It will take about an hour to 1 1/2 hours for the water to go down after they shut it off tonight. I would use a 5 or 6 wt rod with floating line and streamers. Streamers to include but not limited to mohair leaches, slump busters, pine squirrel sculpins, wooly buggers and so forth. Definately bring white. Some other colors to have are olive, black, purple, and red. Size of the streamers should range from 6 to 12 both weighted and none weighted. If you know the area very well then the flats between outlet one and two should be good and the lower part of the gauntlet below the downed tree to the point should also be good. Dont forget to fish the shallow water behind the point also. To fish the streamers I would start by casting directly across the current and just let it dead drift through the swing then strip slowly back in. Also try quarting the current down stream and let dead drift then strip back in. If those done produce for you, try varying your retrieve. If you dont get a bite in 10 casts, change something up, either color, weight of fly, or retrieve, until you find out what and how the fish want it.
Good luck and be careful
