This presentation explains and illustrates how to identify and draw watershed boundaries on a topographic map. The process is explained step by step in the next 16 pages. You should review this presentation until you have a good understanding of the process and then test your watershed delineation skills using the two additional topographic maps provided in pages 18 and 19 of this presentation.

The correct delineations (i.e., the answers) for those two watersheds are provided on the last two pages of this presentation (pages 20 and 21). Note that the delineation of the second test watershed is more difficult than that of the first because the landscape is flatter, which makes the features shown by the topographic lines less obvious.
