How to Disguise a Waterfall Spillway

Measure the size of the waterfall spillway structure's top opening, noting length and width. Also measure the depth of the spillway if the structure's side is visible from the front of the waterfall. Write down these dimensions on paper.

Find a large, flat stepping stone that is larger in length and width than the spillway's top. Use a tape measure and consult your piece of paper to choose a stepping stone. Match the color or texture of this flat stepping stone with the rocks already used in the waterfall feature. Also look for smaller rocks that are of an appropriate size to hide the front of the spillway if needed.

Brush off any clinging cobwebs or soil from the bottom of the selected flat stepping stone. Place it atop the spillway structure to cover it, but still allow water to pour out from the chute to feed the waterfall.

Tuck additional rocks around the base of the spillway structure's front to hide it from view.

Plant foliage plants at the edge of the waterfall in soil so their leaves jut out to partially hide the rocks surrounding the spillway structure. Alternatively, position plants still in containers among rocks to help soften the look of the waterfall and rocks it contains.

Add extra rocks around the plants and the spillway structure to fill in any noticeable gaps or unwanted views.
