CONDITIONS.

SEC. 2005. CONDITIONS. (a) The Lake Andes-Wagner Unit shall be constructed, operated and maintained to irrigate not more than approximately 45,000 acres substantially as provided in the Lake Andes-Wagner Unit Planning Report—Final Environmental Impact Statement filed September 17, 1985, supplemented as provided in section 2003 of this title. The Lake Andes-Wagner Unit shall include on-farm pumps, irrigation sprinkler systems, and other on-farm facilities necessary for the irrigation of not to exceed approximately 1,700 acres of Indian-owned lands. The use of electric power and energy 106 STAT. 4681 required to operate the facilities for the irrigation of such Indian-owned lands and to provide pressurization for such Indian-owned lands shall be considered to be a project use. (b) The Marty II Unit shall include a river pump, irrigation distribution system, booster pumps, irrigation sprinkler systems, farm and project drains, electrical distribution facilities, and the pressurization to irrigate not more than approximately three thou-sand acres of Indian-owned land in the Yankton-Sioux Indian Reservation, substantially as provided in the final report for the Marty II Unit prepared pursuant to section 2003 of this title. (c) The construction costs of the Lake Andes-Wagner Unit allocated to irrigation of non-Indian owned lands (both those assigned for return by the water users and those assigned for return from power revenues of the Pick-Sloan Missouri Basin Program) shall be repaid no later than forty years following a determination by the Secretary that the project is substantially complete. Repayment of the construction costs of the Lake Andes-Wagner Unit apportioned to serving Indian-owned lands and of the Marty II Unit allocated to irrigation shall be governed by the Act of July 1, 1932 (47 Stat. 564, Chapter 369; 25 U.S.C. 386a). (d) Indian-owned lands, or interests therein, required for the Lake Andes-Wagner Unit or the Marty II Unit may, as an alter-native to their acquisition pursuant to existing authority under the Federal reclamation laws, be acquired by exchange for land or interests therein of equal or greater value which are owned by the United States and administered by the Secretary or which may be acquired for that purpose by the Secretary. (e) For purposes of participation of lands in the Lake Andes-Wagner Unit and the Marty II Unit in programs covered by title V of the Agriculture Act of 1949 (7 U.S.C. 1461, et seq.) as amended by subtitle A of title XI of the Food, Agriculture, Conservation and Trade Act of 1990 the crop acreage base determined under title V of that Act as so amended and the program payment yield determined under title V of that Act as so amended shall be the crop acreage base and program payment yield established for the crop year immediately preceding the crop year in which the development period for each Unit is initiated. For any successor programs established for crop years subsequent to 1995, the acreage and yield on which any program payments are based shall be determined without taking into consideration any increase in acreage or yield resulting from the construction and operation of the Units. (f) Mitigation of fish and wildlife losses incurred as a result of the construction and operation of the facilities authorized by this section shall be concurrent with the construction of the Unit involved and shall be on an acre-for-acre basis, based on ecological equivalency. In addition to the fish and wildlife enhancement to be provided by the fish rearing pond of the Lake Andes Unit, other facilities of that Unit may be utilized to provide fish and wildlife benefits beyond the mitigation required to the extent that such benefits may be provided without increasing costs of construction, operation, maintenance or replacement allocable to irrigation or impairing the efficiency of that Unit for irrigation purposes.
