Colorado Stream Update: The best fly fishing on the Big Thompson is directly below Lake Estes and down river about three miles from the dam.

Current Conditions at Big Thompson:

The baetis insect-- this is the famed Blue Wing Olive-- is in full swing on the Big T right now! We aren't quite seeing a lot of surface feeding just yet, but these hungry trout are definitely feeding on baetis nymphs and emergers sub-surface. Size #20 Pheasant Tails are a great baetis nymph pattern and size #22 gray RSIIs are working very well imitating the emerging stage of their life cycle. The water is still very skinny so this is the place to break out the 6x tippet spool.

The fishing is good.  Clear skies and 48-51 degree weather. The water temperature was between 40-43 degrees and Crystal Clear.
