Getting ducks to my tank.

We're got about a 2 ac tank that we built a year ago and have not see any ducks on the water. I've tossed out some decoys and set up a camera but still no signs.We've got lots of other birds but no ducks. So I was seeing if y'all might have any pointers that might help me.

Thanks

Corn!

Start planting this spring. Or wait till mid September next year and plant wheat and rye grass all around the bank. Heavy on the Rye grass. Had Teal all over my Rye grass today
