The Metedeconk River of southeastern New Jersey flows from its North Branch (20 miles/32 km long) and its South Branch (15 miles/24 km long) to their confluence at Forge Pond, where the river then widens (up to just over 1 mile/1.6 km) and flows southeast for 6 miles/9.7 km into the Barnegat Bay. It contains both fresh and salt-water portions. Like many area streets, waterways and towns, Metedeconk is the original word or phrase used by the pre-European peoples of the area, the Lenape.
At its most eastern face the river meets Island Beach, a populated but narrow strip (less than 1 mile (1.6 km wide) of New Jersey separating the Metedeconk from a direct connection with the Atlantic Ocean. Here, the river joins the Barnegat Bay to the south and the narrow, man-made Point Pleasant Canal to the north. This canal provides a convenient connection to the Manasquan River, which would otherwise be completely separated from the Metedeconk by about 3 miles (4.8 km) of land. The Manasquan River is directly connected to the Atlantic Ocean, as is Barnegat Bay.
