The Challenge: Identify items on Syrian banknotes

I am cataloging the Central Bank of Syria's notes for publication in The Banknote Book, and I have been unable to identify a few items which appear on these notes.

The back of the 100-pound note dated 1966-1974 depicts a dam. What's the name and location of this dam?

The front of the 5-pound note dated 1977-1991 depicts a female statue.
