JUDGMENT
Water Management Act 2000 (NSW)
Crimes (Sentencing Procedure) Act 1999 (NSW)
Statement of agreed facts
12 Below is an aerial image of Dromore Station and surrounds depicting the location of the water supply works and their associated meters at Dromore Station as labelled by the NRAR. 13 The stretch of the upper Murrumbidgee River which adjoins Dromore Station is part of the "Murrumbidgee II Water Source", whose boundaries are identified in the map at [18] below. Under the Water Management Act 2000 (WM Act), the Murrumbidgee II Water Source is a water source to which Part 2 of the WM Act applies. 14 At all relevant times, Ken Kimber has been the holder of licences having effect under the WM Act which conditionally permitted, and permit, the taking of water from the Murrumbidgee River to be used for the purposes of irrigating crops on Dromore Station. Former Water Surface Licences 15 When Ken and Judith Kimber purchased Dromore Station in 2010 and in 2012, they also purchased the surface water licences previously held by the outgoing owner of the land. Specifically, when the Kimbers purchased Dromore Station, Ken Kimber became the holder of the following water surface licences: a. unregulated water surface licence No. 40SL042535 with an allocation for irrigation of 2,273 megalitres per water year a copy of which is at Tab A; and b. unregulated water surface licence No. 40SL042573 with an allocation for irrigation of 2,273 megalitres per water year a copy of which is at Tab B. 16 Each of those water surface licences held by Ken Kimber included a condition (Condition 7) in the following terms, being a condition of a type known as a "cease to pump" condition: The licensed work shall not be used for the purpose of irrigation unless the flow of the Murrumbidgee River at the Billilingra Gauge (upstream of Bredbo) exceeds 15 megalitres per day with such flow corresponding to a reading on the said gauge of 0.58 metres (or such other reading as may be determined from time to time). The coming into force of the 2012 Water Sharing Plan 17 From 4 October 2012, the Water Sharing Plan for the Murrumbidgee Unregulated and Alluvial Water Sources 2012 (2012 WSP) applied to the Murrumbidgee II Water Source. A copy of the 2012 WSP is at Tab C. 18 A map extracted from the 2012 WSP showing the Murrumbidgee II Water Source is below. Factors influencing water flow in the Murrumbidgee II Water Source 19 Water flow in the section of the upper Murrumbidgee River comprising the Murrumbidgee II Water Source, including the section of the river adjacent to Dromore Station is dependent on a combination of natural rainfall and run-off from tributaries and agreed releases of water from the Tantangara Dam, by the Snowy Hydro Limited, pursuant to its Corporate Licence under the Snowy Hydro Corporatisation Act 1997. 20 River discharge is managed at Tantangara Dam by Snowy Hydro Limited with a base flow target of 32 ML/Day as measured at Mittagang Crossing, Cooma (410033). 21 Snowy Hydro Limited's Corporate Licence provides for the release of an agreed annual volume of water from Tantangara Dam into the Murrumbidgee River. The volume of water available for irrigation in the Upper Murrumbidgee will depend on the volume of water being released from Tantangara Dam by Snowy Hydro Limited. The Conversion of the former surface water licences into combined approvals and water access licences under the WM Act 22 On and from 4 October 2012, upon commencement of the 2012 WSP, the entitlements held by Ken Kimber under Surface Water Licences Nos. 40SL042535 and 40SL042573, were converted into combined approvals and water access licences (WALs) under the WM Act. 23 In so far as those former entitlements conferred rights to the use of water supply works, (pumps etc) for specified purposes, the entitlements were converted by operation of the law, pursuant to transitional provisions of the WM Act, into combined water supply works and water use approvals under the WM Act. 24 A Combined Water Supply Works and Water Use Approval under the WM Act authorises the holder to construct and use a specified water supply work at a specified location, and to use water for a particular purpose at a particular location. A water supply work is the means by which water may be taken pursuant to a water access licence. 25 In so far as the former entitlements under the surface water licences permitted the extraction of water from the Murrumbidgee II water source, they were converted by operation of the law, pursuant to transitional provisions of the WM Act, into water access licences (WALs) under the WM Act. 26 Specifically following the commencement of the 2012 WSP on 4 October 2012, the entitlements under the two former Surface Water Licences Nos. 40SL042535 and 40SL042573 were converted to combined works approvals and water access licences under the WM Act as follows: a. Surface Water Licence No. 40SL042573 was converted to Combined Works Approval No. 40CA414168 and WALs Nos 33305 and 33285; and b. Surface Water Licence 40SL042535 was converted to Combined Works Approval 40CA414165 and WALs Nos. 33291 and 33297. 27 Each of the WALs conditionally permitted the extraction of water from the water supply work in use at a specified location as identified in the nominated works approval to which the WAL related. The nominated water supply works and WALs at Dromore Station were relevantly as follows: Work Description Applicable Approval and WAL Work 1 A pump on Lot 1 of DP 632939 which fed water to an irrigation pivot primarily located on Lot 15 of DP 750569. 40CA414168 (WAL 33305) Work 2 A pump on Lot 8 of DP 750569 which fed water to an irrigation pivot located on the same Lot and Lot 1 of DP 632939. 40CA414168 (WAL 33305) Work 5 Two conjoined pumps located on Lot 2 of DP 544984, which fed water primarily to an irrigation pivot located on the same lot 40CA414165 (WAL 33291)
The continued operation of Condition 7 from 4 October 2012 to 19 February 2018 28 Pursuant to the transitional provisions of the WM Act, the WALs which came into effect on the coming into force of the 2012 WSP remained subject to the conditions of the surface water licences which they replaced in so far as the conditions were applicable to the extraction of water. 29 In particular, on and from 4 October 2012, Condition 7 of the water surface licences (i.e., the cease to pump condition extracted at [16] above) continued to apply to the WALs under the WM Act that replaced the former water surface licences. 30 On around 25 March 2014, Ken and Judith Kimber received written notice from the NSW Department of Primary Industries (Office of Water) that "the conditions for the Water Sharing Plan for your area have not been developed as yet, in the interim you must abide by the conditions of your previous Water Act licence". A copy of this letter is at Tab D. This remained the position until 19 February 2018. That is, Condition 7 continued to apply to the taking of water under the WALs until 19 February 2018 when Ken Kimber received letters from the Department of Industry which are referred to below. The Flow Condition notified on 19 February 2018 31 On 17 February 2017, Ken Kimber received a letter from the Department of Primary Industries (Water) inviting submissions in response to a Status and Issues Paper that had been released for the Murrumbidgee surface water resource. A copy of this letter is at Tab E. The Status and Issues Paper to which the letter referred is at Tab F. 32 On 31 March 2017, Ken Kimber, on behalf of a group of irrigators in the Upper Murrumbidgee system, sent a submission to the Department of Primary Industries in response to the SW9 Status and Issues Paper. A copy of this submission is at Tab G. 33 On 19 May 2017, Ken Kimber received a telephone call and had a discussion with David Bishop (Water Planner at the NSW Department of Industry) who said that he was not aware of any proposal to change the cease to pump rules. 34 Ken Kimber did not receive any other communications from DPI Water in response to the submission made on 31 March 2017, nor any communications in relation to licensing until 19 February 2018. 35 Under cover of letters dated 19 February 2018, which letters Ken and Judith Kimber received by post, the Department of Industry sent Ken and Judith copies of amended versions of their water access licences under the WM Act. Unregulated River Licences a. WAL 33305 (40AL414167), being an "Unregulated River" category licence with a share component of 2,273 units (nominating Approval 40CA414168); b. WAL 33291 (40AL414164), being an "Unregulated River" category licence with a share component of 2,273 units (nominating Approval 40CA414165); Domestic and Stock Licences c. WAL 33285 (40AL414166), being a "Domestic and Stock" category licence" with a share component of 5.5 ML (nominating Approval 40CA414168); d. WAL 33297 (40AL414163), being a "Domestic and Stock" category licence with a share component of 5.5 ML (nominating Approval 40CA40414165). 36 The Department of Industry letters included the following notification: There are two types of conditions that apply to licences and approvals: a. Plan conditions that are required to be imposed by the Murrumbidgee Unregulated and Alluvial Water Sources. These apply immediately to your licence and/or approval and are identified with the letter 'M' b. Other conditions that are proposed to apply to your licence and/or approval which are identified with the letter 'D' or 'N'. Copies of your approvals/licences are attached. If you have concerns about the conditions marked 'D' or 'N' please contact WaterNSW to make a submission within 28 days from the date of this letter 37 WALs Nos. 33305 and 33291 attached to the Department of Industry letter of 19 February 2018 contained an amended form of cease to pump condition as compared with Condition 7 referred to and extracted at [16] above. The cease to pump condition contained in each of those WALs attached to the letter of 19 February 2018 was in the following amended terms (Flow Condition): "Water must not be taken from the Murrumbidgee II Water Source when flows are in the Very Low Flow Class, which means that the flow is 27ML/day or less at the Murrumbidgee River Billilingra gauge [No. 410050]. This restriction does not apply if water is to be taken from an off-river pool, an off-river dam pool, a runoff harvesting dam or an in-river dam pool". 38 The Flow Condition was identified with the letter "M" as a mandatory condition, and, as such, it fell outside the scope of the discretionary conditions as to which submissions had been invited by the Department of Industry in its letters. 39 The letters also enclosed copies of Approval 40CA414168 and Approval 40CA41465. 40 At all relevant times from on or about 19 February 2018, upon the notification provided by way of the Department of Industry letters of that date, WAL 33305 and WAL 33291, were subject to the Flow Condition in the form set out in paragraph 43 above. That is, Condition 7, which related to the height of the river corresponding to a reading on the Billilingra Gauge of 0.58 metres ceased to apply. The Flow Condition did not contain a reference to the height of the river. 41 Work 1 extracted water from an anabranch channel of the Murrumbidgee River (being a section of the river that diverts from the main channel and re-joins the main channel downstream). Works 2 and 5 extracted water from the main channel of the Murrumbidgee River. None of Works 1, 2 and 5 extracted water from an 'off-river pool', an 'off-river dam pool', a 'runoff harvesting dam' or an 'in-river dam pool'. 42 At the time Ken Kimber received the Department of Industry letters of 19 February 2018, he did not read them. He gave them to his administrative assistant for filing. He did not realise that the cease to pump condition on his water access licences had been changed. Ken Kimber did not make Luke Kimber aware of these letters and did not provide him with copies of them. 43 It was not until after 12 December 2019 when the NRAR officers attended Dromore Station (as referred to below), that Ken Kimber first read the letters dated 19 February 2018. 44 On 2 November 2018, Ivars Reinfelds, Senior Research Scientist in the Department of Primary Industries sent an email to lpkimber@bigpond.com titled "Murrumbidgee flows and rules", which referred to the Flow Condition of 27ML/D. A copy of this email is at Tab J. Metering data 45 At all relevant times, Works 1, 2 and 5 were metered with a State-owned electromagnetic water flow meter together with a data logger and data telemetry equipment. Each telemetered meter was installed in connection with a water outlet pipeline connected to the relevant water supply work. When water was pumped from the river, the flow meter collected flow information and stored it locally. The data was then sent every 15 minutes to a remote telemetry unit (RTU) located adjacent to the meter. From the RTU, the data was transmitted to WaterNSW's ClearSCADA system. 46 During the charge periods, the meters connected to Works 1, 2 and 5 did not log any events or alarms indicating that the normal function of the meter had been disturbed (for instance, because of a communication failure or a low battery), and no changes or amendments were made to the data. Flow rate data 47 At all relevant times, WaterNSW operated a water monitoring station at Billilingra Gauge (station number 410050) which was used to generate real-time flow rate data for the Murrumbidgee River at that location. 48 Billilingra Gauge is downstream of Dromore Station. 49 In general terms, the flow-rate data is processed as follows: a. a level sensor at the gauge records the height of the river at the gauge location ("river height data"); b. the river height data is transmitted at regular intervals to WaterNSW's electronic databases via telemetry; c. the river height data is used by WaterNSW's systems to generate "flow data", based on a Rating Table which plots the relationship between river height and river flow (discharge); and d. the flow data is automatically published on WaterNSW's real time data website and WaterLive app and updated approximately every hour ("provisional flow rate data"). 50 As part of WaterNSW's quality assurance procedures, water monitoring officers attend the Billilingra Gauge approximately every two months to perform routine maintenance tasks and to take certain steps to validate the previously recorded flow rate data (after which "quality assured data" is produced). 51 During these site visits, the water monitoring officers check that the level sensor is accurately recording the height of the river (allowing for a margin of error of +/- 10mm). Where required, the previously recorded river height data is adjusted to take account of any inaccuracies arising beyond the accepted margin of error. No such adjustment was required for the duration of the offence periods. 52 During these site visits, the water monitoring officers also perform "gaugings", which are manual point-in-time measurements of the flow rate of the river. Collecting gaugings over time enables WaterNSW to continue to validate and refine the Rating Table (by ensuring that gaugings are falling within plus or minus 10% of the flow rate predicted by the Rating Table). If an update to the Rating Table is made after a site visit, recent river flow rate data may be re-interpreted with the updated Rating Table to reflect the refined plot of the relationship between river height and river flow. This occurred for the flow rate data during the offence periods. The quality assured version of the flow rate data reflects an update to the Rating Table. 53 After these steps are completed, the provisional data (incorporating any adjustments) is archived by WaterNSW as "quality assured data". Quality assured data is available on WaterNSW's website (see [57] below). Data published online 54 At all relevant times, WaterNSW used provisional flow rate data to publish "live" water levels (river height) and flow rates for the Billilingra Gauge, at hourly intervals, via its real-time-data website and the WaterLive app. The "WaterLive" app is a publicly available application for Android and Apple IOS devices which provides access to WaterNSW's water monitoring data. 55 At all relevant times, the WaterLive app could be used to access the following information for the Billilingra Gauge: a. the water level (river height) at the gauge as at the most recently recorded hourly interval (including a time stamp of when this value had last been updated); b. the recorded flow rate at the gauge at the most recently recorded hourly interval (including a time stamp of when this value had last been updated). 56 The data published by WaterNSW on the real-time-data website also includes a Daily River Report for the Murrumbidgee River, which publishes the water level and flow rate at different gauges along the river (including the Billilingra Gauge) as at 6 am every day. The Daily River Reports for 19 November 2019 to 13 December 2019 are at Tab K. 57 Once quality assured data has been generated in accordance with the steps outlined at [50]-[52] above, it replaces the provisional data published on WaterNSW's website (which is referred to at [54] above). The Offending Conduct 58 In November 2019, Luke Kimber planted summer fodder crops at Dromore Station, including corn. He used water extracted from the adjacent Murrumbidgee River under Ken Kimber's WALs to irrigate those crops. 59 During certain periods between 20 November 2019 to 12 December 2019, Luke Kimber extracted a total volume of approximately 95.18 megalitres of water from the river for irrigation of the corn, lucerne and other crops on Dromore Station in circumstances when the taking of water was prohibited by the Flow Condition in WALs 33305 and 33291. 60 The extraction of this approximately 95.18 megalitres of water in contravention of the Flow Condition constitutes the offending conduct in these proceedings. In respect of the taking of that water, Ken Kimber is guilty of the offences charged against him under s 60B of the WM Act as the holder of the WALs and Luke Kimber is guilty of the offences charged against him as the person who took the water. 61 The circumstances of the offending conduct is further explained below. 62 Luke Kimber took water pursuant to WAL 33305 via Works 1 and 2, when the flow rate in the Murrumbidgee River was below 27ML/day at Billilingra Gauge, as specified in the Sequence 1 charge as follows: Seq Pumping period Flow in river at start and finish Flow in river at start and finish Height of river at start and finish Quantity of water taken (quality assured data) (live data) Work 1 1(a) 20/11/19 20:15 12.338 ML/day 11.826 ML/day 0.592 3.28 ML - - - - 21/11/19, 10:00 10.590 ML/day 10.325 ML/day 0.583 1(b) 23/11/19 17:00 6.187 ML/da 6.984 ML/day 0.556 3.75 ML - - - - 24/11/19 8:45 5.667 ML/day 6.554 ML/day 0.552 1(c) 24/11/19 13:30 4.927 ML/day 5.938 ML/day 0.546 5.32 ML - - - - 25/11/19 15:00 1.945 ML/day 3.227 ML/day 0.514 1(d) 2/12/19 8:15 1.589 ML/day 2.888 ML/day 0.509 9.23 ML - - - - 3/12/19 22:30 9.297 ML/day 9.384 ML/day 0.576 1(e) 11/12/19 18:45 13.390 ML/day 12.878 ML/day 0.597 11.12 ML - - - - 13/12/19 11:00 13.390 ML/day 12.878 ML/day 0.597 Work 2 1(f) 20/11/19 9:00 13.390 ML/day 12.878 ML/day 0.597 3.83 ML - - - - 21/11/19 00:15 12.338 ML/day 11.826 ML/day 0.592 1(g) 22/11/19 6:30 8.270 ML/day 8.620 ML/day 0.57 16.61 ML - - - - 25/11/19 12:00 2.076 ML/day 3.368 ML/day 0.516 1(h) 25/11/19 13:30 1.945 ML/day 3.227 ML/day 0.514 4.38 ML - - - - 26/11/19 8:15 0.595 ML/day 1.676 ML/day 0.488 1(i) 1/12/19 17:00 1.339 ML/day 2.634 ML/day 0.505 4.00 ML - - - - 2/12/19 9:30 1.589 ML/day 2.888 ML/day 0.509 1(k) 11/12/19 18:45 13.390 ML/day 12.878 ML/day 0.597 3.61 ML - - - - 12/12/19 12:30 12.338 ML/day 11.826 ML/day 0.592
63 Luke Kimber took water from the Murrumbidgee River pursuant to WAL 33291 via Work 5, when the flow rate was below 27ML/day at Billilingra Gauge, as specified in the Sequence 12 charge as follows: Seq Pumping period Flow in river at start and finish Flow in river at start and finish Height of river at start and finish Quantity of water taken (quality assured data) (live data) Work 1 12 20/11/19 13:30 12.338 ML/day 11.826 ML/day 0.592 22.41 ML (a) - - - - 25/11/19 07:30 3.094 ML/day 4.378 ML/day 0.529 12 1/12/19 20:00 1.460 ML/day 2.759 ML/day 0.507 2.59 ML (b) - - - - 2/12/19 9:00 1.460 ML/day 2.759 ML/day 0.507 11/12/19 17:15 13.390 ML/day 12.878 ML/day 0.597 12 (c) - - - - 1.68ML 12/12/19 13:00 12.544 ML/day 12.031 ML/day 0.593 12 12/12/19 17:15 12.962 ML/day 12.449 ML/day 0.595 3.37 ML (d) - - - - 13/12/19 11:00 13.390 ML/day 12.878 ML/day 0.597
Stop Work Order - 13 December 2019 64 On 12 December 2019, the Natural Resources Access Regulator (NRAR) was forwarded a complaint made to WaterNSW by an employee of the ACT Government in relation to irrigation activities at Dromore Station. 65 At approximately 3.15 pm on 12 December 2019, NRAR authorised officers Graeme White and Charlotte Whiteley attended Dromore Station. Upon arriving at the site, Mr White observed that certain pumps on the property were operating, which appeared to be in contravention of the Flow Condition having regard to the live flow rates published on WaterNSW's WaterLive application at the time. 66 On 13 December 2019, Mr White signed a Stop Work Order addressed to Luke Kimber under s. 327(2) of the WM Act (a copy of which is at Tab L). On the same date, NRAR authorised officers David Thomas and Charlotte Whiteley attended Dromore Station and served a copy of the Stop Work Order on Luke Kimber. 67 On being served with the Stop Work Order, Luke Kimber ceased irrigating forthwith. Cooperation with Authorities 68 On 4 March 2020, NRAR authorised officers David Thomas and Jennifer Davis attended Dromore Station and inspected the property. The officers took photographs of the pumps and other infrastructure located on the property. 69 On 22 April 2021, NRAR Senior Investigators Andrew Mannall and Jennifer Davis conducted a further inspection of Dromore Station. Mr Mannall and Ms Davis took photographs of the water supply works on the property and recorded relevant GPS coordinates. 70 Ken Kimber and Luke Kimber cooperated with the NRAR authorised officers for the purpose of and during these inspections and otherwise co-operated with the NRAR officers during the course of the NRAR investigation. They voluntarily participated in records of interviews on 4 March 2020 and 23 April 2021 in each case declining to exercise their right to have a legal representative or support person present during the interview. 71 During his voluntary interview on 23 April 2023, Luke Kimber said, among other things: a. His dad does the financial side of things. b. His dad has no involvement with the operation of the irrigation aspect of the farm. c. He was the only person who has operated the pumps during the offence period. d. His dad does not do any of the starting or the stopping of the pumping, or deciding what needs water. e. He was not given a copy of a letter with the change to the cease-to-pump condition. He was aware of the old surface licence condition specifying a gauge height of "0.58". He saw a copy of it or his dad told him about it. f. He never looked at the flow of the river. He only looked at the height. g. To check the height of the river at the Billilingra gauge, he looked at the WaterLive app. h. He definitely did not check the water level every time before starting pumping but he did look at the Water Live App regularly. 72 In response to the question: "What's your knowledge of the water access licences that are associated with them? Like conditions, how you take the water", Luke Kimber said, "Yep. Um, yeah, well we're aware of the, um, twenty seven megs that we always worked on fifteen". 73 In relation to the attendance by NRAR officers at Dromore Station in December 2019, he also said: (a) "they said it's now twenty-seven. So that was the first time we'd ever seen anyone or heard from anyone about the levels, um, and especially about the change, like, I hadn't had a copy of that." (b) "they came and told us, no, it's now twenty seven, it's nothing to do with the height, it's just twenty seven megs a day".
