Krishna:
The driest section is the first few miles, to Mehrten. There is no water available at the trailhead, so I would top up the liter at or before Giant Forest. I think the descent from Chagoopa to Kern Canyon is dry, too, so I would top up before leaving Moraine.
I would also adjust mileage to avoid Bearpaw: the BP camp is a drop from the trail, has no view, not much to recommend it at all.
