Water can be found and collected in numerous ways. You should stay on the move until you find a source of water. Streams, lakes and rivers are going to be the most obvious sources. Listen for the sounds of a river. They can be heard in the quite woods from miles away. Also keep in mind that water always flows downhill, so look for valleys and low-lying area’s as a good chance to find water.
Watch the wildlife. Animals always know where the water is so look for animal tracks /swarming insects are also a signal that a water source may not be far away.
Vegetation is another thing to steer towards. If you see lush green, its a good bet that a water source is nearby.
If easy sources are not available, a bit more ingenuity will be necessary.
