Yellowstone Park

All Madison River drainange streams are in good shape. This includes such as Duck Creek, Maple Creek, and Grayling Creek. The Firehole River is a destination and is producing well. Several mayfly species and caddis are emerging and providing action. Fall River Basin streams appear to be in good shape, but a lot of snow remains on the Madison and Pitchstone plateaus. When weather really starts warming expect all these to start showing run-off.
