“Construction of the Grand Ethiopian Renaissance Dam (known as Gerd) is now about 30% complete. Once completed, in three years, it will be Africa’s largest hydropower dam, standing some 170m (558ft) tall.”
Seth Dixon‘s insight:
Located near the border with Sudan (see in Google Maps), Ethiopia plans to dam the Blue Nile before the water heads to Sudan and eventually into Egypt. As stated in this BBC article (with a nice 1-minute video clip), Egypt and Sudan currently get the majority of the Nile’s waters because of colonial-era treaties and Egypt is opposed to Ethiopia’s plan, fearing their water supply with be threatened.

Do you think the water rise up to the sky without flowing down?

The water will eventually flow north to Egypt, but not if they use large amounts of that water (which is why Egypt is so concerned). Damming the river purely for hydroelectric potential though shouldn’t impact the flow too much though.
