Excerpt from Geology and Water Resources of the Gila and San Carlos Valleys in the San Carlos Indian Reservation, Arizona In recent years the Indian farmers in the valleys Of Gila and San Carlos rivers, in the San Carlos Indian Reservation (pl. I and fig. Have been seriously handicapped by an inadequate supply of water for irrigating their crops. A shortage Of water at times when it is most needed has tended to discourage those Indians who are making an earnest effort to farm and has done much toward neu tralizing the efforts Of the reservation Officials to interest others in agriculture. The water shortage has been due to a lack Of water in the streams at certain times of the year and to the difficulties of keeping diversion dams and ditches in operation on account _of wash outs caused by Sudden floods in the rivers and by torrents in the tributary arroyos during heavy rains. In the river valleys many tracts Of good land now lying idle could be made productive if sufficient water were obtainable. An extension of the present system to include these lands, however, would be likely to fail, from the same causes that contribute to the inadequacy Of the present system.
