How to Build a Waterfall

Sometimes when the day is busy or the mind is on vacation, I find it a good idea to rerun a post that was widely read the first time.
Today is one of those days.
So here is a post on how to build a waterfall from way back in 2006.



Building a waterfall is either simple or difficult depending on the point of view of the builder. We want them to look natural, like they just started happening in the rocks of our gardens, never mind that we had to buy the rocks because we live where no rock has ever been found like New Orleans where I live.

The easiest way to have a waterfall is to use a weir. A weir is a box that collect water that the pump has pumped into it. One side of the box is lower than the rest and has a lip on it so water will go over it.
These can be effective when building a waterfall. Simply elevate them above your pond, usually positioning them level on the dirt you have dug out to make your pond, put tubing from your pump in the weir.When the weir fills up, a sheet of water will fall over the weir and into your pond. You can hide the weir with rocks so no one can see the plastic box. Also, if you have a biofilter, you can put it in the weir. As an aside, if you do have a biofilter and use lava rocks in it, put them in several mesh bags, not just one. It takes several strong men to lift just one bag out, so use at least three. I usually float some hyacinths or other floating plants in the weir to further camouflage the plastic box.


Another, and my favorite way, is to start with a semi level surface, slightly raised in the back, starting at the same level as your pond. From there build the waterfall using the same kind of rocks you used in your pond construction. Start with large, flat and thin rocks. You can’t build a waterfall with round rocks or little ones either. After you put the first large rock down, run a hose over it to make sure the water flows into the pond. If it does not, shim up the back of the rock. If you don’t start on a slight angle, water will fall off the back and drain your pond dry in a few hours. Next, stack two or three thick and chunky rocks on each end of the bottom rock. Those rocks can be as much as 5 or 6” thick. Make sure they are flat on two sides because you are going to build the rest of your waterfall on top of them. If you have two large flat rocks on the ground level, you need more chunky rocks to rest the second level on. 

Next place the second level of flat, thin and large rocks on the chunks. Again run water over to make sure the flow is going in the pond and not over the edge. Continue making levels until you like your waterfall or run out of rocks. Make your waterfall as wide as you wish, remembering that you may need more than one pump.

I have found that the easiest way for me to build the falls is for me to be in the water and have a couple of strong helpers placing rocks for me. 

The back of the falls is equally important. Shimming must be done to keep the angle toward the pond and proper placement of rocks is most important to ensure stability of the falls.

I saw something on T.V. the other day and I thought you might know where I can buy it. The best way to describe it is it looks like a big (about 18 inches wide) harmonica. A single hose connection goes in the back and water comes out multiple holes in the front. Appreciate any help - thanks.

Pondlady sez:
I have never heard of it, let alone seen it. It sounds like a simple manifold and would be easy to build yourself. I have had some experience with 'prefab' waterfalls and pipes or fountain heads with holes in them and very often the holes will clog up. Pretty soon, only one hole is left unclogged and is shooting water out of your pond. It can drain your pond and drive you crazy trying to keep the holes clear.

How to build a waterfall



No, not this one, a waterfall for your pond.

When building a waterfall, stacking the rocks with spaces between them makes the falls louder. There is a echo effect. If it's done properly, waterfall noise can wake up the neighbors. Just be careful that the water coming over the falls ends up in the pond, not on the ground or you could pump your pond dry in a few hours. Most of the dangerous drops in water level are caused by waterfalls where rocks have been placed improperly or have shifted.
