Resource (Boyne River Basin) Plan 2000. 2 Purposes of plan The following are the purposes of this plan— (a) to define the availability of water in the plan area; (b) to provide a framework for sustainably managing water and the taking of water; (c) to identify priorities and mechanisms for dealing with future water requirements; (d) to provide a framework for establishing water allocations; (e) to provide a framework for reversing, where practicable, degradation that has occurred in natural ecosystems, including, for example, stressed rivers. 3 Definitions The dictionary in schedule 4 defines particular words used in this plan. s 4 6 s 6 Water Resource (Boyne River Basin) Plan 2000 PART 2—PLAN AREA AND WATER TO WHICH PLAN APPLIES 4 Plan area This plan applies to the area within the plan area boundary shown on the plan area map in schedule 1.1 5 Water to which plan applies This plan applies to water in a watercourse, lake or spring in the plan area. PART 3—OUTCOMES FOR SUSTAINABLE MANAGEMENT OF WATER 6 General outcomes Water is to be managed and allocated— (a) to ensure a reliable and secure supply of water from Awoonga Dam during the time this plan is in force; and (b) to ensure the supply of regulated water in the area downstream of Awoonga Dam for agriculture and other small scale uses; and (c) to allow water to be taken upstream of Awoonga Dam full supply level or from Awoonga Dam for— (i) agriculture and other small scale uses; and (ii) urban needs; and (d) to protect the probability of being able to obtain water under a water allocation. 1 A copy of the plan area map may be inspected at the department’s offices at the following places— • 41 George Street, Brisbane • 212 Quay Street, Rockhampton. s 7 7 s 7 Water Resource (Boyne River Basin) Plan 2000 7 Ecological outcomes River flows are to be managed— (a) to maintain existing habitats that sustain native plants and animals— (i) associated with watercourses, waterholes and riparian zones upstream of Awoonga Dam full supply level; or (ii) dependant on pool and associated riparian habitat in the freshwater reach downstream of Awoonga Dam; and (b) to provide water for fine sediment removal and long term water quality suitable for— (i) riverine ecosystems upstream of Awoonga Dam full supply level; and (ii) ecosystems downstream of Awoonga Dam; and (c) to allow movement by marine and estuarine fish over or around the weir at Boyne River AMTD 17.2 km; and (d) to provide water to stimulate reproductive processes for estuarine animals downstream of Awoonga Dam; and (e) to provide water for delivery of catchment based nutrients from upstream of Awoonga Dam to the riverine and estuarine reaches downstream of the dam; and (f) to allow river forming flows upstream of Awoonga Dam full supply level and in the riverine and estuarine reaches downstream of the dam; and (g) to allow for an increase in the frequency and duration of marine conditions in the estuarine reach downstream of Awoonga Dam leading to a shift towards plant and animal species that favour or tolerate the increase. s 8 8 s 11 Water Resource (Boyne River Basin) Plan 2000 PART 4—ENVIRONMENTAL FLOW OBJECTIVES, WATER ALLOCATION SECURITY OBJECTIVES AND PERFORMANCE INDICATORS Division 1—Preliminary 8 Calculation of objectives The environmental flow objectives and water allocation security objectives stated in this plan have been calculated using the IQQM computer program. 9 Calculation of performance indicators (1) For the environmental flow and water allocation security objectives, the performance indicators are calculated using the IQQM computer program’s simulation for the period from 1 January 1891 to 31 December 1997 (the “simulation period”). (2) If it is not practicable to use the IQQM computer program to calculate the performance indicators, the indicators may be calculated under an assessment method approved by the chief executive. (3) The chief executive may approve an assessment method for subsection (2) only if the chief executive is satisfied the method will accurately assess the impact of an allocation and management decision or proposal on water entitlements and natural ecosystems. Division 2—Environmental flow objectives and performance indicators 10 Environmental flow objectives The environmental flow objectives for this plan are stated in schedule 2. 11 Performance indicators The performance indicators for the environmental flow objectives are as follows— (a) average summer flow; s 12 9 s 14 Water Resource (Boyne River Basin) Plan 2000 (b) mean annual flow; (c) monthly low flows; (d) number of days of flow to inundate riparian zone; (e) number of river forming flows; (f) number of trigger flows. Division 3—Water allocation security objective and performance indicator 12 Water allocation security objective For water allocations relating to Awoonga Dam, the monthly reliability of supply of water under the allocations during the simulation period must be at least— (a) if the dam’s full supply level is not more than 30 m AHD—99%; or (b) if the full supply level is more than 30 m AHD—100%. 13 Performance indicator The performance indicator for the water allocation security objective is the monthly reliability of supply of water from Awoonga Dam during the simulation period. PART 5—STRATEGIES FOR ACHIEVING OUTCOMES 14 Decisions about allocating water Decisions about the future allocation of water in the plan area must be consistent with— (a) the environmental flow objectives stated in schedule 2; and (b) the water allocation security objective stated in section 12. s 15 10 s 17 Water Resource (Boyne River Basin) Plan 2000 15 Restriction on full supply level of Awoonga Dam Full supply level for Awoonga Dam must not be more than 45 m AHD. 16 Restriction on volume of water available from Awoonga Dam (1) The maximum volume of water available to the Gladstone Area Water Board from Awoonga Dam is as follows— (a) at full supply level 30 m AHD—63 000 megalitres a year; (b) at full supply level 45 m AHD—113 600 megalitres a year. (2) For a full supply level that is between the levels stated in subsection (1)(a) and (b), the maximum volume is calculated using the IQQM computer program. 17 Releases from Awoonga Dam for the environment (1) This section applies if the full supply level of Awoonga Dam is more than 30 m AHD. (2) Appropriate infrastructure must be incorporated into the dam to accommodate releases for the environment downstream of the dam. (3) Water released downstream from the dam must be from the upper oxygenated layers of water in the dam. (4) Subsections (5) to (7) apply if the dam’s actual water level is at least 30 m AHD. (5) For each day of a month stated in schedule 3, column 1, the following volume of water must be released from the dam for the benefit of the downstream environment— (a) the volume stated for the month in schedule 3, column 2; or (b) for any day on which the stream flow into the dam is less than the volume mentioned in paragraph (a)—the volume of the stream flow. (6) Subsection (7) applies whenever the stream flow into the dam is at least 3 210 megalitres a day for 4 or more consecutive days (the “consecutive inflow days”). (7) For the benefit of the environment downstream of the dam, an average of at least 3 210 megalitres of water a day must be released from the dam— s 18 11 s 20 Water Resource (Boyne River Basin) Plan 2000 (a) immediately after day 4 of the consecutive inflow days ends; and (b) for an equal number of consecutive days as the consecutive inflow days. 18 Releases from Awoonga Dam for downstream users (1) Appropriate infrastructure must be incorporated into Awoonga Dam to accommodate releases for licensees and permittees downstream of the dam. (2) Water released downstream from the dam must be from the upper oxygenated layers of water in the dam. (3) Sufficient water must be released for the licensees and permittees to be able to take the amount of water allowed to be taken under their licences or permits. 19 Restrictions on taking water from Boyne River downstream of Awoonga Dam The chief executive may grant a licence for taking water from the Boyne River downstream of Awoonga Dam (the “relevant area”) only if the volume of water allowed to be taken under the licence— (a) is not more than 40 megalitres a year; and (b) does not result in the total volume of water allowed to be taken from the relevant area under licences being more than— (i) if the dam’s full supply level is not more than 30 m AHD—400 megalitres a year; or (ii) if the full supply level is more than 30 m AHD—800 megalitres a year. 20 Restriction on taking water upstream of Awoonga Dam full supply level or from Awoonga Dam (1) The chief executive may grant a licence or permit for taking water upstream of Awoonga Dam full supply level or from Awoonga Dam (the “relevant area”) only if— (a) the volume of water allowed to be taken under the licence or permit is not more than— s 20 12 s 20 Water Resource (Boyne River Basin) Plan 2000 (i) for stock and domestic purposes—20 megalitres a year; or (ii) for town water supply—200 megalitres a year; or (iii) for other purposes—160 megalitres a year; and (b) the volume of water allowed to be taken under the licence or permit does not result in the total volume of water allowed to be taken from the relevant area under licences or permits being more than— (i) for town water supply—200 megalitres a year; or (ii) for purposes other than town water supply, stock, domestic or temporary purposes— (A) if the dam’s full supply level is not more than 30 m AHD—1 500 megalitres a year; and (B) if the dam’s full supply level is more than 30 m AHD—3 000 megalitres a year; and (c) the chief executive imposes on the licence or permit a condition that water may be taken from a watercourse, lake or spring in the relevant area only if— (i) the water in the watercourse, lake or spring is flowing; and (ii) taking the water does not stop the water in the watercourse, lake or spring flowing immediately downstream of the point where the water is taken. (2) Subsection (1)(c) does not apply to— (a) a permit for stock or domestic purposes or for town water supply; or (b) a licence to take from Awoonga Dam. (3) In subsection (1)(b)(ii)— “temporary purpose” means a purpose for which a permit may be granted under the Water Resources Act 1989, section 56(1)(b).2 2 Water Resources Act 1989, section 56 (Power to issue permit to government department, other person or body to take water) s 21 13 s 22 Water Resource (Boyne River Basin) Plan 2000 21 Entitlement expressed as an area (1) This section applies if a licence has an entitlement expressed as an area. (2) To calculate, for section 20(1)(b), the total volume of water assumed to be taken from the relevant area, the volume of water, in megalitres, assumed to be taken under the licence is calculated by multiplying the area in hectares by 4.4. (3) The chief executive must amend the licence to state the entitlement in megalitres. 22 Requirement to consider criteria (1) The chief executive must consider the following criteria in deciding an application for or about a licence or permit relating to the plan area or in imposing conditions on a licence or permit— (a) the purpose for which the water is intended to be taken; (b) the volume of water intended to be taken; (c) the availability of water for the intended purpose; (d) the potential impact of the proposed taking on— (i) the entitlements of all users of water in the plan area; and (ii) the ecological value and function of instream environments and related areas including, for example, riparian zones; (e) the efficiency and sustainability of the proposed taking; (f) the availability of an alternative water supply for the intended purpose including the more efficient use of water already available to the licensee or permittee; (g) whether the volume of water intended to be taken under the licence or permit should be restricted or a meter approved by the chief executive used to measure the volume of water taken; (h) whether the taking should be restricted during particular periods, including, for example, when— (i) there is no water flow in the watercourse; or (ii) the flow is insufficient for downstream water users or to sustain the health of ecosystems; or s 23 14 s 23 Water Resource (Boyne River Basin) Plan 2000 (iii) water is released for the benefit of the environment downstream of the dam; (i) whether the proposed taking may restrict the movement of fish or other aquatic species; (j) the extent to which rapid artificial variations in instream water levels may adversely affect the environment; (k) the impact of water infrastructure on water quality; (l) the impact on the natural variability and duration of seasonal streamflow patterns. (2) This section does not limit the matters the chief executive may consider in deciding an application or imposing conditions. (3) However, any other matters considered must be consistent with the outcomes under part 3.
