It’s a cold, stormy opening here. Snow and rain mix happening along the Firehole River, a favorite early season destination. Look for caddis and a number of different mayflies emerging in big enough numbers to provide action. Streams are mostly in good shape because of the warm spring and a bit below average winter snowfall. I’d wait for warmer weather before trying streamers for those big Lewis River channel browns or getting out on Yellowstone Lake trying for lake trout to be converted with a beer batter to delicious table fare.
