The St. Regis river is fishing well lower down as the Brown’s are starting to show up. Fishing higher should still see results for Rainbows and Cutts on smaller attractors such as Royal Wulffs or red Madam X.
The browns have moved into the lower St.Regis river. Consider streamers and a sink-tip line to get down to the nesting spawners.
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.
