The river is in pretty good shape from the top down to Simms at least. Some larger fish have moved up from the lake to get up and spawn in the tribs. With great weather in store, you could have a great day. Mid day we are seeing some Blue Wing Olive hatches. Good flies are the #18 Zebra Midge, Sweet Pea in #16, and the #18 Olive Hotspot. Also Rubberlegs. Some of these fish are pretty aggressive, so swung an stripped Sculpin patterns are definitely a good idea now.
