Big Thompson Report


I fished the Big-T today in the upper part of the canyon (1 to 2 miles downstream).  It was all dry fly action.  The flows at around 62 cfs dropped about 20 cfs from Saturday and early Sunday.  The water was a bit off color (probably the rain) but the fish didn't seem to mind and came up eagerly for the flies in every likely run.  One pattern, the XO, consistently drew the most strikes.  I use it a lot on South Boulder Creek.  Since it was already rigged up, I started with it.  I was using two dries - the XO (size 16) followed by a red quill parachute (size 18) 30-inches apart on a 10-foot leader with 6X tippet.

Turned out to be a pretty good day to go since it was a bit overcast and almost no fishermen.
