Colorado Stream Update: Good fishing and a good amount of crowds

Current Conditions at San Juan:

The quality section of San Juan is fishing well. There is a good amount of pressure as we move into Fall. Small flies and light tippet is the name of the game. Patterns like bling midges, nightmare midges, and annelids have found some very nice trout lately. There are opportunities for the dry fly angler, however most eats remain subsurface. Remember that the Juan is a very technical tail-water. To find success, adjusting depth and tippet size can make a big difference.

The tail waters are fishing well with midge and micro mayfly patterns. Float fishing trips have been doing well. The river is flowing good and clear, float trips have been hooking lots of fish using nymph rigs and dry flies.  The fishing is great.  Clear skies and 60+ degree weather. The water temperature was between 56-59 degrees and Crystal Clear.
