Current Streamflow : Upper Big T at Moraine Park: 14 cfs, Big T above Lake Estes: 33 cfs, Big T Below Lake Estes: 41 cfs

Highway 34 is closed at the canyon mouth until Memorial day! This will limit access to the Big T, and you will need to go around to Hwy 36 to get up to Estes. For more info on the closure check out:

The Big T below Lake Estes is at a good level right now. Fish are keying in on typical sub-surface tailwater patterns and smaller leader and fluorocarbon tippet should be used directly below the dam.  As water becomes more clear and temperatures fall, nymphing small midges and baetis will become most productive. be sure to use stealth indicators and switch up the amount of weight you're using in this section to make sure you're getting in the right zone in a stealthy way. Arm yourself with a midge cluster or a few small dry fly patterns in case you find fish keying in on hatching midges or BWO's.

Moraine Park and the Big T above Lake Estes has been flowing at a lower level as fall continues. Fishing dry droppers and streamers this time of year is going to be the best way to fool fish as water temperatures drop. The nice thing about lower water temperatures, is that fish start to realize they need to be packing on the pounds before winter so they will eat more aggressively. Smaller baetis, worms, and midges tend to do the trick on the Big T but and don't forget your streamer box this fall!
