I have been doing a series on ducks and this is the last leg of a 3 part series. 

When you dig a stock tank on your ranch or lease does it have to be just for ducks or fish or can it be for both?  Dedicated duck hunters will argue that the perfect duck tank or pond if your from up north, needs to be shallow with a large surface area.  Fisherman want a deep pit and something that will support catfish and bass and be sustainable through some of the many long droughts we suffer in South Texas.
