First Spill of Grahamstown Dam Labyrinth

Grahamstown Dam, Hunter Water's major water supply storage, spilled on Anzac Day 2008. This was the first time that the dam had spilled since upgrade works to increase storage volumes were completed in 2005.

The award winning labyrinth spillway, located off the Pacific Highway north of Raymond Terrace, has enabled storage volumes to increase from 130,000 million litres to 190,000 million litres.
