Upper Klamath Lake is full of food for fish.
So it's a bit of a mystery why big fish like redband trout leave the lake and head into its tributaries, where there's less food.
Oregon Fish and Wildlife has a new tool in potentially solving the mystery: radio tags in the fish. The tags will help ODFW track fish movements in and around the lake.
ODFW biologist Bill Tinniswood expands our knowledge of the trout and the tracking devices.
