Latest Update: 8/14/2026
Current Streamflow : 62 cfs @ Big T Above Lake Estes, 60 cfs @ Big T Below Lake Estes, 23 cfs @ Moraine Park
The Big Thompson has seen its flows start to creep down a bit, which means that the small bugs have started to come back out and fish will be looking up for dries rather than nymphs fished subsurface.
Caddis, PMD and BWO patterns have been productive whether they are fished as dries or nymphs. This time of year fish start to focus on terrestrials as a primary source of food as well. Which means that fishing an ant or beetle pattern with a small dry trailing it has been a great rig. A hopper dropper with some kind of terrestrial and a small PMD or Caddis dropper has also been a great choice.
Summer heat is in full swing meaning that keeping an eye on water temperatures especially in areas below Drake is a good practice. For some tips and good practices to keep fish safe during the hottest parts of the year click here.
