Current Streamflow : Upper Big T at Moraine Park: 152 cfs, Big T above Lake Estes: 311 cfs, Big T Below Lake Estes: 272 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 Thompson (like everywhere else) is in the first stages of runoff! Flows have been rising steadily and will likely continue this trend with the upcoming summer warmth. Whether you’re fishing in the park, below Lake Estes or anywhere else it would be wise to stouten up your tippets and look to larger nymphs and small streamers for your fishing. Larger Ray Charles (#14-16), Poxyback Golden Stones (#10-14), and the ever-popular San Juan Worm (in a variety colors). Smaller Sparkle Minnows (#8) and Thin Mints (#8-10) are some good streamer options right now.
