Crowds should begin thinning after this weekend making travel more timely to fish so many waters. For many streams it is trico activity in the AM and caddis life cycle and terrestrial insect patterns in the PM. Most of the big cutts have moved back into Yellowstone Lake from the river. Hebgen Lake browns and ‘bows are migrating upstream in the Madison River drainage. Soon wading the Lewis Lake shoreline will give a chance to encounter migrating brown trout. Beula Lake will remain among the fastest fishing locations in the park through most of this month. Most meadow streams will feature trico activity in the AM and terrestrial insect in the PM. Stealth will be required as these waters are nearing base level flows.
