The St Regis is holding some nice fish that head up river to seek out the cooler waters of the Regis. Fish a Royal Wulf while wading the drop offs. Look for feeding fish out in the faster waters under riffles. The Stimis are always a good St Regis fly in August . There are few mayflies in the air so stick with the attractors. You can get good wade access at Haugan offramp and follow the river up the dirt roads.
