Lowest I've ran it is 412 I think. Scrapey in a few places including the paddle out but everything still goes. As long as it doesn't get much below 400 I'm still going Sunday. Griffin you interested in a low water Gore trip Sunday? Or have plans for it already?
P.S., sorry for turning this into a threadjack Scott. By the time you get your boats up here, or work out something to borrow boats there should be enough water in the Arkansas to get you at least a worthwhile introduction to boating here.
