I have seen a lot of pictures of ponds that look like they were just plopped down in the middle of a yard. Well they don't look that way, they are that way.There is nothing around them and the waterfalls usually just come out from a mound of dirt or rocks that is about as wide as the falls itself. My advice to "would be" pond builders is to set the pond off from everything else. Try to build it with a backdrop of some sort, A fence or garage anything that will stop the eye from seeing behind it. If it has to be built in the middle of the yard then plant something or put something behind it, and not just the width of the pond, but wide enough to keep the eye trained on the pond. There are ponds that look good that do not have anything behind them but they are in the minority. Here is a picture of a friends small pond that is only about 6 feet long and three feet wide. They have two falls one in the back and one from a small rock on the side.
