Doub1egun,
There are numerous outfitters that run jet boats on the Snake for cast and blast trips. There are some located in Lewiston, ID, Clarkston WA., Joseph OR. Asotin, WA. etc. If you goggle up "Snake River Cast and Blast" you should be able to find something that may suit you needs.

The length and cost of the trips vary from day trips up to a 5 day trip.

Steelhead fishing is dictated by the season. It usually opens in mid-Oct. for catch and keep about a month after the chukar season opens which is in mid-Sept. If steelhead isn't of importance, there is good trout, smallmouth, and sturgeon fishing. Sturgeon is catch and release only, but the possibility exists to catch a real monster!

Hope this helps some!
