Colorado Stream Update: It is cold & breezy in beautiful Boulder, CO this morning! But if you are tough enough there are still plenty of wild brown trout to be caught in the open sections of the creek through town!

Current Conditions at Boulder Creek:

Fishing has been fair to good on Boulder Creek this winter, look for trout to be in the slowest seams and pools. 9 foot leaders and 5x tippet. A combo we have had great luck with this winter is a Parachute Adams size 20 trailed by a variety of bead head midges size 20-24. Good luck and have fun!

It is cold in Denver, Colorado the fishing has been good but make sure to have a warm hat and a good pair of gloves. No need to be on the water early, wait for the sun to come up in order to warm up the water temperature. Fishing has been best from 10 a.m. to 2 p.m. and fly fishing trips have been catching lots of trout. The fish are feeding mostly on midges during the midday hatch hours. Make sure you are getting a good drag free drift in order to hook fish. Tiny tippets and small midge and mayfly patterns are hooking the most fish. Try nymph fishing with different styles and sizes of midge patterns. Try a tandem nymph rig. Use three different midge patters. Try a black Zebra Midge (size 20-24) or a Money Midge (size 20-24). An egg makes a great point fly during the winter months. Use a bright colored but small San Juan worm in red or pink to help you see where your flies are drifting. The fish are pooled up right now. Look for fish holding in the slowest and deepest runs and holes in the river. Fly fishing reports are good. To imitate a midge cluster try using a Griffith’s Gnat (size 18-24). Look for fish rising during the warmest part of the day. The low and clear winter water makes for excellent sight fishing conditions. Make sure bring a quality pair of glasses to cut the glare from the snow and sun. The winter fly fishing in Colorado is great.  The fishing is fair.  Clear skies and 24-27 degree weather. The water temperature was between 32-35 degrees and Slightly Off.
