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.  As the weather continues to get warmer, expect more action from BWO’s and some early caddis. Flowers are already starting to blom which means we are getting closer and closer to Spring.  As we continue to move toward Spring start 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 11 CFS t. 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 entire 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.

Clear Creek canyon is open. Midges are still going to be one of the best flies to use.  However, especially on cloudy days, look for Blue Winged Olives to start hatching.  They should start appearing any day. The best fishing with blue winged olives will be on cloudy days.  Be prepared to hit the water when the weather goes south!

Big Thompson See Full Report

The Big Thompson below Olympus Dam is clear and low right now. Try small pheasant tail pattern up front with a small midge imitation like an RS-2, Top Secret midge or Blue Poison Tung behind. Stick to size 20 and smaller on your trailer for the best results.

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.
