We arrived at Roaring River mid-afternoon on Sunday of the opening weekend for the catch-n-release season. Not quite knowing what to expect, we were pleasantly surprised to find 5-6 rainbows in the first pool that were in the 3-5 pound range. I had on trout crack, from the prior river we were fishing and decided to go with it. A couple of casts into the pool and I was hooked up…. With a sculpin. Not exactly what we were looking for. I landed a couple of smaller rainbows before decided to switch over to a brown San Juan worm. I spotted a nice rainbow if the tail-end of the pool and within a couple of casts it aggressively came over and took the fly. After a short fight I brought the fish in, a nice male in the 20-21 inch range. Rob and I proceeded to catch fish after fish out the pool, all big rainbows in the 20-22 inch range. The fish behaved like hatchery fish, aggressively taking our flies like they were hatchery pellets. There were even a couple of times they even attempted to eat the green split-shot on our line. We continued to work our way downriver, catching one or two good fish in every pool. I did manage one pretty nice rainbow further downstream in the 23-24 inch range. We searched the all of the pools in the upper river for some of the larger fish we had heard about, but were unable to locate anything larger than 5-6 pounds. We checked out the normal catch-n-release section of river, which didn’t seem to hold as many or as large of fish, but there were a couple pairs of rainbows actively spawning. The last place we checked out was down by the highway bridge, as I knew this was one of the prime big fish spots. There were a couple of smaller rainbows around, but nothing to get real excited about. The river was pretty low, so you could see all the way to the bottom of the pool. We headed back upriver and caught a couple more fish before the siren finally rang at 4:00, ending our day.
