The Park re-opened its fishing season three days ago. Crowds are not up to usual amounts. This means that such popular locations like the Firehole River and the Madison River could be more enjoyable to fish. Streamer patterns will be your best bet for migrating browns in the Madison River. Likewise for migrating browns in the Gibbon River, Gardiner River, Snake River, Lewis River, and Yellowstone River where low light conditions give the best chance for action on each. Afternoon BWO hatches will dictate how to fish on the Firehole River. If you do not mind the long drive, now begins the fall season on Trout Lake. Colder water will convince lunker hybrids and cutts there to take leech and damselfly nymph patterns. Make sure you watch the weather in that neck of the woods before you go.
