SEC. 2. FINDINGS.

    Congress finds as follows:
            (1) Congress approved the Pick-Sloan Missouri River Basin 
        Program by passing the Act of December 22, 1944 (commonly known 
        as the ``Flood Control Act of 1944'') (33 U.S.C. 701-1 et 
        seq.)--
                    (A) to promote the economic development of the 
                United States;
                    (B) to provide for irrigation in regions north of 
                Sioux City, Iowa;
                    (C) to protect urban and rural areas from 
                devastating floods of the Missouri River; and
                    (D) for other purposes.
            (2) The Angostura Unit--
                    (A) is a component of the Pick-Sloan program; and
                    (B) provides for--
                            (i) irrigation of approximately 12,218 
                        acres of productive farm land in South Dakota; 
                        and
                            (ii) substantial recreation and fish and 
                        wildlife benefits.
            (3) The Commissioner of Reclamation has determined that--
                    (A) the national economic development benefits from 
                irrigation at the Angostura Unit total approximately 
                $3,410,000 annually; and
                    (B) the national economic development benefits of 
                recreation at Angostura Reservoir total approximately 
                $7,100,000 annually.
            (4) The Angostura Unit impounds the Cheyenne River 20 miles 
        upstream of the Pine Ridge Indian Reservation in South Dakota.
            (5) The Reservation experiences extremely high rates of 
        unemployment and poverty.
            (6) There is a need for economic development on the 
        Reservation.
            (7) The national economic development benefits of the 
        Angostura Unit do not extend to the Reservation.
            (8) The Angostura Unit may be associated with negative 
        effects on water quality and riparian vegetation in the 
        Cheyenne River on the Reservation.
            (9) Modernization of the irrigation facilities at the 
        Angostura Unit would--
                    (A) enhance the national economic development 
                benefits of the Angostura Unit; and
                    (B) result in improved water efficiency and 
                environmental restoration benefits on the Reservation.
            (10) The establishment of a trust fund for the Oglala Sioux 
        tribe would--
                    (A) produce economic development benefits for the 
                Reservation comparable to the benefits produced at the 
                Angostura Unit; and
                    (B) provide resources that are necessary for 
                restoration of the Cheyenne River corridor on the 
                Reservation.
