Presa

[powerchisper]

It is different

Presa is for accumulating water ( dam )
Pantano is the "lake" formed by a presa

Dique is different . You put a ship into it and then you drain all of the water out , for repair or for a water level shift.

I agree , presa as " female convict"

"Presa ibérica" is also a piece of meat , that comes from the "armpit" of an iberico pig ( delicious by the way )
