Description
The Aquascape 77023 Waterfall Spillway is a compact 12-inch wide spillway unit rated for flow rates up to 4,000 GPH. Internal baffles distribute incoming water evenly across the full 12-inch lip for a smooth, consistent sheet-style waterfall without channeling or surging. Measuring 10.5” × 14” × 5”, it is proportionally smaller than the 22-inch companion (77000) and fits naturally into tighter landscape spaces, narrow stream beds, and smaller pondless waterfall installations.
Connect pump discharge to the rear-mounted 2” bulkhead inlet using either the included 2” PVC slip fitting or the included 1.5” barbed hose fitting. Rock, gravel, and soil can be placed directly on top for complete camouflage. Can be built into hardscape walls for a clean formal sheet waterfall. Backed by a Limited Lifetime Warranty.

Frequently Asked Questions
What is the maximum flow rate for the Aquascape 12" Waterfall Spillway?
The Aquascape 77023 Waterfall Spillway handles flow rates up to 4,000 GPH (15,000 LPH). This makes it ideal for:
- Small to medium pondless waterfall systems
- Streams and waterfalls powered by pumps in the 1,500–4,000 GPH range
- Secondary waterfalls on existing ponds
For larger waterfall volumes (4,000–7,500 GPH), step up to the Aquascape 22” spillway (SKU 77000). Or pair two 77023 units side-by-side for a 24” wide waterfall at up to 4,000 GPH per unit.
How do the internal baffles improve the appearance of the waterfall?
The strategically positioned internal barriers inside the spillway body diffuse high-velocity water entering from the rear inlet, slowing it down and redistributing it evenly across the full 12-inch spillway lip. Without baffles, the incoming flow creates a turbulent central surge with slower water at the edges, producing an uneven waterfall. The baffles produce a level, consistent water sheet across the entire lip — the defining visual characteristic of a professional spillway installation.
What size plumbing is required for the Aquascape 77023?
The 77023 has a rear-mounted pre-installed 2” bulkhead. Two fitting options are included:
- 2” PVC slip fitting — for solvent-welded rigid PVC pipe connection
- 1.5” barbed hose fitting — for flexible kink-free tubing connection
Both fittings attach to the same rear bulkhead. Choose the fitting that matches your plumbing run. Note: the inlet is at the rear of the unit — plan your plumbing run to approach from behind.
Can this spillway be used in a Pondless Waterfall system?
Yes. The 77023 is designed as the starting point for pondless disappearing waterfall systems where biological filters are not required. The pump discharge pipe runs from a buried reservoir basin up to the rear of the spillway. Cover the spillway with boulders, gravel, and plant material — the durable ribbed body supports the full weight of large rocks — for a completely hidden, natural-looking waterfall head.
How durable is the spillway body for heavy rock placement?
The 77023 is molded from high-quality impact-resistant plastic with structural ribbing that provides compressive strength for direct placement of boulders, gravel, and soil on top. This allows the entire unit to be buried beneath heavy rock with only the 12-inch spillway lip exposed for a completely naturalistic waterfall appearance. The ribbing also prevents body flex under hydrostatic pressure, maintaining a level spillway lip for consistent water sheet distribution over time.
Is maintenance required for the 12" Waterfall Spillway?
The 77023 contains no filter media and requires virtually no routine maintenance. Occasionally check that no large debris (leaves, twigs) has accumulated inside the unit that might disrupt the internal baffles. If your installation includes upstream pre-filtration (skimmer or pump vault with a debris screen), debris entry into the spillway body will be minimal. The injection-molded plastic body does not rust, corrode, or degrade from UV exposure over time.
