Catchment Boundaries of NSW

This data set shows the administrative catchment boundaries as defined under the NSW 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.
