Melville Water lies between Point Resolution and
Point Walter to the west,
Point Heathcote at the mouth of the
Canning River to the south-east, and the
Narrows Bridge where it meets
Perth Water to the north-east. In that space it has marine parks (Swan Estuary marine park in Lucky Bay and Alfred Cove), water ski areas (Waylen Bay, and Point Walter) as well as the Narrows Personal Water Craft Freestyle Area. The main ferry and
tour boat route passes through the centre of the open water in the centre of the river. ==Swan Estuary Marine Park==
