Bonner's first sawmill, the Blackfoot Mill, was also known as the Bonner or Hammond Mill. It opened in 1898.[4] The Bonner Dam was built in 1908 by copper mining tycoon William A. Clark, to supply hydroelectricity to his sawmills in Bonner.

The Bonner Mill manufactured plywood. "On January 16, 1919, the 'greatest fire in the history of Western Montana' burned a large portion of the mill to the ground."[5] The mill was rebuilt and operational again by September, 1919. The Anaconda Company sold the mill to US Plywood-Champion Papers in 1972. It was sold to Stimson Lumber Company in 1993, and was closed in 2008.[6] In 2011, a heavy snowfall collapsed much of the mill's roof.[7]
