The region that became Wahkiakum County was home to the Wahkiakums, one of theChinookan peoples.[5]: 1 Archaeological investigation atSkamokawa indicated that the site, where the inhabitants engaged in fishing, hunting, wood-working, and tool manufacture, was approximately 2,300 years old.[5]: 15
Merchant sea captainRobert Gray, on hisColumbia River expedition in 1792, was the first European American known to arrive in the area. During salmon season in the early 1800s, theHudson's Bay Company's post atFort George operated a salting station in the region. In 1844, the first trading post was established in the area, near Skamokawa.[5]: 3 It was succeeded by Birnie's Retreat, a trading post established in 1846 byJames Birnie, who had previously worked for the Hudson's Bay Company. The influence of his wife, Charlotte Beaulieu Birnie, whose parents were a Frenchvoyageur and aKootenay tribe member, helped protectCathlamet during thePuget Sound War.[5]: 26–30
Wahkiakum County, with Cathlamet as the county seat, was created by the First Legislative Assembly of the Territory of Washington in 1854.[5]: 126
Early settlers came from Great Britain and the eastern United States until around 1870, when they were followed by a large number of immigrants from Sweden, Norway, Finland, andDalmatia. From 1870 to the early 1900s, there was a large population of Chinese residents who worked in the fish canneries.[5]: 34–36 The total population in 1912 was 5,283.[5]: 59 Lacking roads, travel between early communities was by foot or by boat.[5]: 98 Numerous areas of population disappeared in the years after roads began to replace water transportation.[5]: 92
Settlers engaged in fishing, logging, farming, and trading. Salmon canning began in 1866, quickly followed by the establishment of multiple canneries. In 1872, Chinese laborers were brought in to work in the canneries. Salmon canning over the years was impacted by overfishing and habitat degradation, with declines observed by 1889. The last salmon pack in Wahkiakum County took place in 1947.[5]: 75–82
As a densely wooded region, Wahkiakum County was an abundant source for logging companies. Logs were easily transported by water, although that transport relied on seasonal changes infreshets. When timber nearest the water had been felled, loggers had to rely on oxen, and then on railroads. The first logging train began operating in 1892, established bySimon Benson.[5]: 42–44
Many trees were also felled by immigrants to clear land for farming. By 1912, there were approximately 140 farms in the region, primarily dairy farms. The first cooperative creamery on the west coast was organized in 1898 in Skamokawa.[5]: 59 The first chapter in Wahkiakum County of theNational Grange of the Order of Patrons of Husbandry was organized in 1901.[5]: 67
The earliest periodicals in the area included theCathlamet Gazette (1889), theSkamokawa Eagle (1891) which continues to be the county's official newspaper, andthe Timberman (1899).[5]: 6–7
