Anyone know the type of plant this is?

Hi everyone, I'm new here and honestly, I'm not sure if I found the right forum or not. My parents have a large pond behind their house and they are having trouble with a plant taking over. It grows pretty quickly. As of right now they are just pulling it out every few weeks but It's getting to be hard on them. Anyone have any idea on what this is? We are in South Louisiana if that matters any...

As a young lad growing up with my Grandmother she use to call that plant (berro) but that is in Spanish, it is a plant that loves water.

It would be the Watercress, maybe? Nasturtium officinale?
