Washington Wildlife A-Z: R-River Lamprey Traditional Cache
Sootey: Looks like WDFW has made changes to this area and removed a beautiful piece of public land from public use unless you are boating. Too bad.

The River Lamprey is currently designated as a candidate species in Washington State. Federally it is classified as a species of concern. The main reason for the decline in population is from artificial barriers on their migration route like dams, decline in prey, chemical poisoning, being preyed upon by non-native species, poor water quality, and loss of habitat.
The status of the River Lamprey has been ignored for years, but The Army Corps of Engineers has funded studies to improve their passage at dam sites. Tribal and government agencies are working to improve conditions for the lamprey.
River lampreys are found from north of Juneau, Alaska south to the San Francisco Bay area. They are usually found in larger rivers like the Columbia, Fraser, Klamath, Eel and Sacramento, but can be found in other smaller rivers.
River Lampreys are a primitive type of fish and have been around about 240 million years. They resemble eels. They don't have jaws or paired fins. They have a sucker-like mouth. They don't have scales and have breathing holes instead of gills. Their average length is between seven and twelve inches. They have a typical life-span of six to seven years.
Both the males and females construct nests in the gravel on stream bottoms. The female lays between 11,400 to 37,300 eggs. The parents usually die after the eggs are layed and fertilized.
