The Firehole has been terrific for many of our customers. The fish are eating White Milller Caddis throughout the day when the water stays cold. Patrick guided on the Firehole yesterday and found White Millers as well as Baetis. Our upcoming warm weather should bring out solid morning and evening caddis emergences. You can swing soft hackles most of the day and pick up fish. Now is also a good time to go into the Firehole early in the AM and fish a wooly bugger. There has been good fishing from the top of the canyon to Biscuit but don't forget to check the temps when we hit this warm spell.
