Latest Update: 5/23/2017.
We will update these reports as often as necessary to keep our fellow anglers in tune with changes.

Current Streamflow : Upper Big T at Moraine Park: 108 cfs, Big T above Lake Estes:  275 cfs, Big T Below Lake Estes: 128 cfs


**Highway 34 is closed until May 25th, 2017.  Continue reading our Big Thompson Report for more details.**

Flows below Olympus Dam are expected to continue rising as more water melts from higher elevations. With the subsequent loss of clarity, nymphing small stonefly nymphs with smaller Blue Wing and attractors have been finding fish anywhere the Big T can be accessed. With the recent bump in flows and extra moisture entering the system, a San Juan worm isn't a bad bet to turn fish. Dry-droppers are a great way to cover water this time of year lower in this system as well as higher in the park where the water becomes more diverse.  Small attractor dries like a #16 PMX or Chubby should get attention as our season continues to heat up, but still expect the majority of the action to come from the dropper. Midges and small emergers are always a good bet for the Big T, no matter what time of year your heading out, make sure you're armed.

If you're heading west from Loveland the Big T below drake is open and fishable up to one mile below Drake (mile marker 77). Make sure to have tippet ranging from 4 to 6x, split shot, and lighter indicators when heading here. As with any tailwater, sow bugs and other tailwater patterns will be productive under the dam.

US 34 is currently closed between mile marker 77 and 80. The closure is predicted to open back up after Memorial Day weekend! For more details on this, visit the link.
