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 people. 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 home claims in the Place formerly inhabited by the Sammamish close present-day Bothell, and built homes. Eight families followed on culmination of the adjacent six years. In 1876, Canadian George Brackett bought estate and began personal ad logging out of a camp located upon the north bank of the Sammamish River in what is now the heart of downtown Bothell. A store, school, and sawmill followed more than the next several years.

In 1885, Brackett sold 80 acres (32 ha) to David Bothell, a settler from Pennsylvania. The town’s first postmaster, who bought his property from Bothell, named the town in his rave review when it was platted in 1888. Later that thesame year, a local railroad was built through the town to transport coal from Issaquah. Bothell was officially incorporated on April 14, 1909.

Bothell continued to amass as logging expanded and ship traffic brought increasing amounts of goods and passengers taking place and beside the river. As more people moved into the area, the Army Corps of Engineers approved to dredge and straighten the river in the years immediately after Bothell’s incorporation. Most ship traffic came to an abrupt grow less only a few years far ahead when Lake Washington was lowered in 1917. Water transport plus shifted to trucks after a brick road was built from Seattle. The logging economy declined speedily around the similar time, and the local economy shifted to farming.
