About Our Waterway

Our local identity is based on the natural resources and ecosystems that define the waterway.  These features include the waterway’s catchment, foreshores, and marine environment.  The D’Entrecasteaux Channel and Huon Estuary are drowned river valleys which became inundated during the last post-glacial rise in sea level.  The D’Entrecasteaux Channel previously formed part of the Derwent River until a rise in sea level of about 60m between 6500 and 13,000 years ago.
