This dive site, East Dam, is situated approximately 18km from Sai Kung Public Pier, offering a unique underwater landscape formed by the High Island Reservoir's eastern seawall. Over 2500 'double-T' or anchor-shaped concrete blocks create a fascinating artificial reef, providing intricate structures for exploration and navigation. While part of a reservoir system, this specific dam faces the open sea, allowing for a distinct marine diving experience.
The site is home to diverse marine life, making it appealing for various interests. Macro enthusiasts can spot nudibranchs and lobsters among the concrete formations. Divers might also encounter schooling fish, with groups of barracudas sometimes weaving through the concrete structures, adding an exciting element to the dive.
With a maximum depth of 10 meters and an average depth of 5 meters, East Dam is highly accessible for divers of all levels, including beginners and freedivers. It's an excellent location for macro photography and exploring unique artificial reef habitats. Best times to visit would typically align with calmer sea conditions for optimal boat access and better visibility, though specific seasonal highlights for marine life are not detailed.
