“The lack of utilization noted in the foregoing paragraph is serious enough from an industrial standpoint, but it is fraught with peculiar dangers in the case of the reservations where the water rights are subject to the operation of State law. On the Fort Hall Reservation (Idaho) beneficial use must be made of the water for the irrigable lands prior to the year 1916, in order to prevent the appropriation of the water by other water users; on the Wind River Reservation in Wyoming beneficial use must likewise be made before 1916; and on the Uintah Reservation (Utah) beneficial use must be made before 1919. The total investment in the construction of irrigation ditches and the purchase of water rights on these three reservations amounts to approximately $2,000,000, and in the case of the Wind River and Uintah Reservations the expenditure has been made from Indian funds. “Lack of proper utilization can not be charged to the indolence of the Indian. The present system is doubtless responsible for an undue lack of interest and indifference on his part. He has not been consulted in advance of the expenditure; the cost of the construction and the expense of maintenance on the basis of each acre irrigated have not been explained and brought home to him; the money being taken out of a tribal fund which has never become a part of his individual possession, he has not understood his intimate individual interest in its expenditure, nor has he realized the value, in dollars and cents, of the benefit. “In many cases irrigation on Indian reservations has been provided for in response to a perfectly natural and normal demand of white settlers, either for the opening to settlement of irrigable lands on Indian reservations or for obtaining water from streams flowing through Indian reservations for the irrigation of their lands on the outside. As a result, the construction of irrigation projects on Indian reservations has often preceded the proper preparation of the Indians for such construction and often has preceded the development of transportation facilities necessary to market the products of the land irrigated, and in the case of the large reservations in the Northwest irrigation has been brought to Indians unskilled in the art of irrigation, strangers to the art of agriculture, trained for generations to the exciting life of the chase, having no knowledge of any of the pursuits of modern civilized life except a somewhat general knowledge of the raising of cattle and horses. Generally, however, this premature development of irrigation has had sufficient justification in the necessity of such development to preserve the rights of the Indians to the water.
