Estuary Management

Byron Shire Estuaries

An estuary is a partly enclosed coastal body of water with one or more rivers or streams flowing into it, and with a free connection to the open sea. Estuaries, located at the boundary of marine and freshwater ecosystems, form a transition zone between river environments and ocean environments and are subject to both marine influences, such as tides, waves, and the influx of saline water; and riverine influences, such as flows of fresh water and sediment. The inflow of both seawater and freshwater provides high levels of nutrients to the water column and bottom sediments, making estuaries among the most productive natural habitats in the world.

There are two estuarine systems in the Byron Shire: Belongil Estuary and Brunswick Estuary.
