Should be open october through march
If it's closed year round that's news to anyone up here and something new, restrictions have been from april 1 to sep 30. Usually get a week or two of flows in October, never seen it iced out before april 1. One gorge dumps under a huge boulder suspended between the walls, everything else goes if your up for it. I wouldn't put it past the park service to change shit without notice. Last I knew this was the only resticted water in the park.
