Big Thompson River Report

Big Thompson River Report

Current Streamflow :  55 cfs @ Big T Below Lake Estes, 26 cfs @ Moraine Park


Spring is in the air! We are starting to see more consistent dry fly action in the form of Baetis, small Caddis and of course Midges. Fishing has been great from Olympus Dam to below Drake. The water maybe off color below the North Fork due to snow melt run off. Smaller flies and tippet are still gonna be the most effective. Fishing is better later in the day once the water warms, as fish tend to be more active with warmer water temps this time of year. 

Productive Flies: Flashback PT #14-20, Pats Rubber Legs #10-16, Mayhem Midge #18-22, Blue Poison Tung #18-22, Sow Bugs #14-18, Perdigons in Olive, Brown and Yellow #16-20, Duracell #14-20, Black Beauty #18-22, RS2 #18-22, BWO #18-22, Parachute Adams #18-22, Matt's Midge #20-24, Smoke Jumper #18-24


Winter weather here in Colorado continues to ebb, and the spring temperatures are arriving in full force. As the snow continues to melt in the high country and feed the Big Thompson, the water level has risen and the current is getting faster by the day. Of course, the weather isn’t warm enough to warrant a large population of fish in all areas of the river, but a more experienced fly fisher should have no problem locating certain pockets of water with numerous fish. On the warmer days, you can expect fish to venture from their winter hallows and into the main stretches of river in search of a meal. Making sure to grab the right flies is a crucial part of successfully fishing the Big Thompson River as the water levels rise, and more and more insects become prevalent to the diet of the fish. For now, Angles Sports recommends carrying a wide variety of midge imitation flies, as Trout are known for their midge appetite, and susceptibility to midge imitations. Feel free to stop in at our Longmont location where a fly fishing expert can help you select the right flies for the Big Thompson River - or anywhere else you might be interested in.
