Big Thompson River Below Lake Estes:

The Big T is fishing very well right now.  The flow is into Lake Estes has been around 486 CFS this week and out of Lake Estes the flow is currently 379 CFS.  Nymph setups are the best right now with the higher water.  Pink Squiggle Worms, Green Ticket, Sow Bug, Perdigon, or CDC Pheasant Tail all have been productive.  Mix those with Radiation Baetis and Blue Poison Tung.

Check Flow

Mary’s Lake and Lake Estes:

Mary’s Lake and Lake Estes have been fishing well. You can catch some nice fish if you fish the Power Plant outlet area as well as the inlet area. Fishing in the open water has been good as well. Egg patterns, Hares Ear and Squiggle Worms at the inlet have been productive. The Sucker spawn is on so yellow to chartreuse egg patterns are good.

Rocky Mountain National Park:

Rocky Mountain National Park is OPEN! Check with the Park for their new entry protocols but the fishing is very good. Several of the high mountain lakes are ice off and ready for fishing. Fern, Dream, Spruce, the Loch and others are fully iced off. Small terrestrials and worm patterns were very productive in the first days of fishing up there. The flows in Moraine Park are getting high so look for soft water on the edges.
