❓ A WA parliamentary question on notice addresses water monitoring practices in the Swan/Avon and Yilgarn drainage systems, raising concerns about reduced monitoring, volunteer reliance, data accessibility, and environmental protection. The Minister's response details station closures, monitoring parameters, data availability, and objectives.

QuestionView source ↗
I refer to the siting, maintenance and record keeping of the water monitoring stations for the Swan/Avon and the Yilgarn drainage systems, which were for many decades the responsibility of the Water Authority of WA and later the Waterways Commission -
(1) In recent years has the Water and Rivers Commission reduced the number of monitoring stations along the Avon River between Brookton and Toodyay?
(2) If so, for what reason?
(3) Can the Minister provide the names of those stations which have been discontinued altogether?
(4) Can the Minister provide the names of those stations which have been simplified to record only such basic information as pH, conductivity, nutrients, water volume and rate of flow?
(5) Given the serious environmental damage which could/does result from the increasing number of drains being constructed to carry off both surface water and ground water from farms in the Yilgarn drainage system into the adjoining Swan/Avon Drainage system, would the Minister affirm categorically that sufficient new water quality and water volume monitoring sites have been or are being established to capture vital ‘before’ and ‘after’ data?
(6) Is the Minister aware that currently, water monitoring in the Shires of Beverley and York depends on unpaid volunteers who collect and record data and make the data available to the Water and Rivers Commission?
(7) Given the high level of public interest in environmental issues, especially those to do with our river systems, will the Government ensure that newly gathered water monitoring data, including data collected by State Government agencies, the CSIRO and private consultants is electronically immediately available to the public and updated on a monthly basis?
(8) Can the Minister affirm that the objective for collecting water quality data has been extended to include the protection of aquatic biota and natural ecological systems, in addition to the provision of water which can safely be used for human consumption or for commercial purposes?

(1) Yes, two streamflow gauging stations have been closed since January 2000 along the Avon River. (2-3) The Broun's Farm streamflow gauging station (between York and Beverley) was closed as the newly installed and upgraded stations at York and Beverley rendered Broun’s Farm obsolete. It remained open for a number of years only to establish an accurate relationship with the newer flood warning stations in York and Beverley. Natural features made Broun’s Farm inferior in both quality and access to the newer stations. The Jelcobine streamflow gauging station (upstream of the Waterhatch station on the Dale River) was closed because it was more cost effective to gauge a greater proportion of the Dale River catchment at the Waterhatch station. (4) The parameters of insitu pH, conductivity, nutrients, and flow have been historically monitored and are the parameters that are currently being monitored at Avon streamflow gauging stations. Some stations on the Avon have now been upgraded to measure salinity at a very fine time interval of 30 minutes or less using a conductivity meter. Nutrient sampling on the Avon River system is now taken monthly when flowing at Northam Weir, Frenches Siding, Odriscoll’s Farm, Balladong Bridge at York, Beverley Bridge and Waterhatch Bridge. (5) The pre existing gauging station network provides some information on changes to catchment management. For the example given at Yenyening lakes, the gauging stations at Kwolyn Hill, Gairdner’s Crossing and Mooranoppin Rock provide data from the catchments feeding into the Yenyening Lake. The lake outflow is gauged at Yenyening Lakes station and the Avon River above the lake confluence is gauged by the Qualandary’s Crossing station. The Dale River is gauged at Waterhatch station approximately 5km upstream of the Dale/Avon confluence. Gauging station placement is governed by a number of natural features such as a good natural control, a contained floodplain and access considerations. (6) Water quality monitoring in the Shires of Beverley and York is carried out by regular in-situ analysis by Water and Rivers Commission staff at stream gauging stations at Beverley, Dale River/Avon River confluence and York townsite. This data is complemented by regular sampling and analysis by community volunteers working under the auspices of Beverley Friends of the River and York River Conservation Society who have been trained and resources provided by Commission staff under the Avon Community Water Quality Program. The data is collated and interpreted by Commission staff then shared with the communities of York and Beverley and the Ribbons of Blue Program. (7) All collected data on the Avon has and will continue to be freely available to the public upon request. Currently all continuous data collected at the Avon stations is available in a raw, unverified format via the Department of Environment’s web site. This data is updated daily during normal low flow periods and more regularly during high flow periods. Continuous data is downloaded, processed and verified every 6 months at which point the data is archived and exported to a central database and made available upon request via the data provision group. Water quality data is generally available from the DoE’s data provision group within 21 days initial sampling. (8) The streamflow and water quality gauging station network of the Commission provides the hydrologic information needed to aid in defining, using, and managing Western Australia's invaluable surface waters. The stream-gauging network provides a continuous source of well-archived, well-documented, and unbiased water data that are used in many ways by the community, government and industry. The water quality data are used to assist in the understanding and assessment of aquatic ecosystems along the Avon River.
