Fishing Around Boulder In A Nutshell

Boulder Creek See Full Report

Flows throughout the canyon are pretty skinny, but so far fishing has remained fantastic, and should continue to stay that way as we get deeper into fall. The sections from Boulder Falls up past Roger’s Park and Castle Rock up to Nederland are pretty much at their minimum level, so your best water is going to be from Boulder Falls down through town. This is the time of year when you can use just about the entire selection in your fly box and find fish. Caddis, Terrestrials, Mayflies, Stones and midges are all on the menu right now. One of our most successful rigs right now is a dry dropper combo using a large attractor dry fly up top with just about any flashy nymph below. Try a pat’s rubber legs, jigged hare’s ear, green drake nymphs and small rainbow warriors for consistent success. The area around the library and justice center always hold some nice fish, and if you haven’t checked out some of the great pocket water within the first mile below 4 mile creek in the canyon, now is the time to take a look!

Flows were unfortunately cut under Gross Reservoir on the 17th to 12 CFS, which is extremely low. 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. Caddis, small stones and mayflies are the main food source. A dry dropper rig can make for a very fun afternoon or evening, Don’t forget about some of the upper stretches of South Boulder Creek near Pinecliffe and Rollinsville as well. Take a drive and take in the fall colors and stop for some great low flow fishing. Another option is to do some exploring of the pocket-water above Gross Reservoir.

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 continues its downward trend and is at a great late summer flow. In Silverthorne the typical Mysis and (black, grey and red) midge combo on 6x is still your best bet. Outside of town work larger attractor nymphs such as stonefly and caddis patterns mixed with smaller PMD patterns. With the lower water a terrestrial patterns worked along the edges will also get attention. The lower blue has been fishing well with green drake and PMD nymphs. The Drake dry fly bite seems to have waned, but has been replaced by a solid PMD dry bite.
