Completed in 1933, Rock Island Dam was the first dam on the Columbia River. It soared 40 feet high and included in its design a fish ladder to protect salmon and steelhead. In 1929, the Colville Tribe reported a harvest at Kettle Falls of 1,333 fish.
By 1934, however, that number had dropped to only 159. More recently, the Chelan County Public Utility District has combined its existing fish bypass system with habitat restoration and hatchery programs in an effort to revitalize fish populations in the Columbia. —JS
