I agree with all of the above. I catch plenty on the same stuff I use at strawberry, Jordanelle and other waters. Be ready to change up a bit and try different depths to find them. Silver scale sling blade or luhr Jensen 6” range dodger or similar and pink squid tipped with Berkley maggots trolled at 1.5 to 1.7 mph is a pretty solid starting point. If you catch them at the berry with the gear you have you should be able to catch them at the Gorge. Need to find them first of course.
Good luck
