What measurement symbol is used to depict a seasonal stream?

The symbol used to depict a seasonal stream is represented by a single broken blue line. This depiction helps users of maps easily identify seasonal waterways that may not be present year-round, reflecting their intermittent nature.

In map reading and terrain operations, color and line types serve specific purposes; blue typically represents water features. Therefore, a broken line denotes that this is not a permanent watercourse, indicating that the stream flows only during certain times of the year, such as after significant rainfall or snowmelt. Understanding this representation is crucial for planning and navigation, especially in areas where water availability may change significantly with seasons.

The other options do not accurately represent this characteristic. Solid green lines often suggest vegetation boundaries, broken red lines may indicate manmade features or hazards, and dashed yellow lines are usually used for different types of roads or pathways. Each of these serves distinct functions on a map, but only the single broken blue line correctly identifies a seasonal stream.
