My take is it's basically mimicking all the other runs on the FR. So Boulder Creek is dropping, Poudre main is dropping, and CC is dropping...all in all doesn't look good for it staying up till thurs, but who knows. You can check the bottom gauge from the canyon and I wouldn't go in less than we had (although I hear people have), and when I go back I'll definitely wait for more water (like 2' on the bottom gauge and 85-90 on the upper gauge). Cool wilderness run though, super beautiful. Even saw a moose.
In regards to your other post too, there's nothing all that difficult and there aren't many options of lines so you'd be hard pressed to need a guide. The two log portages are easy to spot with good eddys and all the drops are straight forward.
