I'm not sure where your talking about, but if it's on the Spokane River, I think you need a permit from the Spokane Tribe and I believe there are Smallmouth, Walleyes, Rainbows and maybe an errant Silver or two. I'm not too sure though, as I've only been there once. You might call the Spokane Tribal Headquarters and ask.
Sorry, that's the best I can do.
