Part 3 Outcomes for sustainable management of water

9Outcomes for water in plan area

Water is to be allocated and sustainably managed in a way that—
(a)recognises the natural state of watercourses, lakes and springs has changed because of water infrastructure, flow supplementation and the taking of water; and
(b)seeks to achieve a balance in the following outcomes—
(i)the general outcomes mentioned in section 10;
(ii)the ecological outcomes mentioned in section 11.

10General outcomes

Each of the following is a general outcome for water in the plan area—
(a)to provide for future water requirements, including the opportunity for additional water to be taken from the plan area;
(b)to provide for the continued use of all existing water entitlements and other authorisations;
(c)to protect the probability of being able to obtain water under a water allocation;
(d)to encourage the efficient use of water;
(e)to protect essential water supplies when water availability is low;
(f)to support natural ecosystems by minimising changes to natural flow regimes;
(g)to protect, or minimise the impact of the taking of water on, ecological assets and ecosystem structures and processes;
(h)to allow water-related cultural use of the plan area by the traditional owners of the area;
(i)to provide consistency between this plan and the SEQ regional plan.

11Ecological outcomes

(1)Particular ecological outcomes for water in the part of the plan area stated for the outcome are as follows—
(a)for Coomera River within the area known as Canungra Land Warfare Centre, including, in particular, Back Creek, and other waters of high ecological value under the Environmental Protection (Water and Wetland Biodiversity) Policy 2019, including, in particular, Tallebudgerra Creek and Currumbin Creek—to minimise changes to the flow regimes of the waters;
(b)for Nerang River upstream of the Hinze Dam and Little Nerang Creek upstream of the Little Nerang Dam—
(i)to minimise changes to river-forming processes; and
(ii)to minimise changes to the flow regime;
(c)for Coomera River estuary—
(i)to minimise changes, as far as practicable, to freshwater flows into the Coomera River estuary; and
(ii)to minimise changes to the freshwater inflows to Coombabah Lake.
(2)Also, an ecological outcome for water in the plan area is to minimise changes, as far as practicable, to the volume and seasonality of freshwater flows into Moreton Bay and the Broadwater.

19Decisions not to increase amount of water taken

(1)The chief executive must not make a decision that would increase the average volume of water available to be taken in the plan area.
(2)Subsection (1) does not apply to a decision—
(a)about unallocated water made under section 23 or 24; or
