placated in 1889 when the University of Idaho was awarded to nearby Moscow, north, and began instruction in 1892. Lewiston State Normal School, now Lewis-Clark State College, was established in 1893, as was another normal school or teacher education college, now defunct, in the south at Albion. These were the state's first three institutions of higher education. Lewiston was the site of the first public school in Idaho, in 1862. In December 1880, the district was the first to be chartered by the Legislature and thus carries the designation of Lewiston Independent School District #1. (Boise was second, opening school doors in 1865.) The City of Lewiston’s high reservoir failed on January 18, 2023. The failure caused flooding with the release of approximately three million gallons of water. Geography Lewiston is located at the confluence of the Snake and Clearwater rivers. Immediately west of Lewiston is the smaller twin city of Clarkston, Washington. The north-flowing Snake River departs Hells Canyon and forms the state boundary with Washington, while west-flowing Clearwater River defines the northern border of the city. At their confluence at the city's northwest corner, the lower Snake River turns west into Washington, and after passing four dams, empties into the Columbia River at Burbank. Lower Granite Dam northwest of the city is the Lower Granite Dam, the last and upper-most of the four dams on the lower Snake River, the largest tributary of the Columbia River. It was completed in 1975, and raised the river level back to Lewiston, effectively making it the eastern end of the new reservoir, Lower Granite Lake. Because of these dams (and their locks), Lewiston is navigable by some ocean-going vessels. At upstream of the Pacific Ocean (at the mouth of the Columbia River, adjacent to Astoria, Oregon), the Port of Lewiston has the distinction of being the most inland seaport east of the and Idaho's only seaport. Barges of timber products, grain, and other goods are shipped via the Snake-Columbia system to the Pacific. The first barge went to Portland; it was loaded with wheat and departed Lewiston on August 9, 1975. Levees Lewiston's main industries are agriculture, the paper and timber products from the mill owned and operated by the Clearwater Paper Corporation (until December 2008, a part of the Potlatch Corporation), and light manufacturing. Along much of the Snake River is a system of levees to protect against flooding; most
