I talked to Kevco after the 95 season or during it (it's been a while). He was working as a guide on the Ark and then running the numbers solo at something like 4k for a few weeks during an incredible high water year. He told me it was still class IV ( which I thought was a bit of a down grade at the time). After catching it last year at 3400 I would agree it's still a IV, but from the top of 4 to about half a mile past 5 it's non-stop high end IV. He ran it higher and solo, day after day. I'm still impressed.
His death really got me thinking how fortunate I am to have such great people to paddle with here in Colorado. I mostly paddle with people from the club here in Colorado Springs, but have been on the river with many others. I may not say it often enough, thanks everyone.
