In Winters v. United States (1908), the Supreme Court held that the right to use waters flowing through or adjacent to the Fort Belknap Indian Reservation was reserved to American Indians by the treaty establishing the reservation. Although this treaty did not mention water rights, the Court ruled that the federal government, when it created the reservation, intended to deal fairly with American Indians by reserving for them the waters without which their lands would have been useless. （1.本文主题：印度安人使用水权问题；观点：最高法院认为，如果没有水权，印第安人的土地也无法发挥很大作用，因此水权归属于保留地印第安人—根据winters案件）
Later decisions, citing Winters, established that courts can find federal rights to reserve water for particular purposes if (1) the land in question lies within an enclave under exclusive federal jurisdiction, (2) the land has been formally withdrawn from federal public lands-i.e., withdrawn from the stock of federal lands available for private use under federal land use laws-and set aside or reserved, and (3) the circumstances reveal the government intended to reserve water as well as land when establishing the reservation.♦（特殊情况可使待裁决地区保留水权：a.待裁决地区位于联邦独家管辖区域的飞地 b.待裁决地区曾被联邦公共用地中分离—比如为了合法的私人用途，从联邦地区分离 c.政府建立保留地时特地保留水权和土地权）
Some American Indian tribes have also established water rights through the courts based on their traditional diversion and use of certain waters prior to the United States` acquisition of sovereignty. （2.由于历史原因，印第安部落在美国建国之前就开始使用一些水域，因此他们如今可获得此水权。）
For example, the Rio Grande pueblos already existed when the United States acquired sovereignty over New Mexico in 1848. Although they at that time became part of the United States, the pueblo lands never formally constituted a part of federal public lands; in any event, no treaty, statute, or executive order has ever designated or withdrawn the pueblos from public lands as American Indian reservations. （a.举RG的例子支持2.的阐述：RG地区在美国建立之前就存在，因此从来不是联邦公共用地。）This fact, however, has not barred application of the Winters doctrine. What constitutes an American Indian reservation is a question of practice, not of legal definition, and the pueblos have always been treated as reservations by the United States. （b.美国印第安属地的问题更多考量的是实际情况，而不是法律问题。）This pragmatic approach is buttressed by Arizona v. California (1963), wherein the Supreme Court indicated that the manner in which any type of federal reservation is created does not affect the application to it of the Winters doctrine. （c.另一Arizona案件也是支持上述说法。）Therefore, the reserved water rights of Pueblo Indians have priority over other citizens` water rights as of 1848, the year in which pueblos must be considered to have become reservations.（总结：因此，印第安部落水权优先于公民水权。）
