I was surprised at the rivers in the middle of the Sahara.

But upon zooming in on Google satellite view, I do see dry riverbeds in those places, and even the occasional tree along the route of the 'river', so I guess occasionally there must be a storm and those rivers become wet and flow.



Similarly i was surprised to find its marked a river in my village i didn't know existed.

Turns out its the drainage ditch they dug to stop the new Barrett boxes from flooding.

I think the data may need some work....

Well If you want to, mapping around local village is good way to start.
