The Madison River is fishing still really good. The hopper fishing has finally turned on there and with this warmer weather, it should last into the coming weeks I would use a size #8 more or less hopper in tan or pink I’d still bring your ants and beetles with you to trail behind your hopper or you can drop a #16 green or brown zebra midge.  If it gets cloudy throw a coffee sparkle minnow or a rusty trombone.
