Only once was I checked in regards to a "fly" in a flyfishing only fishery. It was on the Metolius and an office asked to see my HEAVILY WEIGHTED stonefly... which we use with a dropper system to drag the target fly down to the trout. You can't use split shot with a "fly" in Oregon so everyone who wants to catch trout on the Metolius with nymph patterns, ties patterns to work like split shot. Fact is, the primary technique for catching trout on the Metolius is using a dropper system dead-drifted with a weighted stonefly. Flyfishers say it is difficult to catch fish on the Metolius but they are normally dry fly anglers. The Metolius is not a dry fly river but a nymph river. If you want to catch two or three trout, use a dry fly. If you want to catch dozens, you use nymphs. The no split shot regulation is out of the stone age. It's a stupid regulation. We skirt the regulation with the heavily weighted stonefly patterns so split shot may as well be allowed. The officer evidently noticed the huge splash my pattern made when it hit the water so he wanted to look at my pattern. He looked at it and asked "is this a heavily weighted fly?" Duh. Yes it's a heavily weighted fly, that's why it splashes like it does when it hits the water. I said... "yup, that's what it is". He said okay and left. I think there must still be some elitist flyfishers in Oregon that continue to fight for the no split shot regulation and they are fools for doing so. It makes no difference if you're using split shot or a stonefly wrapped with three layers of lead wire for the underbody. You may as well be using split shot. Stupid rule.
