NSW Water Dashboards-Tracking Groundwater Extraction
Tracking groundwater extraction against extraction limits: How extractions are tracking against extraction limits in inland groundwater sources. How and why we track groundwater extraction: The amount of groundwater that can be extracted from a groundwater source is limited. While the amount extracted by all water users varies each year, on average it cannot exceed the extraction limits (i.e. the long-term average annual extraction limit or the Sustainable Diversion Limit). Before July each year, the department assesses if average extraction over the previous five years has exceeded the long-term average annual extraction limit plus a buffer (called the compliance trigger). For each inland groundwater source, the dashboard shows for the current water year: volume that if extracted will reach the compliance trigger (in ML, calculated annually) volume remaining to be extracted before reaching the compliance trigger (in ML, calculated throughout the year) the likelihood that access to groundwater may be reduced in the next water year.
