1.3.3.2 Gaps

Data for surface water and groundwater entitlements in the far east of the PAE (outside the bioregion assessment boundary, but within the PAE) was extracted from NSW Office of Water at a later time. This is because the original dataset did not include this area. Groundwater entitlements were extracted from the NSW Office of Water licensing system in May 2014. Surface water entitlements were extracted from the NSW Office of Water licensing system in November 2014. Original extracts from NSW Office of Water licensing system were obtained in November 2013. The Namoi region is a fully capped groundwater and surface water system so therefore the total number/ volume of entitlements is not expected to be significantly different, with the changes immaterial. Therefore, it is not expected to be an issue that extracts from the Water licensing system have been taken at different dates.

Further economic assets were identified during the Gunnedah workshop including surface water storages used for floodplain harvesting. Floodplain harvesting water storages are in the process of being digitised by the NSW Office of Water and were not available for inclusion in the water‑dependent asset register at this time. The data in the Surface Water Access Entitlements received from the NSW Office of Water do not include details of the river reach where the offtake was located; instead data included the Water Source and Water Management Zone that are associated with the WSP. A water source can be any set of rivers, aquifers or lakes and the like, which are defined by a gazetted WSP to be a water source. Therefore when the elements are aggregated into the asset, water licences are grouped together across the water source which is a large polygon. This will need to be taken into account when assigning receptor locations as the water source may include multiple river reaches and potentially multiple river branches.
