Limerick Dock is a designated transitional waterbody situated within the tidal reaches of the Shannon Estuary at Limerick City. It encompasses the Ted Russell Dock, approach channels, and the surrounding estuarine waters where the River Shannon meets the sea. The area is characterized by its industrial and maritime heritage, serving as a working port while also offering urban angling opportunities. The underlying geology is Visean Limestone, which forms the foundation of King's Island and the dock area.
