There is only one location with water. About ~3 miles past CSL, the trail goes around a cirque under Cirque Peak. At that point on the map, the trail is heading due west, before it cuts north again.
On the map, just before you get there, it shows a small lakelet to the right of the trail (I've never been able to find the lake, BTW), however, to the left, there is a brook, with considerable flat spots for camping, and plentiful clean water.
Last time I was there, at the place to leave the trail, there was a cut off log that had "water" and an arrow pointing left carved into it.
This spot is not hard to find, but you have to know it is there.
One of my "special spots", treat it well......
