Situated 2 km north of Donabate, this is a relatively small, narrow estuary separated from the sea by a sand/shingle-bar and divided by the Dublin-Belfast railway line. The estuary drains almost completely at low tide, exposing extensive mudflats with some saltmarsh. The largest municipal dump in Ireland is situated on the north-east shore of the site.
This is an important site for wintering waterfowl. Additional species wintering in numbers of national importance include Tadorna tadorna (827 birds, 1996), Anas crecca (677 birds, 1995), Pluvialis apricaria (4,000 birds, 1996), Vanellus vanellus (7,735 birds, 1996) and Tringa totanus (861 birds, 1996).
