Text Note field should be added when directed in the Geodatabase Rules or if descriptive information is known about a feature that is not covered by any other item in the feature class and expands on the definition of the feature.

Where a connector joins two canals, or joins a canal to another connector it will have a perenniality of ‘Not Applicable’ and a hierarchy of ‘Not Applicable’. A connector joining a canal to a stream will take the perenniality of the stream. See Section 1 3.11.3  
 

No connectors will be added unless there is a logical basis for, or clear evidence to, confirm that a flow of water links, either:
-disconnected linear features in the drainage feature dataset, through a waterbody or mangrove feature, or
- provides connectivity of a linear feature in the drainage feature dataset through a waterbody feature or mangrove feature to the sea.

Connectors will carry the attributes of the watercourse they represent ie. the classification and perenniality shown in the supplied Water Guide in Appendix D (see Section 1, chapter 3.8.3).

Connectors will be used to extend the stream network to the coastline where applicable.

Connectors will not be shown around both sides of an island. That is, only one main connector will appear, with associated tributary connectors coming in from one or both sides.

Connectors must fall wholly within waterbodies or mangrove except where there is evidence that a loss in hydrological connectivity would occur eg. A connector may be used to duplicate a water pipeline to provide hydrological connectivity. Such a connector may also be used in areas where a watercourse feature flows underground and re-emerges.

The number of vertices used to define connectors should be sufficient only to keep it well within the waterbody area.

Connectors may be used through all waterbodies except Salt Evaporators, Aquaculture Areas and Settling ponds.

A connector may cross a mangrove (without an associated waterbody) when a watercourse enters a mangrove but there is no defined channel to the sea.

It is preferable that the ends of connectors are positioned perfectly over a node or vertice in the underlying waterbodies perimetre, and at worst should fall within 1 metre of the features perimetre line.

Connectors will pass through Reservoirs to connect to the Spillway linear feature.

Text Note field should be added when directed in the Geodatabase Rules or if descriptive information is known about a feature that is not covered by any other item in the feature class and expands on the definition of the feature.

At 1:100 000 size and any other selection criteria apply to all feature occurrences.

At 1:250 000 size and any other selection criteria apply to new feature occurrences. All feature occurrences existing in the TOPO250K NTDB will be retained unless there is clear evidence they no longer exist.

Watercourses shown as double line streams on the latest previous edition map or compilation material at the comparable scale will be shown as watercourse area polygons. Other watercourses will be shown as watercourse area polygons where they are wider than 1 mm at scale and meet the area criteria.

The perenniality and hierarchy of Watercourses will be classified according to Appendix D - Inland water features guide where the watercourse is shown on the guide. This guide has undergone some generalisation. If there is strong evidence on imagery that the main alignment of the stream differs to the guide, then the image position should be given precedence, as long as it does not break the logical drainage attribute connectivity and does not deviate for a significant distance.

Perenniality of watercourses not on the guide will be non-perennial unless there is strong evidence to the contrary. Watercourse not shown on the guide will be classified as minor-non perennial except for tidal watercourses in mangrove. Once a watercourse enters or bounds a mangrove, that watercourse will become perennial and then remains perennial from that point to the shoreline.

A watercourse may be classified on the guide as perennial but shown as an area with one or more channels running down its length. The channels will be coded as perennial watercourse lines and the watercourse areas will be coded as non-perennial watercourse areas. In this situation a channel may at times be in close proximity to or coincident with the waterbody boundary that defines the edge of the watercourse area. Both the linear and area instances will be coded as major. See GEODATA notes for the handling of braided streams.

Braided streams fall into two categories; those that flow within clearly defined primary banks and those that don’t. There is slightly different handling of each category. Section 3 chapter 6.9.4 shows the handling of braided streams lying in primary banks
For braided streams within clearly defined primary banks all channels will carry the name and perenniality of the Watercourse. All channels will have a planimetric accuracy of 9999. For Watercourses with hierarchy major the channel(s) identified in Appendix D will be coded as major. Remaining channels will have a hierarchy of minor. The area between the primary banks will be shown as a watercourse area.

For braided streams not in clearly defined banks, at least one channel will carry the name and perenniality of the watercourse. Other channels that form part of the watercourse should carry the name and perenniality. However, if it is unclear whether the channel is part of the named watercourse it should be left unnamed and follow the rules for watercourses not shown on Appendix D. For Watercourses with hierarchy major a contiguous channel will be coded as major. Where possible this channel will be an identifiable main channel. Where there is no identifiable main channel a channel will be selected which follows the general course of the stream and, where possible, links waterholes. Remaining channels will have a hierarchy of minor  

There is no polygon infill associated with a braided watercourse. Braided streams with a hierarchy of major will have only the channel coded as major shown with symbol 92 (major watercourse).  

Watercourses will have nodes at all intersections.

Watercourses cannot overlap Lake perennial, Flood Irrigation Storage, Town Rural Storage, Watercourse Area Perennial and Canal Area.

There is no polygon infill associated with a braided watercourse. Braided streams with a hierarchy of major will have only the channel coded as major shown with symbol 92 (major watercourse).  

At 1:250 000 the perenniality of single line watercourses will not be represented on the map.
