River Indian Reservation was established by the Act of March 3, 1865, 13 Stat. 541, 559. Subsequently, its boundaries were modified by the Executive Orders of November 22, 1873, November 16, 1874, May 15, 1876, and November 22, 1915. The unallotted lands of the reservation are held by the United States in trust for the Colorado River Indian Tribes. Act of April 30, 1964, 78 Stat. 188. The Colorado River Indian Tribes have requested that the western boundary of the reservation be finally determined. Until such determination is made the leasing provisions of the Act of April 30, 1964, supra, do not extend to lands south of section 25, T. 2 S., R. 23 E., S.B.M., California. The Executive Order which describes the portion of the boundary considered in this memorandum is as follows: EXECUTIVE MANSION, May 15, 1876. Whereas an Executive Order was issued November 16, 1874, defining the limits of the Colorado River Indian Reservation, which purported to cover, but did not, all the lands theretofore set apart by act of Congress approved March 3, 1865, and Executive Order dated November 22, 1873; and whereas the order of November 16, 1874, did not revoke the order of November 22, 1873, it is hereby ordered that all lands withdrawn from sale by either of these orders are still set apart for Indian purposes; and the following are hereby declared to be the boundaries of the Colorado River Indian Reservation in Arizona and California, viz: Beginning at a point where La Paz Arroyo enters the Colorado River, 4 miles above Ehrenberg; thence easterly with said arroyo to a point south of the crest of La Paz Mountain; thence with said mountain crest in a northerly direction to the top of Black Mountain; thence in a northwesterly direction over the Colorado River to the top of Monument Peak, in the State of California; thence southwesterly in a straight line to the top of Riverside Mountain, California; thence in a direct line toward the place of beginning to the west bank of the Colorado River; thence down said west bank to a point opposite the place of beginning; thence to the place of beginning. |
