You are going to be predominantly in a trout/steelhead area. There are plenty of bass and walleye too(experts say the Columbia is going to yield the next world record) and there is pike in long lake(five minute drive from Spokane). The crappie fishing is mostly unknown to me south of Spokane, but to the north there is Loon and Deer lake. The average is around 8-9", with a few fish up to 14". Don't expect anything like the crappie fishing down south, but it can still be pretty darn good. I live 45mi north of Spokane, so I might be able to point you in the right direction, or at least find someone who can. If you are willing to try the trout fishing, you are in for a great time, in Loon lake they get up to 25lbs.
