Latest Update: 3/18/2026
Current Streamflow : 15 cfs @ Big T Above Lake Estes, 19 cfs @ Big T Below Lake Estes, 5 cfs @ Moraine Park
Lots of open water in the Estes region, Check the canyon section, and under Olympus Dam. Be on the lookout for some BWO action with the weather trending warmer and some added moisture in the air!
The flows are still in winter mode here. Small nymph rigs with BWO’s, Midges, or Sow Bugs are what we have been using lately. Emergers, like the Grey Foam Wing RS2, are producing right now. Stay in the 20-24 range for most bugs in this system. 5x tippet has been fooling fish as of late but if its a tougher day consider 6x.
Streamers have still been producing for us, think smaller patterns such as Buggers or a Sparkle Minnow.
The Big T has some awesome nymphing water. Check out our Euro Nymph Tying Class to get the pucks and boxes ready for the upcoming season.
Let us know if you have any questions or are looking for more info on fishing the Big Thompson.
