A garden waterfall can add life and beauty to a backyard.
Map out the area for the waterfall and pond then contact public service and have them come in and make sure that your digging will not affect any power or gas lines.
Now start digging. It will be best to know what size you are trying for because you will want to dig it as close as possible to the size of your pound, especially if you are using the hard plastic pond liners (I will talk more about those shortly) as the base of your bond.
Once you have your hole there are several ways to create your lower pond and main water reservoir for the waterfall. You can get it professionally done with cement or try to do it yourself with cement, both of which can be very expensive and time-consuming.
Now the easiest way is to use the hard plastic pond liners that are out there. These are strangely shaped plastic molds that normally come in black and can be found in a wide variety of sizes and designs. They are generally shaped to give you several different depths of water in your pond and allow for a larger variety of decorations.
As you put the pond liner in you may have to either replace dirt or dig out dirt, but you will want to make sure it is a nice, tight fit, with no give. Remember you are going to fill this pond with a lot of water and if the liner is not tight it may shift position and ruin all your hard work.
Now you will need to create the upper pond. This is normally smaller than the main pond, although it does not need to be, just as long as it is elevated above the main pond. You can build the foundation up with dirt, decorative stones or bricks; just make sure that is stable.
Once more the easiest way to make the upper pond will be to get the hard plastic pond mold and make it securely fixed at the edge of the lower pond, elevated to the height you wish your waterfall to be. You can also space your upper pond away from your lower pond and set up flat stones or some kind of path for the water to travel through for your waterfall.
You will want to cut a gap in the upper pond on the side that the water is supposed to come out and flow into the lower pond. This does not need to be much of a gap, just enough so that it will be below the water level of the upper pond. If you have a path for the water to travel into the lower pond down, make sure your gap is not as wide as the path, otherwise use common sense so that your waterfall is falling into the lower pond, and not splashing out on the sides.
You will now need to get a water pump. Depending on the size of your pond and the amount of water you wish to have traveling down your water fall, that will determine what size pump you will need. Some pumps will not be able to push water very high, so if you have gone and placed your upper pond a good deal higher than your lower pond this will create the need for a larger pump as well.
Place the pump in your lower pond and run tubing from the pump into the upper pond. Secure the tubing so that it will not be moving around. The tubing will be out of the water in plan sight at this point, but do not worry; we can deal with that when we decorate the area around the waterfall.
Now start filling the lower pond with water and then turn the pump on. It is best to not run the pumps without water. As the pump goes it should star to fill up the upper pond. Once the upper pond is filled enough from the lower pond you will see the water running down in a water fall. The upper water level should become regular once it starts to overflow to the point that you get the waterfall. While the lower pond will most likely still need more water to get it to your desired water level.
Decorating around you waterfall can be real easy.
Plants of all kinds and decorative garden stones are easy to use to hide the edges of the pond and give it a more natural look. It is also best to hide the tubing from the pump this way since it will be outside of the water between the two ponds. Be careful about putting stone over it though, you do not wish to pinch the tubing and disrupt the water flow.
The plastic pond liners should have shallow area that is perfect for planting water lilies and such or having a piece of statuary coming out of the water. If you wish to have fish in you pond there are bio filters out there for just that.
All around the waterfall you can build the sides up with decorative rocks to make it appear as natural as possible.
Now you should have a unique addition to your yard that you can be proud of.
