I have 2 spots where I can dig my pond...one is in the woods and the other is in an area that has been cleared. My main concern is with critters getting the ducks if I put it in the woods but also could it being in the woods deter hawks. Would the pond bring water snakes and is there a way to help deal with them. Ive raised ducks and they are pretty hardy but this is my first time dealing with a pond. Any hints on getting it to keep water?
