95 was for sure the big water year. 2003 rocked as well. It was closed for a few days to commercials, but we private boaters were crazy enough to get on it. R-4 a 14 foot self bailer at 3200cfs. The 2 in the front swam below 4 as we poured over the boulder (that should be above water) sideways, but they got back in. Damn it was moving fast.
The numbers is one of those rivers that does not flush when the level gets high. It gets angry and really wants to eat you for lunch. Putting an oar frame down it is without a doubt doable but I think it is best that you are a competant oar person and the level is within you comfort zone.
My husaband rows it in his 14 cat all the time, he is darn good and a whole lot of fun to watch. He has run it from 900-2800. He won't row anything below 900 to preserve longevity of his boat, and the squeeze in 1.5 is tough at that level. I only shred it.
