My dad, Aric, and I went out on the Rush from about 9:00 to noon on Sunday. We spent the entire outing nymphing, although we saw a few trout rising to emerging midges. We ran standard nymphs — pheasant tails, hare’s ears, and princes — with size 18 or 20 black zebra midges below, and caught almost all our 20-ish combined fish on the nymphs. The action was definitely faster earlier in the morning and started slowing down as the air got warmer, increasing the snow melt and cooling the water. Until all the snow melts off make sure to get out early before the stream temps begin to fall. You can definitely catch fish all day, but the best action will be earlier!
