Sallies are coming off like crazy on Grey Reef top to bottom. Seeing good numbers of caddis and pmds as well. Fish are STACKED in the riffles and fast water!!! These fish have also been more than willing to chase and eat a streamer. We are also starting to see a decent number of fish on top eating caddis and sallies. It might be getting close to big dry/small dry time on the North Platte….
