Latest Update: 7/3/2026
Current Streamflow : 120 cfs @ Big T Above Lake Estes, 122 cfs @ Big T Below Lake Estes, 59 cfs @ Moraine Park
The Big Thompson has had its flows holding steady both above and below Lake Estes which has meant that the fishing has been great lately. The steady flows have caused the bug life to become increasingly more active with a number of different bug species hatching consistently.
PMDs, Caddis and Yellow Sallies have been the most active, fishing these both as lone dries or in a dry dropper rig has been a great way to go. The bugs have been primarily hatching in the early morning or late afternoon into the evening with single Caddis dries fishing particularly well in the evening. Streamers can also be a safe bet in slower moving holes and near structure.
