Try squirmy worms in hot pink size 16, chenille and San Juan worms in pink can work as well. Zebra, poison tung, juju midge, pheasant tail patterns are working as well. Chubby Chernobyl with a midge dropper beneath has worked well in the slower water along the banks. Dries try Parachute Adams, ext. body BWOs Griffiths Gnat, mole flies.

Updated 6/5/23 The flows into Lake Estes are currently 831 cfs. As of this post current flows out of Lake Estes are now running at 264 cfs. Water temp below the dam was 48 degrees. Fishing continues to be very good from the spillway on down into the canyon. With the current rains up in the park the lower flows out of Olympus dam may not last for to long. Patts Rubber leg, squirmy worms in pink and purple size 16, stone flies, egg patterns, Mighty mite baetis, Sparkle wing RS2 in Black and Gray in sizes 18/20 work well and Copper ribbed and Foam Head emergers size 18,20,22 in blk, grey and brown have been working well. Pheasant tails Blue poison tung and zebra midges size16,18,20 work well. Hot head sow bugs have been working well. Dry flies to use during a hatch would be small extended body BWOs parachute Adams, purple haze parachute flies in sizes 14 all the way down to size 26 have been productive. Griffiths gnat trailed behind the parachutes have worked well when the trout are rising to the surface. Wooly Buggers try Thin Mints, olive and black and black leech patterns are still working well along the banks in the tail water deeper pools.

Spring is here on the Big Thompson and with it came our annual run off. The larger bugs in our boxes have started to produce such as stoneflies, worms, scuds, and sowbugs. We are also starting to see some terrestrials, so now is a good time to start fishing bigger chubby chernobyls. The flows are pretty high now, but when they come back down smaller bug patterns such a #18-20 Micro Mayfly, or a #18-20 Poison Tung will be effective. Fishing a #20 UV Emerger, an #18-20 Sparkle Wing Rs2 or #18-22 Copper Rib Rs2 are great flies to fish the middle of the water column or behind an adult dry fly to target fish looking for emerging insects. We really like Sprout Midges #18-24, and The Eric's Hi-Vis Midge #20-24 for the fish eating midge adults and cripples. For fishing to rising fish we like to use the Extended body Bwo #18-22 and the CDC Baetis dun #18-22. Dry fly eats can be delicate, and often times are hard to detect with such a small fly. Having tools such as BioStrike or running a double dry fly rig can help you keep track of your dry flies on the surface so you don't miss a hook-set. Let us know if you have any questions or looking for more info!

Spring is here on the Big Thompson and with it came our annual run off. The larger bugs in our boxes have started to produce such as stoneflies, worms, scuds, and sowbugs. Make sure you still have smaller bug patterns such a #18-20 Micro Mayfly, or a #18-20 Poison Tung, as these are great patterns that will continuously produce on the Thompson. Fishing a #20 UV Emerger, an #18-20 Sparkle Wing Rs2 or #18-22 Copper Rib Rs2 are great flies to fish the middle of the water column or behind an adult dry fly to target fish looking for emerging insects.
