The lamprey, a kind of jawless fish related to an eel, has been a central part of the lives of American Indian tribes that lived in the Northwest United States. Every year in June, Native American tribespeople take part in the tradition of intercepting Pacific lamprey as they make their way upstream at Williamette Falls in Oregon. Some researchers say that the increasing presence of large dams in the area may have contributed to the disappearance of the Indians' food source.

As long as Indians have lived in the Northwest, they have looked to lamprey for food. But in the decades since dozens of hydroelectric dams have harnessed the power of the Columbia, Willamette and Snake rivers to make electricity, this jawless fish popularly known as an eel has steadily declined until Columbia Basin tribes have just a few places left to go for lamprey.

The lamprey, a jawless fish popularly known as an eel, has steadily declined until Columbia Basin tribes have just a few places left to go for lamprey. Their name comes from a mixture of Latin and Greek which translates roughly to "stone-lickers". Lampreys, which have a toothed, funnel-like mouth adapted for sucking, have no scales (in that way they are similar to eels). Their skeletons are made of cartilage, not bone. They are found in both coastal and fresh waters.
