I ran The Numbers through #5 at 350 cfs at the beginning of the season and found it to be lusciously deep with plenty of water.
I have been getting into some shallow fast creeks this season, so my perspective may be skewed.
But 350 cfs seemed to be a fun level, and not too bony.
Only a couple of places between rapids where you had to pay attention to stay in the channel and not bump.
Also, some of the rapids did involve slight rock contact, moreso than when I ran it last season at 1000 cfs.
Some have said that it does get very bony beneath #5 at 350ish, although I cannot confirm.
We took out after #5 to be safe.
