Departments and roles in water management

Demonstrate how water resources will be shared and managed

to be consistent with the Murray-Darling Basin Plan.

Set out the requirements for annual limits on water take,

environmental water and managing water during extreme events.

Provide strategies to protect water quality and manage risks.

Set out the arrangements for measuring ‘take’ and monitoring the

resource.

Water resource plan – a Basin Plan requirement

The water sharing

plan forms part of

the WRP. Relevant

parts of a water

sharing plan are

assessed by the

MDBA and

accredited by the

Commonwealth

Minister.

NSW Water Management Act

2000

Water sharing plans

Specify the rules for sharing

water to maintain the health,

sustainability and productivity of

surface water and groundwater

sources across all of NSW.

Commonwealth Water Act 2007

Murray–Darling Basin Plan 2012

Water resource plans

Specify the rules for diverting water

within specified areas of the

Murray–Darling Basin.

Elements include:

• Compliance with the sustainable

diversion limits and water trade

rules

• Protection of water for the

environment

• Water quality and salinity

management and objectives

• Aboriginal values and uses

• Measuring and monitoring

• Arrangements for managing

extreme events

Water Sharing Plans remain the primary

statutory instruments for water sharing in

NSW

Barwon-Darling Water Sharing Plan

Barwon-Darling water source

Removal of groundwater sources and associated rules

Objectives, strategies and performance indicators revised

Establish a second extraction limit (sustainable diversion limit specified

Changes to A Class flow thresholds

Implementation of Individual Daily Extraction Limits

Active management of environmental water

Proposed changes to the water sharing plan

Changes in A class thresholds

• Revision of the A-Class Flow Thresholds, changes recommended by

NRC and Vertessy Report

• Proposed A Class thresholds based on multiple sources of information

• Protect low flows plus 10% of the base flow range

• No change to thresholds at Walgett Weir and Mogil Mogil

Proposed A class flow thresholds

Removal of imminent flows

• Part of the NSW Government response to NRC review

• Current rules allow A and B class licences to request access to low

flows and cease to flow when flows are imminent

• NRC found current rules unlikely to meet requirement for Ministerial

approval:

• granting access is likely to cause unacceptable downstream or

local impacts on the environment or on other users

Removal of imminent flows

Protection of the resumption of flow

Protecting the resumption of flows

Multi-sectional rule design

• Cultural benefits to Aboriginal communities who have an association with the river. It is

important for regional community well-being.

• Local economies often suffer due to the limited recreational and social opportunities during

dry periods.

• Local communities who rely on this water for human needs and for their stock.

• Environmental benefits include protecting pool habitats, maintaining water quality, and

wetting of the channel (especially if there is a larger flow following).

Benefits

Individual Daily Extraction Limits

IDELs will limit the volume of water that can be taken from the river every day so that there is the

potential for water to flow downstream to achieve local and downstream benefits, including for the

environment.

Purpose

The maximum total extraction per day (per licence class) will be the sum volume of all authorised pump

capacities or agreed pumping rates in place in October 2012, just prior to the commencement of the

2012 WSP.

Total daily extraction pool

A Class B Class C Class

513 ML/day 10,962ML/day 8,193ML/day

A water access licence has a share component and an extraction component.

Individual Daily Extraction Limits (IDEL)

Share pool Extraction pool

The IDEL has three parts;

- location of management zone,

- the daily flow share,

- and an announcement

IDELs by River Section

River Section 4 A Class 1,403 72.7

B Class 17,031 1,403.0

C Class 5,537.2 991.7

Distribution:

• IDELs will be distributed based on the licence holders’ share component and will be in the same proportion as

their share of the total of all shares, within each licence class.

• Expressed as a ‘Daily Flow Share’ where 1 DFS = 1 ML unless a lower amount is announced

Trade:

• Permanent trade within river section will be allowed

• No temporary trade is proposed at this stage

Key dates:

• IDELs will be distributed based on the licensing information available as at the first day of public exhibition of

the draft water sharing plan (26 September 2019)

• IDELs are to be effective from the beginning of the next water accounting year (1 July 2020) pending

commencement of the proposed plan amendments

IDEL details

Active management of environmental water

What is active management

• Current unregulated water sharing plans do not protect held environmental water used in-stream from extraction

The problem

• Increased level of management in unregulated rivers

• Involves forecasting flows and estimating volumes arising from different sources and announcing access

Active management – the solution

• Protects water used in-stream for environmental purposes

• Reduces the need for temporary water restrictions

• Clearer for licence holders and public to know when water can and cannot be taken

The benefits

• from an upstream water source

already protected by the

unregulated water sharing plan

• assessed as additional to the

inflows considered when the

Barwon-Darling water sharing plan

commenced

Planned Environmental

Water

• HEW from northern NSW regulated

water sources and Queensland

storages in the Border Rivers

• Unregulated HEW in an active

management area

A method for determining the volume of

HEW arriving at the NSW-Queensland

border must be agreed by NSW before

HEW originating in Queensland will be

active managed in NSW water.

Held Environmental Water

(HEW)

Water to be protected from extraction

Adjusting access – the concept

In-stream use of unregulated HEW

An environmental water holder will be allocated a volume that they can used on a given day in the same manner as other licence holders

The environmental water holder will need to advise what volume they want to leave in-stream for environmental purposes. They can leave all or some of the water available to them in-stream.

The volume left in-stream will be debited from the HEW allocation account.

The volume debited will be protected from extraction through downstream management zones.

The Procedures Manual will outline:

• The type of water to be protected from

extraction

• How losses are estimated and shared

and operational uncertainty is managed

• How access is determined

• The form and content of

announcements

• The process for accounting for in-

stream use of unregulated HEW

• Must be published on Department’s

website

• Feedback is welcome on Active

Management in Unregulated Rivers –

Draft policy for public consultation

This policy will guide the development of the

procedures manual

Procedures Manual

In summary - changes are proposed to:

Define active environmental water

Adjust access by the amount necessary to

protect the active environmental water from extraction and announce access

Allow unregulated HEW to be left in-stream

Require publishing of an Active Management

Procedures Manual on the Department’s

website

Public Exhibition period

The Barwon-Darling Watercourse Surface Water Resource Plan is on public exhibition from 26 September to 29 October 2019.
