There is plenty of water at Summit Meadow, on the West side of Olancha Pass. But access to the creek at the bottom of the approach canyon can be difficult, if not hazardous, as you can see from the topo. Take plenty of water from the start, and leave very early in the morning; it will be hot later in the day. There is another stream crossing just below the pass, on the East side, but it is often dry.
