During 2017 to 2020, large areas of NSW faced severe water shortages. Between January 2017 and December 2019, NSW temperatures were the warmest and rainfall was the lowest on record. Find out more about our drought recovery actions.
The NSW Government has developed an extreme events policy (PDF, 718.67 KB) and incident response guides for all surface and groundwaters in the Murray Darling Basin. The guides are included in each of the water resource plans as they are placed on public exhibition.
Water availability during high flows or flood
During periods of high flow, water is shared in accordance with the water sharing plan.
In the case of very high and flood flows, WaterNSW works with the State Emergency Service to manage flows and provide timely information to affected communities.
Monitoring water during flood
Collecting and sharing data plays an important role in day-to-day water management activities across the state. During flood events this role becomes even more critical for flood forecasting and flood management.
WaterNSW manages over 700 telemetered water monitoring sites. This network is a critical element in decision making by key agencies such as Bureau of Meteorology and the State Emergency Services.
