Cathlamet Population. Mooney (1928) estimated 450 Cathlamet in 1780. In 1805-6 Lewis and Clark gave 300. In 1849 Lane reported 58. They are now extinct as a separate group.
Connection in which the Cathlamet have become noted. The capital of Wahkiakum County, Washington, perpetuates the name of the Cathlamet.
