Lewiston
cityLewiston, Idaho, nestled in the north-central part of the state within Nez Perce County, serves as the county seat and a key city in the Lewiston, ID-WA Metropolitan Statistical Area. Positioned at the confluence of the Snake and Clearwater rivers, it holds the distinction of being Idaho's only seaport, thanks to dams and locks that enable some ocean-going vessels to reach its port. As of 2020, Lewiston had a population of 34,203, making it the third-largest city in northern Idaho. Lewiston's economy is diverse, with key industries including agriculture, paper and timber products, light manufacturing, and ammunition production. The city acts as a regional hub for transportation, retail, healthcare, and entertainment, supporting a market and trade area of approximately 180,000 people. Major employers include Clearwater Paper, Lewis-Clark State College, and the Lewiston Independent School District. Lewiston is notable for its historical significance, having been founded in 1861 following a gold rush and briefly serving as the first capital of the Idaho Territory in 1863. The city was named in honor of Meriwether Lewis of the Lewis and Clark Expedition, who camped near the site in 1805. Its unique position as Idaho's only seaport and its access to outdoor recreational opportunities, including the nearby Hells Canyon National Recreation Area, contribute to its distinctive character.
