Colorado Stream Update: Colorado fly fishing has been a little snowy lately but the sun is out today! Fishing on the famed St. Vrain has been fair to good so get out and fish!

Current Conditions at Saint Vrain:

Colorado's St. Vrain is one of the most iconic and infamous small streams in the west and for good reason! Lots of fish and epic insect hatches make for a great western trout stream. 7.5 foot leaders 4x-5x tippet.

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. 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. Use a long 9’ or 10’ rod to get the most control out of your nymph rig. To imitate a midge cluster try using a Griffith’s Gnat (size 18-24). 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 slow.  Clear skies and 20-23 degree weather. The water temperature was between 32-35 degrees and Slightly Off.
