I don't know what Mead is at, but when I did it in Sep/Oct '04, there was current for a day or so below Diamond, I think. Killer Fang Falls is down there - no seriously, that is actually the name. It's a simple drop, just back-ferry hard left and miss the rock fangs, but it might be underwater now if Mead is high enough.
We had a motor, so once the current died, we lashed three rafts together, the kayakers climbed on, and we putted down the river until the lake, which is very big and it was nice to not work on the way to South Cove and drink warm beer instead.
I would say it's all mellow for the most part. There are some small, non-big water type of class II and III drops in there; it's nothing significant.
The camping is the lame part. It's not all that exciting to camp on a mud flat, but it still beats being back home. Watch out for scorpions on the mud flats, esp. in the morning. We found lots tucked under one guy's boat, and they were the centruroides (pale ones) with the nastier sting.
Join up, suckas.
