Orvis Cherry Creek's Tip of the Week

Winter is here! Weather is in the 40/50’s degree. This time of year, midges, BWO and stoneflies are hatching. Dry fly fishing is slowing down, usually in morning and late afternoon! The flow will fluctuate depending the downstream water needs. The flow today is 145 cfs. Happy to say that browns are starting to pair up for fall spawning. Watch out for the redds! With the lower flow this time of the year, trouts are feeding hard before the cold weather sets-in. Fishing is better above the bridge or below Tumbull! After the last Spring storm that washed down sands and debris from the hill side, below the bridge and at Hole in the Wall, there are too much sediments. The best time to fish is between 7 am to 7 pm. Trouts are still feeding in the riffles! They are spooky and picky! The trouts are more concentrated at the riffles and front part of the run. Don’t go straight to the deeper prime water! If you watch carefully, the trouts are concentrated next to the river bank. Fish will key on particular flies, midges (size 20-22) and BWOs (20-22) through out the day. Mercury midges, bling midges, Top Secret emergers, Chocolate Thunders, RS2's and all small beatis patterns are proving effective. UV scuds, worms, eggs, stoneflies, and brown and olive leeches are great attractors. Late morning, watch for hatches! Dry flies fishing should start late morning and/or the late afternoon if and when you see hatches Micro San Juan worms and eggs are the effective flies! A small little bird told me that a small white midge with flash works really well right now. Please handle the fish with care!

5-Day Outlook as of 11/21/25

Deckers is coming back to life! The Winter flow is around 145 cfs. This is really a flow for trout fishing at Deckers! Trouts are spread out every where. The flow will fluctuate quite a bit in the upcoming weeks. Use midges, stonefiles and BWO all day! Watch out for dries with the cloudy days. As we head into fall, larger brown Trout will be more active in preparation for spawn. While fishing dry flies is a great choice, start thinking about streamer fishing as Brown Trout become more aggressive. Dress in layers this time of year!

Techniques & Tips as of 11/21/25

For Winter fishing, fish generally concentrate on the runs below pools. Early in the day, small midges, caddis and baetis are the ticket, smaller diameter tippet and adjusting depth frequently are the key strategies. Match the hatches!! Fluorocarbon tippets in 5 & 6 and even 7X are most effective for nymphing. Utilize heavier split shot or larger tungsten head point flies to get down deep, adjust depth prior to switching patterns. If you are not having success with the micro flies and midges, throw out scuds, leeches, eggs or worm. I like to use mini leeches to entice the trout especially when nothing is working! If you see some action on the top water, Adam’s, no mercy midge, mole flies and Matt's midge are the keys. Adams and Griffith’s Gnats are great dry flies to use in the early and late afternoon! With the flow this week, try a few larger patterns like eggs, worms, stoneflies and leeches. Additionally, make sure to include streamers in your approach. Fall spawn is here, making brown trout very aggressive and willing to chase after prey. With streamer fishing, make sure to focus on the river banks, strip streamers through deep pools, or even try drifting a jigged streamer through a fast riffle. Come see Gene or Mike at Orvis Cherry Creek for more information!
