Current Streamflow : 25 cfs @ Big T Above Lake Estes,  22 cfs  @ Big T Below Lake Estes, 7 cfs @ Moraine Park

Winter is here bringing cooler temperatures and more selective fish, especially as you get closer to the tailwater section of the Big T.  BWOs and midges are becoming more prevalent with more cloud coverage and cooler temps.  Be sure to have a variety of dries, nymphs and emergers in your box as the fishing changes. 

For dries, small BWOs and midges are producing fish early in the morning and late in the evening.  During the middle of the day, a dry-dropper rig or indicator nymph rig will be the most productive when searching for fish and locating where they are in the water column. 

This time of the year streamers can also be productive, as fish are preparing for the winter months when there is less food.  These next few weeks are going to be much cooler, which can make for some incredible streamer fishing as fish become more aggressive. Sculpzillas, Thin Mints, and Sparkle Minnows are great choices to entice those bigger fish to eat.  Have fun and happy fishing!
