When I did this a couple of years ago the fences are easy seen and avoided, not sure if any new fences have been added.
It is a senic ranch kind of a run. In the upper stretch, depending on level it might be tighter and faster then FP, with one harder (not to hard) III rapid. I ran it at 250 and 350. I recommend 350. There are a couple blind corners, but scoutable, if you don't want read and run.
I heard from someone this year that Seaman's res is way down and it kind of runs like a creek through most of it? Typically, you have to paddle a mile or so across the res.
Below the dam, it seemed III/III-ish to gateway park.
Watch out for rattlers on shore.
