The first expandable waterfall spillway on the market! With straight, inward and outward curving sections, you can design a waterfall however you like! In fact, waterfalls up to 34' wide have been built using this system! These Pro-Series waterfall spillways have a plastic grating just below the water level that not only keeps the walls from bowing when buried in the ground, but also allows you to stack 3" - 4" of rock to hide the spillway!

• Durable spillways are constructed to last
• Bolts together for easy assembly
