Access API 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.

Export Data Greater Sydney Declared Catchment, Water Supply System and Special & Controlled AreasThe declared Sydney catchment area is defined in Clause 17 of Schedule 2 of the Water NSW Act 2014. The declared Sydney catchment area is comprised of the inner catchment area and the outer catchment area. The inner catchment area is the area of land within the Special Areas (Warragamba, Metropolitan, Woronora, Blue Mountains ( Blackheath, Katoomba and Woodford), Shoalhaven, Fitzroy Falls and Wingecarribee) and the hydrological catchment of the Prospect Reservoir. The outer catchment is the area of land within the hydrological catchments of the Warragamba River and its tributaries which drain to Lake Burragorang; the Shoalhaven River and its tributaries which drain to Lake Yarrunga; and Greaves, Whipcord, Woodford and Cascades Creeks, but excluding the inner catchment area described above.

For the purposes of groundwater resource management, the state of Western Australia is divided into groundwater areas proclaimed under the Rights in Water and Irrigation Act 1914. These groundwater areas are further subdivided into groundwater subareas. The subareas are not proclaimed, but are administrative boundaries used to manage the abstraction and licensing of groundwater resources.

Surface Water subareas stored in WRIMS (Water Resource Information Management System). Surface Water Allocation Subareas for Western Australia were derived in consultation with the regional offices, and geometry is based on hydrographic catchments. Regional Department of Water and Environmental Regulation officers identified areas of similar management requirements to define boundaries or aggregations of hydrographic subcatchments. Regions with notable management concerns both currently and possibly in the future were identified to become management subareas. Allocation subareas will be used in the calculation of sustainable yields, flow rates and ultimately these calculations will be available for water allocation and natural resource management decisions. In addition, native vegetation clearing values have been calculated for each of the subareas located within the extent of the South-West region of Western Australia, for input into the allocation process. The Surface Water subarea data was developed in order to give a clear understanding of surface water availability and to provide management tools to make good water allocation and natural resources management decisions.
