Fishing Around Boulder In A Nutshell

Boulder Creek See Full Report

Flows throughout the canyon continue to be pretty low, but if you can find good holding water, you’ll find the fish. We seem to be having the most action on 6X tippet, and have even been going down to 7X on the blue bird days. There are still a few terrestrials hanging around, so you still have a few weeks left of using larger patterns like JC Specials and Chubby Chernobyl’s. As the weather continues to get colder, expect that option to drop off. As of now it seems like the fish are excited to get just one more big meal before winter! We’ve also been seeing more and more BWO on the water, which means we are truly into the heart of fall. As the weeks roll on, start downsizing your rigs and switching to small BWO patterns up top and either small and dark BWO nymphs or midge patterns dropped below.

Flows continue to be super low under Gross Reservoir, only 10 CFS. If you’re going to fish the Walker Ranch area, it’s not going to be hard to figure out where the fish are hanging. Look for the deeper pools and the fish will be stacked up. The hard part is trying to catch a few without turning off the whole hole. The best approach is to work your way up from the back of the hole to the head of the run, picking off fish and pulling them back towards the back of the hole, away from the other fish. We’re mainly seeing BWO activity, but Stonefly nymphs are still pulling fish as well. While skinny, don’t forget about some of the upper stretches of South Boulder Creek near Pinecliffe and Rollinsville as well. Another option is to do some exploring of the pocket-water above Gross Reservoir. It can be fantastic this time of year.

Clear Creek See Full Report

Clear Creek is currently living up to its name, with low, and clear flows and excellent fall fishing. You’ll find plenty of action with a dry dropper rig worked in the pocket water. Stonefly, Mayfly, Midge and Caddis imitations are all pulling fish. If you’re looking to work on your euro-nymphing skills, the canyon is the perfect place to find tumbling pocket water this time of year.

Big Thompson See Full Report

The Big Thompson below Olympus Dam is clear and low right now. Try a stonefly pattern up front with a small mayfly imitation like a RS2 behind. Try to stick to size 20 and smaller on your trailer for the best results. Another option would be to check out the upper stretches of the Big T in the Park and take in the show that the elk are currently putting on!

Blue River See Full Report

The Blue in Silverthorne continues to hold steady at 110 which is a great fall flow. In Silverthorne the typical Mysis and (black, grey and red) midge combo on 6x-7x is still your best bet, although eggs are working better every day. The fall BWO’s are getting pretty active now too, so bringing a small (#22) Two Bit Hooker into the mix is a great tactic as well.
