High whitewater boating flows are scheduled for Pit 5 two weekends in September.  On September 6-7 the flows will be 1,500 cfs and on September 20-21 the flows will be 1,200 cfs.  Normal flows are around 400-500cfs.  The high flows will only be in Pit 5, so if you want to go fishing on those weekends you should consider fishing Pit 3 or 4 instead of Pit 5.
