FlyCast River Forecast
Difficulty: Beginner/Intermediate
Winter is in full swing and flows are low (10 cfs) on the Big Thompson and as a result, your options are limited. While you can still find some open stretches below the tailwater section, your time will be better spent fishing the tailwater stretch below Lake Estes dam. There is less ice buildup and trout are relatively active. The morning hours have been slow due to freezing overnight/morning temps but as the day progresses, trout will become more active. During the 11 am 3 pm window, trout are stacked up and feeding in the soft pools, runs and pockets. These trout typically arent spooky or selective, but accounting for low flows and clear water, plan to work a little harder. Small (#22-24) midge larva and pupa patterns have been the most productive. Baetis and searcher patterns such as Mercury Flashback Pheasant Tails, JuJu Baetis, Guides Choice Hares Ears, Frenchies and small stones are productive lead flies if trout arent responding to a double midge setup. Miracle Midges, Bling Midges, Black Beauties, Top Secrets and Chocolate Foam Back Emergers are our go-to midge patterns. Focus on getting your flies deep early in you drift and youll find a few trout willing to play.

FlyCast River Forecast
Difficulty: Beginner/Intermediate
Winter is in full swing on the Big Thompson and as a result, your options are limited. While you can still find some open stretches below the tailwater section, your time will be best spent fishing the stretch below Lake Estes dam. There is less ice buildup in this stretch and trout are relatively active. The morning hours have been slow due to freezing overnight/morning temps but as the day progresses, trout will become more active. During the 11 am 3 pm window, trout are stacked up and feeding in the soft pools, runs and pockets. Sitting at 16 cfs, flows are low and water clarity is high. These trout typically arent spooky or selective, but taking those two things into account, plan to work a little harder. Small (#22-24) midge larva and pupa patterns have been the most productive. Baetis and searcher patterns such as Mercury Flashback Pheasant Tails, JuJu Baetis, Guides Choice Hares Ears, Frenchies and small stones are productive lead flies if trout arent responding to a double midge setup.
