In the 30,000 - 40,000 range.... Big but still have time between drops to get your game right. Always thought that the 20,000 - 30,000 range was not as hard as lower or higher flows (just me).
Always thought Cat was in a league of its own. several days of flat drunk water then 1 - 2 days of intense water with a few scouts then flat lake water with head winds.
Check lake levels and talk to commercial companies to get the latest on rapid situation below Big Drops and camping below Imperial.
Be aware of #5 left side can be a mother of a hole at certain levels (been there done that)
