(Klamath Falls, OR) -- After the removal of four dams in the Klamath River, salmon are returning much faster than biologists expected. Two dams remain on the river and salmon have passed fish ladders at the Keno and Link River dams. They've reached the Sprague River. Biologists say the salmon are advancing faster than their tracking program was set to record. They're having to expand the cameras and other monitors on an almost daily basis.
