General question in the 'don't know dept.' In the 'fly only' waters in Washington is/are you 'restricted' to an actual fly rod/line?

We have about a 4 month 'fly only' on the upper Rogue but you can use a spinning rod/float ... just no weight below the float (except for the fly's themselves).

More restrictive (to put it mildly) on the North Umpqua.
