Flow on the Big Thompson below Lake Estes is still rising and is at 600 cfs. Updated 6/16/2017. For these flows big flies on a dropper will work wonders; Pheasant tail, Prince nymph or Pat’s Rubber Legs will help get flies to the bottom in these flows. Follow with a copper ribbed RS-2 or a red Two Bit Hooker. Fat caddis nymphs are also getting attention. Hopper dropper season is here, so a Chubby Chernobyl with any of the above nymphs will work well. The inlet to Lake Estes is very low but still fishing well on sow bugs.
