Orvis Cherry Creek's Tip of the Week

Spring time fishing is probably the best time to fish. However with the storm that brought torrid rain and snow a few weekend ago, fishing in Deckers is coming back slowly! Sand and mud were washed down from the hillside caused by the recent storm. Weather is in the 60’s and 70’s degree this coming week! This time of year, midges are a touch bigger, BWO are hatching and caddie is starting to hatch. Dry flies fishing is coming along great, usually in late morning and afternoon! The flow will fluctuate depending the downstream needs. The flow today is up to 92 cfs. This year the trout are smaller than the past years! Trouts around 12 to 18’ are generally caught this year whereas in the past, large trout around 20” plus are readily available! The best time to fish is between 7 am to 7 pm. With the warmer weather, start up-sizing the flies to 18, and 20. Trouts are now feeding in the riffles! They are less spooky and picky because of the hatches! The trouts are more concentrated out with the lower flow. Fish will key on particular flies, midges (size 20-22),BWOs (20-22) and caddies through out the day. Mercury midges, bling midges, Top Secret emergers, Chocolate Thunders, RS2's, caddies and all small beatis patterns are proving effective. UV scuds, worms, cranefly larvae, 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! Please handle the fish with care!

5-Day Outlook as of 5/23/25

Give Deckers is coming back some from the previous storm. The silk is concentrated at the middle of the middle of the stream. the flow is down to 92 cfs. This is a bid lower flow for trout fishing! With the coming weeks with the Spring runoff, the flow will fluctuate quite a bit! Use midges, caddis and BWO all day! Watch out for dries with the cloudy days.

Techniques & Tips as of 5/23/25

For Spring/summer fishing, fish generally concentrate on the riffles with the lower float right now. Small midges, caddies and baetis are the ticket, smaller diameter tippet and adjusting depth frequently is a key strategy. 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. With lower water level, use smaller indicator! If you're 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 trouts 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, 5X and 6X will catch you a lot of fish. Come see Gene at Orvis Cherry Creek for more information!
