WaterNSW advised releases from Copeton Dam have decreased to 5,000ML/day.  Copeton Dam remains steady at 99% capacity, with all accounts at their maximum allocation. 

The water releases take 4-5 days before reaching Pallamallawa.

The Gwydir River at Yarraman remains at a minor flood level, with additional inflows below Gravesend combining with spill releases from Copeton Dam.  Keep an eye on the BOM weather warnings for any flood warning updates.

From 1 December 2021, along with the last stage of new metering requirements for the Valley the NSW Government also kicks of new reporting needs.

These are for water users that use their work for multiple purposes and they require you to report the split in your licensed water and Basic Landholder Rights use, to ensure water is not deducted off your license.  Without reporting, all the water use measured will be considered licensed.  The rules also include self meter reads for those water users who do not have telemetry.  The rules are explained here .

The rules are rather Draconian for water users that do not use water for irrigation but have a licensed attached to the work and therefore have the potential to irrigate, as you need to add up the water used each month and report it as BLR.  We would encourage you to write with your first report, complaining about these requirements as you are not an active irrigator but want to use the work for Basic Landholder Rights.  We did provide a submission at the time which was clearly ignored. 

The attached approved form, which also has to be used is provided in the below link.

WaterNSW advised that releases from Copeton Dam were increased to 16,000 megalitres per day and again, to 20,000 megalitres per day to account for recent rainfall upstream at Bundarra and with the current forecast.  

These flows are now meeting with existing inflows and the the flows are larger and more sustained than the stream capacity of any system, downstream (West) of Moree township being: the Lower Gwydir and Gingham, Mehi, Moomin and the Carole and Gil Gil systems. Flooding in low lying areas or known chokes in these systems is likely as a result of these flows and that is before any further inflows.  Flooding is already occurring along the Lower Gwydir, Gingham and Carole systems from earlier this week and local inflows.  

For a comparison of past floods, their heights and flow rates please visit our webpage History of Flooding, whcih was updated to reflect the flood already this week.

For the first time since July 2012, Copeton Dam has reached 99% and WaterNSW have had to release water to make airspace for inflows, which are the tail of the current event at Bundarra on the Gwydir River.  This is only the fifth time since construction the dam has reached this level. 

Releases at this stage are 5,000 megalitres/day for the next few days, depending on the weather. WaterNSW will aim to maintain Copeton at 100%, no more or no less.  These flows are well within the operational capacity of WaterNSW downstream near Moree. 

All accounts associated with Copeton Dam are now full, with some unallocated water. 

Releases are considered unregulated events and shared accordingly.

The Bureau of Meteorology have issued a moderate flood warning again for the Gwydir Valley, with Major flooding expected at Yarraman of 7m by Tuesday. 

Follow the BOM Flood Warning updates here.

Follow and check in with river heights along the river via the BOM river network here.  WaterNSW systems (WaterInsights - the preferred platform, WaterLive app and Realtime data) are overloaded and at times have delayed data or cannot be displayed.

Fast Facts |

The Gwydir Valley is a distributary river system, which spreads our rivers and creeks across the Gwydir Floodplain which acts as a large inland delta. Our rivers spill out naturally to these floodplains when they are full and spilling.  Not every flood is the same, they range in magnitude of height and duration and can occur from locally generated rain or from rainfall further upstream of the catchment. 
Recent flood warnings in December 2020 were predicted because of upstream rainfall and inflows.  This was a short, sharp and small flow which has created limited flooding.  For example, the height at Pallamallawa was half of that experienced in 2011 and 2012 when the entire north-west was in flood. This flow also didn't contain a lot of water but its peak flow rate at Pallamallawa of 33,000 ML/day was still higher than the operating capacity of the regulator and cannot be managed.  Rather this water flows naturally, unmanaged by WaterNSW to the watercourse the lowest point of our inland delta and towards the Gwydir Wetlands.

Metering |

DPIEW have updated the Metering Guidance Tool with a number of new questions to better guide you through the metering requirements.  We recommend everyone step through this process to help them work out whether they need to call a Duly Qualified Person or not about needing a meter.

Have your work approval and licence conditions on hand - you will need them to complete many of the questions.  Remember to watch our videos via Vimeo  which step through how to find these numbers and the information your need.

Copeton Dam is currently at 95% capacity with inflows still occurring from recent rainfall above the Dam - the dam storage levels can be checked via WaterInsights. Copeton only needs to get to 96% capacity before all licences have full allocations, meaning that at 100% capacity there is unallocated water that sits until there is account space for it to be allocated.

However, for context, Copeton Dam has only reached 99% capacity for an extended period on four occasions since it was finished full construction in 1976. Being 1978, in 1984, 1998 and most recently in 2012.   

Please note, WaterNSW are not making airspace releases from Copeton Dam at this stage but this is occuring for Keepit Dam in the Namoi Valley.

With minor flooding in the Gwydir Valley, WaterNSW has issued an update to the 9 November supplementary announcement, today the 12 November 2021, increasing access to 100% of allocation for those interested with updated pumping volumes provided.

Anyone who did not participate in the EOI earlier this week and would now like to participate must call WaterNSW to discuss, do not just put in a water order you must email

Reminder to place water orders via iWas or using the form and emailing

The BOM have revised the Flood Warning for the Gwydir Valley down to minor via their updates here.  

Whilst the flood level has reduced.  The flow rate in the Gwydir River is currently above the safe operating level of the infrastructure at Tareelaroi Weir - this means that the gates are fully lifted, allowing the river to flow in its natural direction which temporarily limits the ability for WaterNSW to direct flows down the Mehi River. That is why there has been a drop in the Mehi River below the regulator late yesterday as the gates were required to be opened, the levels will rise with further water flows and/or when WaterNSW can close some of the gates on the regulator. 

River heights can be viewed via WaterInisghts and selecting the Gwydir Regulated River, below find your location.

Contact WaterNSW if you have any further questions.

News |

The Bureau of Meteorology have issues a flood warning for moderate to major flooding of the Gwydir and Mehi Rivers, for the weekend.

The rainfall activity is storm based and very difficult to predict but its important to keep watch of updates vis the SES or the BOM websites.  

For an assessment of past floods and their heights including the most recent events in December 2020 and March 2021, visit our webpage History of Flooding. We will update this page with any new flood predictions if they occur.

Stay safe.
