Menindee’s 250 GL trigger restores targeted water restrictions
Read the analysis
NSW has reinstated restrictions on specified northern Murray–Darling water take as active upper Menindee storage falls below 250 GL. The October order protects downstream needs through licence-specific controls, with exemptions and measured-flow conditions rather than a blanket pumping ban.
Targeted restrictions on water take in the northern Murray–Darling Basin returned from 1 October 2026 as active upper Menindee Lakes storage fell below 250 gigalitres. The NSW order directs specified licence holders to leave water in the system to support downstream needs and river connectivity.
The trigger concerns water that can be released
Menindee water restrictions use the active volume in Lakes Tandure, Wetherell, Pamamaroo and Copi Hollow. Dead storage is excluded. This makes the trigger different from a headline total for the whole lake system: the relevant quantity is water capable of being released from the upper lakes.
The order, gazetted on 25 September, remains in force until 30 June 2027 unless amended or repealed. Its restrictions are conditional on the storage trigger and the detailed schedule. The legal duration does not mean that every affected licence is prohibited from taking water continuously until that date.
The department links the controls to critical supplies at Menindee and Pooncarie, basic landholder rights and environmental needs during low flows. Protecting water for downstream movement addresses a shortage where the remaining reserve has competing claims. It is a protective intervention, rather than proof that supplies have been secured for a guaranteed period.
Licence categories and flows determine the reach
The schedule specifies relevant floodplain-harvesting, supplementary and unregulated access licences in named sources or management zones. It also includes particular restrictions on overland flow. Basic landholder rights remain outside the specified access-licence prohibitions, and the order sets out other exemptions for particular purposes or works.
Measured high-flow conditions can allow water take that would otherwise be restricted. Those conditions vary by source, licence and gauge; rainfall in the general region is not a substitute for satisfying the stated threshold. The department says the Natural Resources Access Regulator will use officers, satellite imagery and spatial information to check compliance.
The immediate operational distinction is between a system-wide concern and a licence-specific direction. The upper-lake reserve supplies the trigger, but the schedule determines which activities are constrained and when exceptions apply. That combination seeks to preserve downstream water while allowing specified higher-flow opportunities under the order’s conditions.
Take-Out
The restriction depends on releasable upper-lake storage, licence category and applicable flow exemptions; a regional headline alone cannot establish whether a particular water take is prohibited.
Questions and answers
What readers should know
- What storage threshold triggers restrictions?
- Less than 250 GL of releasable water in the upper Menindee Lakes.
- Which lakes form that upper group?
- Tandure, Wetherell, Pamamaroo and Copi Hollow.
- Does the order ban all pumping?
- No. It targets specified licences and activities, with exemptions and flow conditions.
- When does the order expire?
- 30 June 2027, unless it is amended or repealed earlier.
- Can a major rain event automatically lift restrictions?
- No. Relevant measured-flow thresholds and other conditions must be met.
