Dont know if this helps, but I called a local Fu guide service today (setting up a trip). They have a gauge near camp, and a good strong reading is 80. They said the gauge was at 240 today and no one was on the river.. i.e. BIG !
I guess the lake is nearly full and they are letting a lot of water out of the damn. There has been two weeks of rain plus the snowmelt. They said that it comes down pretty quick after it stops raining..
It would be cool to find a gauge on the web somewhere...
