The hopper bite was excellent on the Yellowstone yesterday. Fish were chowing down a peach colored Yellowstoner. (That’s a big foam rubber leggy thing.) There were also fish rising on the flats and along the banks. Unusual on a hot, sunny day in August. We caught a couple on a #16 yellow parachute where we saw rising fish. No real hatch, just fish eating dead stuff in the surface film. A #14 pheasant tail dropper worked well until late afternoon, then it was all about the hopper!
