Site description A rather narrow estuary, which widens at its mouth and comprises intertidal mudflat and saltmarsh habitats. It is situated on the east coast, at the border between Counties Louth and Meath and is the port for the town of Drogheda. The estuary has been modified by the construction of training walls on either side, to facilitate deep water access to the port.

Key Biodiversity An important site for wintering waterfowl; additional species that winter in numbers of national importance include Pluvialis apricaria (6,000 birds, 1995), Pluvialis squatarola (255 birds, 1996), Vanellus vanellus (7,500 birds, 1996), Calidris alba (163 birds, 1996), Limosa limosa (287 birds, 1996) and Arenaria interpres (444 birds, 1995).
