Survival quiz finding water in the wilderness

The question is, how do you find water in the wilderness? In the following video example there is a dried up creek bed with evidence that water had been there – such as small pools and discolored sand.

The video was taken in East Texas, just north of Jasper.  Over the past month the lack of rain fall has pushed the area into drought conditions.  Creeks and streams that normally flow all year long have dried up.  Hikers and campers that were depending on those creeks as a water source are going to be sorely surprised to find them dried up.
