Colorado Stream Update: Boulder Creek is looking good in beautiful Boulder, CO! Now is a great time to hit the town stretches of the creek or take a drive up into Boulder Canyon!

Current Conditions at Boulder Creek:

If you like lots of dry fly action and wild brown trout then Boulder Creek is your place to be! Now is a good time for prospecting with a dry dropper rig or fishing the deeper holes and slots with a tandem nymph rig.

Boulder Creek is ice free and the fly fishing is great This is some of the best action of the year on South 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. 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 water is high everywhere around Colorado’s Front Range. To find good fishing try hiking to mountain streams and lakes. Many of these streams are flowing at a fishable level. Use a double indicator rig. Keep your indicators in the same line and this will help promote a good drag free drift. Make sure your nymph rig is deep enough, find the bottom of the river and fish up.  The fishing is good.  Clear skies and 60+ degree weather. The water temperature was between 36-39 degrees and Slightly Off.
