Description: All features have been included from the Surface Hydrology data capture. This layer is only for labelling. 250K Specification Description - Dam Wall - A barrier of earth and rock, concrete or masonry constructed to form a reservoir for water storage purposes or to raise the water level.

Description: All features have been included from the Surface Hydrology data capture. This layer is only for labelling. 250K Specification Description - Watercourse - A natural channel along which water may flow from time to time. Connector - An artificial line used to connect linear Hydrographic features across a defined area feature to allow network analysis of riverine networks. Connections across area features will be defined by the visual interpretation of imagery to achieve logical water flow patterns based on subtle variations in soil, vegetation and noticeable landform slope. (Source - http://www.ga.gov.au/mapspecs/topographic/v6/appendixA_files/Drainage.html). NOTE - This layer only displays between the 1:10,000,000 and 1:5,050,000 scale to avoid clutter. Refer to other Watercourses layers at different scales for the National Map.

Description: These data are best suited to graphical applications. These data may vary greatly in quality depending on the method of capture and digitising specifications in place at the time of capture. All features have been included from the 250K data capture. 250K Specification Description - Breakwater - A solid structure to break the force of the waves, sometimes detached from the coast, protecting a harbour or anchorage. Jetty - A structure projecting into a body of water for use as a promenade or as a platform alongside which vessels may be secured for loading and unloading passengers and cargo. Sea Wall - A solid structure usually of concrete masonry or earth, built to prevent erosion or encroachment by the sea. Wharf Line - A structure built along the shoreline to provide for the berthing (or mooring) of vessels. In large commercial ports it may be associated with warehouses and storage facilities for shipping containers. (Source - http://www.ga.gov.au/mapspecs/topographic/v6/appendixA_files/Marine.html)
Description: All features have been included from the Surface Hydrology data capture. 250K Specification Description - Canal Line - An artificial open channel which provides the supply, distribution or removal of water for irrigation purposes, or for a significant infrastructure function (such as salt interception, land reclamation, or drainage between water features for environmental management purposes).

Description: All features have been included from the Surface Hydrology data capture. 250K Specification Description - Rapid Line - An area of broken, fast flowing water in a watercourse, where the slope of the bed increases (but without a prominent break of slope which might result in a waterfall), or where a gently dipping bar of harder rock outcrops.

Description: All features have been included from the Surface Hydrology data capture. 250K Specification Description - Spillway - A channel or duct formed around the side of a reservoir past the end of the dam wall, to convey flood discharge from the watercourse above the reservoir into the watercourse below the dam wall.
