Do you think the Oregon regs prohibit sinking tip "lines" on the N. Umpqua? To me it reads no added weights (i.e. lead shot) to the line.
The fly only water on the North Umpqua is one place you WANT to really read the regulations. Similar may be in place somewhere else in the State, but I've yet to find it.
The use of sinking lines (tips, line, heads, etc.) is a fairly recent change (well, a few years back). Up to that time it was floating lines and unweighted flies only. By 'unweighted' I mean not even
a wire rib or a bead head.
Again, a 'dated' conversation with the F and G folks up in Salem, but asked (for the North Umpqua) 'what constitutes 'added weight?' Lead wire, bead heads were a given, but what about just normal fly tying 'stuff' such as tinsel, etc. Answer was 'flat tinsel' would be 'ok,' but 'oval' would be considered 'added weight.'
Another 'dated conversation' with with OF&G was why the change to you can use a sinking line (etc.)? Darned interesting conversation. Apparently some of the more 'inventive' locals read the Regs and said .... "Hummmmm?"
What they did was to take a HUGE salt water (we're talking Shark size here Boys and Girls) hook, cut it off at the bend, tie fly on to that with a trailer/stinger hook. Very legal per the regs ... and the thing would sink like a rock. "Camp Water" just above/below Steamboat was their fav. place to play the game.
Gather there were more than one 'confrontation,' tickets and/or arrests ... one of which ended up in front of a Judge. End game was there was no bar (bad pun intended) against using an 'articulated fly.' The trailer hook met all the posted requirements for gap size/what-ever.
