Pond Waterfall ConstructionThe big idea with any pond waterfall construction is simple. All you're doing is creating a chute, typically out of pond liner, to contain and direct the water. Within the chute you're positioning stones in whatever visually pleasing arrangement you like. That's all there is to it really. The rest of pond water construction is merely details. And digging.
Even if you've got a fairly level pond location, you might place the falls six to eight feet from the pond to create a short stream running down to the pond.
You really want to direct the water over the stones not underneath them for the best sparkling visual effect. To accomplish this, once satisfied with the layout, seal some of the rocks to the liner using (black) expanding foam sealant. (How's that for a little known pond waterfall construction tip?)
Make use of larger rocks along the edges to frame your falls and help contain your water course. Then soften those edges and give a natural look and feel to your design using a mix of perennial flowers, low growing shrubs and various ground covers.
If your waterfall doesn't remind disappointed visitors of Niagara Falls it could be because it's too wide or your pump too small.
Finally, and maybe most important, don't worry if you don't get the layout right the first time. Pond waterfall construction is about going with the flow. <groan> Flexibility. And adapting to what you learn once you get into it. Don't be surprised if you have to tear it apart a couple of times until you, like Goldilocks, get it just right.
