Perrine proposed the diversion of the Snake River at Caldron Linn, a point approximately upstream of Shoshone Falls. Senator Clark and others who owned land at Shoshone Falls filed a lawsuit against the Twin Falls Land and Water Company, but were defeated in the Idaho Supreme Court in 1904. The Milner Dam and the major canals required to deliver water were completed by 1905. "On March 1, 1905, Frank Buhl gave a ceremonial pull on the wheel on a winch and the gates of Milner Dam were closed, and the gates to a thousand miles of canal and laterals were opened, and the Snake River was diverted, and that night Shoshone Falls went dry as the water rushed across the desert far above, and Perrine's vision was realized, and 262,000 acres of desert were shortly transformed."
