Bothell (pronounced /bɒθəl/ both-əl) is a city located in King and Snohomish Counties in the state of Washington. It is part of the Seattle metropolitan area. The population was 33,505 as of the 2010 census. Prior to annexation and the 2000 census, the northern portions of Bothell which lie in Snohomish County were considered a part of the Alderwood Manor-Bothell North census-designated place.
Prior to European settlement, the Sammamish River Valley from Lake Washington to Issaquah Creek south and upstream of Lake Sammamish was inhabited by a population of as many as 200 native Americans known as the Sammamish. The Sammamish were relocated after the Puget Sound War in 1856 to reservations and non-reservation lands.
In 1870, Columbus S. Greenleaf and George R. Wilson filed land claims in the area abandoned by the Sammamish near present-day Bothell, and built homes. Eight families followed over the next six years. In 1876, Canadian George Brackett bought land and began commercial logging out of a camp located on the north bank of the Sammamish River in what is now the heart of downtown Bothell. A store, school, and sawmill followed over the next several years.
