Anyone know what this is?

I've noticed a couple of these in my man-made waterfall in my front yard. They swim real well and I've only seen them underwater.

Are those dragonfly nymphs? Just a guess.

That would be my guess as well. They are pretty cool predators.

Definately young dragonflies. No doubt.
