Watching the River Flow

You know those amazing National Geographic poster-sized maps that explain everything about Ethnoliguistic Africa or The Ocean Floor? This map of the Colorado River Basin by 5W Infographics, is a recent addition to the NG online map collection.

What’s so cool about this map, is that overlaying the river, is a chart, where the width at any point corresponds to the amount of flow at that point in the river—the wide band shows averages for wet years, the narrower darker blue band shows the amount for dry years. You will also find out, in incredible detail, everything else you might want to know about this river basin that supplies more water than any other river basin in the world. The maps are all zoomable and high-res, but sometimes take a bit of time to render.

Yet another incredible resource from National Geographic.

Here are a few others from the collection
