(Source - http://www.ga.gov.au/mapspecs/topographic/v6/appendixA_files/Drainage.html). NOTE - This layer only displays between 1:5,050,000 to 1:300,000 scales to avoid clutter at the national scale (approx 1:36,000,000). Refer to other Watercourses layers at different scales for the National Map.

Description: All features have been included from the Surface Hydrology data capture. 250K Specification Description - Swamp - Land which is so saturated with water that it is not suitable for agricultural or pastoral use and presents a barrier to free passage.

Description: All features have been included from the Surface Hydrology data capture. 250K Specification Description - Marine Swamp - That low lying part of the backshore area of tidal waters, usually immediately behind saline coastal flat, which maintains a high salt water content, and is covered with characteristic thick grasses and reed growths.

Description: All features have been included from the Surface Hydrology data capture. 250K Specification Description - Land Subject to Inundation - Low lying land usually adjacent to lakes or watercourses, which is regularly covered with flood water for short periods.

Description: All features have been included from the Surface Hydrology data capture. 250K Specification Description - Saline Coastal Flat - That nearly level tract of land between mean high water and the line of the highest astronomical tide.
