Colorado Stream Update: Boulder Creek has been fishing really well and fishing should only continue to improve as flows increase. Look for the fish to be on aquatic worms, mayflies and midges.

Current Conditions at Boulder Creek:

Dry and dropper rigs have been producing. 7.5 foot leaders and 5x-6x tippet are the name of the game. A guide favorite right now is a Stimulator size 16 trailed by a bead head caddis or pheasant tail size 18. Good luck and have fun!

This is some of the best action of the year on Boulder Creek! The fish have not seen any pressure in months and good hatches of midges and blue winged olives keep the fish rising. The midge hatch is on fire on the local creeks! Our professional fly fishing guides recommend fishing a big dry fly you can see such as a Parachute Adams, for best results tie on a Brook’s Sprout Midge a foot behind your Adams. As the weather warms the water is rising as well. Runoff is around the corner so hit your local streams around Denver/Boulder while you can! We are catching with a dry dropper combo! Midges seem to be the name of the game, small and red patterns like the Rojo Midge or Zebra Midge have been hooking their fair share of trout.  The fishing is good.  Clear skies and 60+ degree weather. The water temperature was between 36-39 degrees and Slightly Off.
