You can also find those links to Bob R's Whitney water sources in the Reference Forum, first topic:

    Links to important Whitney information

And just so you know, Bob R and many others don't filter or treat their water. No samples have ever turned up enough impurities to cause any harm. (I'd go to the Trail Camp pond inlet rather than just the pond, though.) You can find links to water discussions in the above "Links..." page, as well.

Since there are so many water spots below Trail Camp, you only need to drink at each spot, and carry a minimum. At Switchback 23, you should fill your belly, and carry 3 liters. I know some people will hide the third at the top of the switch backs to consume on the way back.
