Seaquest State Parks lies within the traditional territory of multiple Native American tribes including the Cowlitz Indian Tribe and the Yakama Nation.
In 1870, Charles John Seaquest, a Swedish emigrant arrived in the Silver Lake area. He was issued a patent for a 159-acre homestead within the boundaries of the modern-day park on January 15, 1876. Seaquest and his wife, Caroline had two sons, Alfred and Charles Jr. In 1905, Seaquest died of heart failure, and Caroline passed in 1914. After the death of his brother in 1938, Alfred willed the land to state for use as a park upon his own death, which occurred in 1945. In his will, Alfred stipulated that alcohol never be sold in the park. Seaquest State Park was established that same year.
Since its opening, the park has expanded to over 400 acres through acquisition of additional lands from the Department of Natural Resources and private citizens.
