The launch above the mouth of the toutle is called olequa.It is quite a long drift to the toutle but there is a lot of good pools along the way down.The take out is about 2 miles below the toutle,it's called camelot.I have done this float a few times and personal I don't think it's worth the hassel.This section of the cowlitz is best suited for sleds.You can park by the hiway and walk in to the mouth,it's a huge gravel bar.
