I was up there two weekends ago and there was water flowing above Fish Creek Trail Camp. Not a lot, but plenty to fill bladders etc. Not sure about water at the camp, though.
Worst case, there are a couple of water sources on the way to camp -starting from either the Aspen Grove Trailhead or Fish Creek Trailhead- which wouldn’t make for too bad of a water carry.
Looks like it’s going to be around 65-70 degrees at that elevation.
If you aren’t yet aware of this site, it’s a good resource for weather. Here is the temp forecast for San Gorgonio. It shows temps for a few different elevations too.
The other good site is Ben’s Weather.
