Current Streamflow : Upper Big T at Moraine Park: 433 cfs, Big T above Lake Estes: 853 cfs, Big T Below Lake Estes: 637 cfs

The majority of the snowmelt has made its way through the park and into the Big T. We will continue to see high flows as the rest of the snow dissipates but for now, flows in this area have begun to level off and we should start to see a steady drop as we inch though summer. Fishing below Olympus Dam, although still high, will continue to clear up and is still a great option to escape from high flows in the lower Poudre. The inconsistency in flows throughout the tailwater section has had some people heading toward Moraine Park and higher. The mainstem through Moraine Park is really high but tribs flowing into it have been fishing really well. Be sure to focus on the soft edges and backwater here to find fish consistently. As for the high country, lakes and streams are open and flowing, just keep in mind this water is still really chilly and we are still waiting for these fish to wake up from the winter slumber, so fishing may be slow the higher in elevation you venture.

In any of these areas, small attractor/stonefly nymphs like Hotwire Princes, Purple Princes, and Chartreuse Copper Johns fished under smaller Chubbies and PMX’s is a great option for searching the water. Caddis pupa, big stoneflies, worms, and some tailwater bugs are good to have with you when fishing the section below the Dam under an indicator with 4-5x tippet to account for increased clarity and pressure through this section. Throwing a few tailwater bugs in the mix never hurts here either. As we continue into summer, attractor dries and terrestrials will become a go to both in the high country and low down on the Big T.
