Imhaha was a stern-wheel steamboat which operated on the Snake River in the Pacific Northwest in 1903. The steamer was built, launched, placed in service, and wrecked within a single year. The rapids on the Snake river had only rarely been surmounted by a steamboat, and generally only with the aid of a steel cable for lining used to winch the entire boat upstream through the rapids. After only a few trips, Imnaha was destroyed in Mountain Sheep rapids, just downstream from the mining settlement of Eureka, on the Oregon side of the river.
