Chetlo Harbor, also known as over the years as Cougar Bend, Napoleon, and Stanley, was a small settlement located near the southwest coast of Washington State, in the southeast corner of Willapa Bay at the mouth of the Naselle River.

Chetlo, or Jetlo, is a Chinook Jargon word meaning oyster.

[citation needed] The people were served by a boat out of South Bend once a week, bringing the mail, freight, and passengers, if any.

[citation needed] The lack of transport was why there were one-room schools all up and down the river, some only a couple of miles apart.

All the log towing was done by tugs, and there was quite a fleet of them; the Flora Brown, Agnes, Launel, Myrtle, Queen, and the Defender.

[4] A town was platted a mile or two below the present highway bridge on the west side of the river and above the old Sunshine Mill.
