Mangrove Creek Dam, Embankment dam in New South Wales, Australia.
Mangrove Creek Dam is an embankment dam in New South Wales that stores water for the Central Coast region. The structure is built from locally sourced materials including sandstone and basalt extracted from nearby quarries.
Construction of this water facility began in 1978 and was completed in 1982. It was developed to secure the region's water supply for the long term.
The dam structure represents Australian engineering capabilities, incorporating local materials including sandstone, siltstone, and processed basalt from nearby quarries.
The site can be reached via Williams Road or Kyola Road from George Downes Drive near Kulnura. As it is located in a rural area, it is wise to check access conditions before visiting.
The facility remained not fully filled for 40 years until July 2022, when heavy rains caused it to overflow for the first time. This event showed how rarely intense rainfall occurs in the region.
