Well ur defenitly in a good situation on private land with lots of ducks everywhere.  I would keep it simple no more than a dozen mallard decoys if that, maybe even a half dozen would be okay if the pound is really small.  Place them in lil pairs or groups on one side of the pond.  Anything to give you motion on the water would be awesome too like a jerk string or some of those wiggle feeder butts. Use simple quacks or a greeting calls to catch their attention.  Then let them check out the pond and hopefully they like what they see and come on in.  The key I think will be motion on the water if there is no wind, u want some ripples in the water to make it look like ur dekes are active.   Hope this helps.

You might be surprised if you look around Midland. I was born and raised in the town next door (Odessa). I know there's not allot of water around, but what little there is attracts a good number of ducks (for the area). Look south of i-20 for a place that Monahans draw runs through a property then contact that landowner. Here's my duck hole in Midland on the draw (family land, not for lease unfortunately).
