Clackamette, Dahl, and Meldrum parks offer a decent-good chance at getting into shad from the bank. Don't discredit the fishing dock further upstream on the Wets Linn side, it would be more cast and retrieve than back bouncing/plunking. Some of the other area parks on the West Linn side might offer some ok opportunity as well. Not sure how things are around the area as I have not been fishing there the past few days but bank and boat anglers alike were thinning out before the shad showed up. Best spots get taken early.
