Winter Fishing Update: Big Thompson 

We are starting to see Spring knocking at our door with the occasional warm weather and this coming weekend will be a great weekend to get outdoors. Temperatures are expected to hit the 50's and I know we are all hoping for some open water. Most of the water in the Big Thompson Canyon will be located below Lake Estes. As you drive up towards the damn be on the lookout for any potential of open water that is on public land to fish. If you tend to get out more in the mornings be prepared to nymph with small nymphs and emergers like Two Bit Hookers, RS2's, Zeba Midges, and UV Emergers in size #18-22. These are the perfect imitations of what fish will be eating. As you work closer to the dam scuds, small worms, and leeches can play a big role in your success of getting fish to eat. Carry a couple of small indicators to avoid spooking those weary trout. We love the New Zealand Strike Indicator kit as well as the Palsa Pinch-on indicators. As the weather warms and the sun begins to come overhead keep your eyes peeled for any hatches that may start. Expect to see midges and potentially small pseudo baetis. As long as you have flies like the Stillborn Midge, Mole Midge, CDC Baetis Duns, and Sparkle Flag Blue Wing Olives in #18-22's, you should be able to manage a couple of dry fly eats if fish are nosing at the surface. Of course you can feel free to call us for a report and if you do get out please share your experience with us. We will just have to live vicariously until we can get out ourselves. Have fun out there and enjoy the nice weekend!
