Current Conditions at Blue River Below Dillon:

The Blue in Silverthorne is fishing and has nice flows right now. However, we are seeing large crowds so use you best judgement when it comes to overcrowding. Small flies and tippet are the name of the game. Mysis, Beatis, and midges will be your go-to flies. Keep those flies smaller than a size 18 for best results.

The fishing is good.  Clear skies and 56-59 degree weather. The water temperature was between 52-55 degrees and Crystal Clear.
