Call Duck Pond Size / Depth?

[doodleduck]

Hi could anyone give me some advice about what depth and size call ducks would like for a pond? It would be for about 6 of them. They like to dive but I don't want to make it too deep if that's not what they like. Everywhere I look is for larger breeds of ducks.
The excavator guy showed up today unexpectedly so it's all happening much sooner than I planned so any advice wou be appreciated!
I've got a drainage system in place, I'm going for more of a bath type idea with a plug to drain it regularly due to my size constraints I can't make something huge that would clean itself naturally like a naturally occurring pond / lake.
Thanks!

Oh also! Anyone know what a good size run would be for 6 calls?

If I was making a duck pond I would make one end shallow so they can stand and do their bathing, and one end deeper for swimming and diving. You probably already have yours dug!
