The building of the Karapiro Dam

Here is a YouTube clip of the building of the Karapiro Dam. While watching this clip, see if you can answer the following questions.

How long did it take to build the dam?
What river is the dam built on?
How many acres does the lake cover?
What was the concrete sealed with?
How much more power would the Karapiro dam generate compared to the Hora Hora station?
Why did they have to build a new highway?

RESEARCH:
