Summary

Description

The Drainage basin sub-area polygon coverage depicts a subdivision of the major drainage basins (catchment) in Queensland. Its original purpose was to implant some location identifier into the numbering system of bores and gauging stations. For example all bore numbers were prefixed with a four-digit number. The first three were used to locate the bore into a specific major river basin. The fourth digit was used to locate the bore into a subdivision of that major river basin as shown in the Sub-Basin Areas - Queensland coverage. This coverage is now only used as a means of numbering bores and gauging stations. Its capture scale is 1:100 000.Legislation: Water Act 2000, Division
