I have never fished Sturgeon from the bank, but from my understanding they use those 10' - 12' rods so they can cast out a long ways into the big rivers. You may be fine with the 6' rod for the NW rivers, they aren't too wide.
I like to use 12-14 foot Rods for longer casting.
I've seen guys at Bonneville with 16 footers. It's a bit much, but
these guys are catchin fish. Also, if you have strong currents and a rocky bottom.
Pound a couple of nails into your lead, and make sure your dropper is lighter then your mainline.
Expect to loose a lot of lead.
I love fishing for those damn things.
