The Confederated Tribes of Coos, Lower Umpqua and Siuslaw has a language program to revitalize them.

William Clark, wintering at Fort Clatsop near the Columbia with Meriwether Lewis and the Corp of Discovery, reported the existence of the "Cook-koo-oose nation".

His journal entry stated: "I saw several prisoners from this nation with the Clatsops and Kilamox, they are much fairer than the common Indians of this quarter, and do not flatten their heads."

In 1876, the sub-agency was handed over to white settlement and the Indians were assigned to relocate to the Siletz Reservation, which created a major disruption among the tribal members.

In subsequent years, they began providing food assistance for low-income families and established job placement and drug and alcohol abuse programs.
