About

Spillways and Waterfall Blades for Ponds and Water Features Spillways create a clean, uniform sheet of water that adds elegant movement and soothing sound to any pond or water feature. Play It Koi carries a variety of spillway styles including stainless steel waterfall blades, acrylic spillways, lighted spillway boxes, and natural-look waterfall weirs. Unlike naturalistic rock waterfalls, spillways deliver a modern, architectural aesthetic that complements contemporary landscape designs, pool surrounds, and formal garden settings. Types of Spillways Stainless steel waterfall blades produce a clear, glass-like sheet of water from a narrow lip. They mount flush to retaining walls, raised pond edges, or purpose-built columns. Wider blades create a dramatic curtain effect, while narrow blades offer a more subtle accent. Acrylic and polycarbonate spillways allow water to flow over a transparent surface for a floating-water illusion. Pondless spillway setups recirculate water from a hidden basin, making them ideal for spaces where a full pond is not practical. Spillway Installation Most spillways mount into a wall or raised edge using a built-in flange and waterproof sealant. The supply line connects to a dedicated pond pump sized to deliver the flow rate needed for an unbroken water sheet. As a general rule, spillways require 100 to 150 GPH per inch of blade width for a solid curtain effect. Under-pumping creates gaps in the water sheet, while over-pumping causes splashing beyond the catch basin. Seal the connection point with fish-safe pond sealant to prevent leaks behind the wall. Lighted Spillways LED-equipped spillways illuminate the water sheet from behind or below, creating a stunning glowing curtain effect after dark. Color-changing models allow seasonal or mood-based lighting adjustments. Pond lighting paired with a spillway is one of the most visually impactful combinations available for water feature design, turning a daytime accent into a nighttime showpiece.
