Quick Answer
To find water using a map, identify potential sources like lakes, rivers, and streams, then use contour lines to locate areas with low elevations and high water flow, which often indicate water sources. Look for vegetation and topographical features that suggest water presence. Use a compass to cross-reference with the map.
Reading Contour Lines
When using a map to find water, contour lines are crucial. Look for areas with closely spaced lines, which indicate steep slopes and increased water flow. Identify the 100-foot contour interval, which often marks the bottom of a valley or a stream. Use this information to locate areas with potential water sources. In a desert environment, prioritize areas with a slope of 10-20% or more, as these often indicate water flow.
Identifying Potential Water Sources
To identify potential water sources on a map, look for the following features:
- Lakes: These are often marked as “L” on the map.
- Rivers: These are often marked as “R” or a blue line.
- Streams: These are often marked as a blue line or a smaller blue dot.
- Springs: These are often marked as a blue dot or a small blue circle.
- Low-lying areas: Areas with low elevations and high water flow are more likely to have water sources. Use a compass to cross-reference with the map and identify potential water sources.
Desert Water Priority Rules
In a desert environment, water is scarce and precious. When using a map to find water, prioritize the following:
- Low-lying areas: These are more likely to have water sources.
- Areas with high vegetation: Vegetation often indicates the presence of water.
- Areas with topographical features that suggest water presence: Look for areas with steep slopes, closely spaced contour lines, and other features that suggest water flow.
