Use of the name "Onalaska" in the United States
The name for the community comes from the poem "The Pleasures of Hope" by Scottish poet Thomas Campbell. Onalaska, Washington, Onalaska, Wisconsin, Onalaska, Arkansas and Onalaska, Texas are all historically connected to one another through the lumber industry.
Onalaska is in west-central Lewis County, in the valley of the South Fork of the Newaukum River. State Route 508 passes through the community, leading west 9 miles (14 km) to Napavine and east 24 miles (39 km) to Morton. Chehalis, the Lewis county seat, is 14 miles (23 km) northwest of Onalaska.
According to the U.S. Census Bureau, the Onalaska CDP has an area of 1.6 square miles (4.2 km2), all of it recorded as land. The South Fork of the Newaukum forms the southern edge of the community, and Carlisle Lake is on the western edge. The Newaukum River flows west to the Chehalis River at Chehalis.
Onalaska was built around the inland mill established by the Carlisle Lumber Company in 1909. At its peak in 1929, company inventory numbered over 20 million board feet of lumber — enough to stretch all the way to the Panama Canal.
The company's surviving 225-foot smokestack near Carlisle Lake was built approximately in 1920, and is the last trace of one of the most successful mid-sized sawmills in Washington state. In May 2021, the site was listed to the Washington Heritage Register by the Washington State Advisory Council on Historic Preservation.
The mill employed a sizeable number of Japanese and Japanese Americans. They lived north of today's State Route 508 and east of Carlisle Avenue. The streets, which ran parallel to Carlisle Avenue were called Oriental Avenue, Nippon Avenue and Tokyo Avenue.
According to Onalaska, a history of the Carlisle Lumber Company by Vic Kucera, the 1940 census showed 62 people of Japanese descent living in Lewis County. Because of their experience in the mill, the local Japanese Americans were forced to relocate to Camp Tulelake in California to help with its construction, Kucera writes. The Army relied on their labor to finish the camp where they were subsequently interned for the duration of WWII.
