Colorado Stream Update: Flows on Boulder Creek are running high! But anglers can still find solitude, clear-ish water and good fishing above Boulder falls....

Current Conditions at Boulder Creek:

Attractor dries with bead head droppers have been fooling wary fish in the slowest seams, pockets and eddies. 7.5 foot leaders 3x-5x tippet.

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. The water is high but we are still catching fish. Be persistent. The fish are still there! Fishing is decent close to Boulder. Use a double indicator rig. Keep your indicators in the same line and this will help promote a good drag free drift. The water is fast and deep better bring your split shot! Make sure your nymph rig is deep enough, find the bottom of the river and fish up. Be careful out there the water is running high and fast. Make sure you are fishing with a good landing net; the fast current can make it difficult to land fish. Working streamers has been very productive! Try using a big fly like a Sex Dungeon or Sculpzilla trailed by a Kolanda Mini Sculpin or Belly Ache Minnow. Virtually every major stream is running high. For better flows try hitting the Big Thompson just outside of Estes Park. Standard nymph rigs have been producing fish. The fishing is good but you better watch out for tubers, rafters, and kayakers! Most streams are high and dirty, but aggressive brown trout are still taking micro streamers. Try fishing Kolanda’s Mini Sculpin in black! Our local creeks provide the dry fly angler with amplitude of opportunity close to Denver and Boulder! Now is some of the best fishing of the year! All you need is a big attractor dry fly and a bead head dropper. Its dry dropper season on Boulder Creek! Bring a stimulator and a prince nymph and be prepared for a day of non-stop action!  The fishing is fair.  Clear skies and 60+ degree weather. The water temperature was between 40-43 degrees and Slightly Off.
