Most anglers on the Willamette fish small Dick Nites, Flicker Spinners, etc. behind a hot & tot diver or similar. Hot & tots dive 10-14 feet.

It seems to me shad like to travel in the 10-16 foot water column, based on watching my depth finder. I'd rather fish slighly above them than below them. Find a good traveling lane on the inside bend of an island, anchor up and hang on.

Hope this info helps.
