Catchment Boundaries of New South Wales

This data set shows the administrative catchment boundaries as defined under the NSW Soil Conservation Act. Boundaries east of the Lachlan were gazetted around 1986. Western boundaries have not been gazetted and, hence, have the label (Not notified) attached to them. The Western catchment boundaries are more appropriately described as sub-catchments as they do not straddle the Darling River. The data set is taken from the NSW broad scale topographic base developed by CaLM (LIC) in map form in the Atlas of New South Wales. The data has been digitised from 1:100 000 base maps by the Soil Conservation Service of New South Wales.

本数据集展示了依据新南威尔士州（New South Wales，简称NSW）《土壤保护法》划定的行政集水区边界。拉克伦河以东的集水区边界于1986年左右完成官方公告备案；西部边界尚未完成公告备案，因此标注为‘（未通报）’。由于西部集水区边界未跨越达令河（Darling River），其更适宜被称为子集水区。本数据集源自新南威尔士州《新南威尔士州地图集》中由CaLM（LIC）编制的大比例尺地形底图，数据由新南威尔士州土壤保护局从1:10万比例尺底图数字化而来。
