SWIM Themes

Once you launch the SWIM Digital Atlas, you will see a map of the entire Sacramento River watershed. On the right side of that display, you will see a drop-down box labelled "Jump To." This will allow you to other "themes" to display (a theme is a pre-defined area and map layers). The themes are listed below.
