The fishing on Lewiston has slowed quite a bit in the last couple of weeks. The best action will be when the sun is off of the water. Callibaetis and a ton of midges are coming off up here. Red Zebras and your favorite Callibaetis emerger on an Intermediate line is the best method now. Keep some dries handy for when the fish are looking up, the Milla Time Callibaetis is a good fly for that. Stripping leeches or Wooly Buggers can also be productive during the day.
