STRATEGIC REVIEW OF THE SURFACE WATER MONITORING NETWORK REPORT INTRODUCTION

1 INTRODUCTION

1.1 BACKGROUND It has been formally acknowledged that “water is our most precious resource” and that a key responsibility for the Government of Western Australia is to “look after all our water needs”. Western Australia is vast, relatively dry, and exhibits great hydrologic variability. A key responsibility of the Department of Water is “to make sound decisions on scientific evidence and accurate information” and to “collect and analyse water resource information, issue licences, regulate water use, protect its quality and prepare policies and plans critical to the future development of Western Australia and its people”. The Department of Water was created by the Government of Western Australia in 2005 in recognition of the strategic importance of water and to ensure that the state’s water resources are planned and managed to meet community requirements now and into the future. Good planning, design and management are dependent on reliable, long-term data. Information should be collected to establish the sustainable yield of the resource, change in the resource yield from climate change, impact of resource use on water resources and impact of land development on the resource. This has been occurring to a varying extent across Western Australia since the early 20th century. Much has changed since the initial monitoring network was established. Stream flow measurement in Western Australia commenced in the early 1900’s, however, active measurement of our potential water resources didn’t begin in earnest until the early 1960’s. The purpose of the surface water network has broadened since its inception. However, the fundamental objective of surface water measurement remains the same, to collect reliable data on the surface water hydrology of Western Australia. In recent years, surface water monitoring stations have been established to collect data to measure ecologically sustainable flows and resource condition. Flood monitoring has expanded not only to support flood studies and floodplain mapping but the floodwarning system managed by the Bureau of Meteorology. Hydrographic skills and experience in the Department are important to maintain in order to measure the surface water resource, measure the use of the resource and manage the surface water monitoring network. This comprehensive review follows on from smaller assessments undertaken during the 1980’s and 1990’s. It identifies the State surface water monitoring network based on the information needs now and the near future. The strategic review outlines briefly each regions current water resource management and planning issues. A list of current and desired surface water monitoring stations has been defined for the important water resource management catchments. Overall, this report clarifies the direction for water resource monitoring in priority management areas where social, environmental and economic pressures are increasing.

1.2 STATE WATER STRATEGY As the driest inhabited continent on the planet, Australia is familiar with managing the use of water resources. The 2003 State Water Strategy for Western Australia outlines the measures required to ensure a sustainable water future for Western Australia. Objectives under which this is anticipated to be achieved are: ▼ Improving water use efficiency in all sectors; ▼ Achieving significant advances in water reuse; ▼ Fostering innovation and research; ▼ Planning and developing new sources of water in a timely manner; ▼ Protecting the value of our water resources.

Our Reference 1045/B1/005e Page 1

STRATEGIC REVIEW OF THE SURFACE WATER MONITORING NETWORK REPORT INTRODUCTION

The State Water Plan 2007 also provides a strategic framework to manage water resources in Western Australia. Under the Plan, a whole of water cycle approach is adopted to address both the demand and supply of water for the State and to improve water security into the future.

1.3 REASONS FOR REVIEW There are a number of reasons for the Surface Water Monitoring Network to be reviewed. Information about surface water in the State needs to be collected in important management and planning priority areas and the Surface Water Monitoring Network provides the data. Information on surface water is required to balance the environmental and economic needs for water. The surface water monitoring stations purpose and proposed monitoring sites have been identified. This means where and why stations exist and are proposed. To manage and provide for water use, manage the risk to social and ecological values dependent on the water resource, the measurement of surface water quantity and quality is fundamental to explain changes in the hydrological response in a catchment. Increased demand for water and complexity in managing water around the State has caused greater pressure to collect surface water data and invest more in surface water monitoring. As the State develops further, water use and the demand for water will increase. Although water use efficiency is a key objective of the State Water Plan 2007, water resource management and water allocation planning will continue to grow in importance. Water data is collected in many ways depending on use of the data. Each surface water monitoring station such as a gauging station needs to have a purpose to define the data collection requirements. Establishing and maintaining operating systems for a surface water monitoring network requires management. The support for this surface water monitoring network will be a challenge and innovative collection processes implemented. Generally, longer term monitoring is required to estimate river flow and yield. Collected quantity and quality water data with an unknown quality may result in misleading information.

1.4 THIS REVIEW In the first part of the Strategic Review, the catchment characteristics (catchment size, rainfall, topography, morphology, hydrogeology, vegetation and hydrology), level of water use, potential demand for water, current and future water resource management and planning issues were examined for each catchment in the drainage division basins. Knowledge of the changes in the water resource condition was also used to identify areas of monitoring importance. For example, changes in hydrological response from changes in resource use or catchment management. Information for the review was gathered extensively from water resource managers, scientific officers, regional hydrographers, and business and asset managers. The purpose of each surface water monitoring station was reviewed and use classified. In many situations a surface water monitoring station had many uses and its importance increased significantly with length and quality of data available. Not all surface water monitoring stations were included in the review. Stations used to collect data for short term, project based investigations may not have been included. However, some of these sites may become part of the surface water network for a number of reasons. Support for network expansion has become problematic when short term projects with external funds cease. Other data user networks may collect data important to the Department. Collection and use of this data from other user networks can be an issue. Other user networks external to the department include other government departments and landcare groups, mining companies and irrigation cooperatives. Rainfall collected by the Bureau of Meteorology is very important to water resource management and arrangements should be made to improve the effectiveness of collecting rainfall data across the State, especially in catchments gauged for stream flow. The review has not attempted to re-examine or improve the data reported on the river basins reported in the 1982 publication of Streamflow Records of Western Australia. It is a review building on available and responding to the current information needs for the priority management areas in the State.

STRATEGIC REVIEW OF THE SURFACE WATER MONITORING NETWORK REPORT INTRODUCTION

The Strategic Review is about bringing together surface water monitoring into a network to serve the business interests of the department. Surface water monitoring may also include collecting data for initial assessments to investigate the status of a resource or a water related management issue. Specific project sites used to appraise flows and water levels for ecologically sustainable flows, changes in flows due to climate change, initiate investigations associated with the measurement of yield, measurement of salt load and concentrations and measurement of forest water balance are examples that have been identified and included under the use classifications associated with surface water monitoring stations. The review’s intent is to produce tables and maps for each drainage region with current and desired surface water monitoring sites and reasons for monitoring. It is not intented to propose how surface water monitoring stations are to be operated. The purpose of a surface water monitoring station has guided the use classification and as a consequence guide the data requirements for a station.

STRATEGIC REVIEW OF THE SURFACE WATER MONITORING NETWORK REPORT HYDROLOGY IN WESTERN AUSTRALIA

2 HYDROLOGY IN WESTERN AUSTRALIA

2.1 DRAINAGE DIVISIONS Western Australia is a very large state spanning some 2.53 million square kilometres in area. Landforms shape the topography and define the drainage divisions in the State. The four major drainage divisions have been classified, as follows: ▼ South West Drainage Division 314 500 km2 ▼ Indian Ocean Drainage Division 518 600 km2 ▼ Timor Sea Drainage Division 282 110 km2 ▼ Western Plateau Drainage Division 1 415 700 km2

These major drainage divisions are shown in Figure 2.1 and within each drainage division lie the State’s river basins. These river basins are outlined in Appendix A.

2.2 CLIMATE WITHIN DRAINAGE DIVISIONS Western Australia has a diverse climate, ranging from dry tropical in the northern Kimberley region to temperate in the south. Similarly the main rainfall months also vary from north to south. In the south the month with the greatest rainfall is typically July while in the north it is typically January. For simplicity, Western Australia can be divided into three hydrologic regions. These regions correspond to the dominate rainfall pattern. The region from Esperance to Geraldton experiences winter cold fronts as the primary source of moisture. Carnarvon to Kununurra is dominated by monsoonal rain and tropical cyclones during the summer months with the interior areas experiencing only small annual rainfall totals. The area from Geraldton to Carnarvon is a combination of the summer rain and winter rain regions. These are discussed in detail below.

2.2.1 SOUTH WEST DRAINAGE DIVISION The climate of the South West division is Mediterranean in character with warm dry summers and cool wet winters, but conditions become progressively more arid inland from the coast. The rainfall is typically frontal in nature and has a markedly seasonal distribution. The annual occurrence of rainfall is regular but annual amounts can vary considerably. The highest rainfall, 1200mm to 1400mm occurs in ranges adjacent to the coast but decreases markedly in quantity and reliability to about 250mm at the inland divide.

2.2.2 INDIAN OCEAN DRAINAGE DIVISION Most of the Indian Ocean Division experiences an arid subtropical climate, with some temperate conditions in the south. As it straddles the Tropic of Capricorn, the Division lies between the zones of regular winter or regular summer rainfall. The medium annual rainfall exceeds 300mm in the north and the south, but is less than 200mm in the central portion. The rainfall is variable in occurrence and quantity as it can originate from either the south westerly frontal systems or cyclonic rain and sometimes an interaction of both. Long periods of drought are characteristic of the Division, but severe flooding can and does occur.

2.2.3 TIMOR SEA DRAINAGE DIVISION The Timor Sea Division experiences a tropical climate with a distinct winter dry season which according to the Koppen classifications is described as a semi arid monsoonal climate. Most of the rain falls between November to April and is fairly regular in occurrence but variable in amount. The average annual rainfall ranges from 1400mm along the north-west coast to less than 400mm in the transition zone along the desert margin in the south. Most of the rain results from thunder storms producing heavy, localised falls, but the occasional cyclone can generate widespread, intense falls to produce general flooding.

STRATEGIC REVIEW OF THE SURFACE WATER MONITORING NETWORK REPORT HYDROLOGY IN WESTERN AUSTRALIA

2.2.4 WESTERN PLATEAU DRAINAGE DIVISION Most of the region lies in the arid zone, but the northern and southern extremities extend into the transition zone between the arid hinterland and the tropical or Mediterranean zones respectively. The region experiences extreme ranges in temperature variation, both diurnally and seasonally. The rainfall is generally less than 200mm per annum on average and is very variable and unreliable. The northern half of the region receives mainly summer rains, while the south receives either summer or winter rain, but the heaviest falls generally result from the inland penetration of cyclonic depressions during summer.

2.3 CLIMATE VARIABILITY AND CLIMATE CHANGE The modern world has begun to realise the phenomenon known as ‘climate change’. It is defined as ‘change in global weather patterns’ and described by ‘the long term alteration in global weather patterns, especially increases in temperature and storm activity, regarded as a potential consequence of the greenhouse effect’. Historically climate has for convenience been assumed to be stationary and that over time there has been no trends. However this assumption has now been shown to be otherwise. Climate change has contributed to reduced rainfall in the south west and possibly an increase in rainfall in the north of the State. Recent research indicates that by 2030 the reduction of rainfall in the south west may decline by as much as 20 per cent relative to 1960-1990 levels. Since 1950, records have shown Australian average temperatures have increased 0.90 C, and the frequency of hot days and nights has increased. Climate projections indicate that annual temperatures are likely to continue to rise in Western Australia. The most recent climate change predictions indicate the current dry conditions, which extend to many other parts of Australia in addition to WA, are likely to continue. Decreased rainfall coupled with increased temperatures will result in reduced run-off from water catchments, and it will lead to increased demand for water by the population, flora and fauna alike.

STRATEGIC REVIEW OF THE SURFACE WATER MONITORING NETWORK REPORT MEASUREMENT HISTORY IN WESTERN AUSTRALIA

3 MEASUREMENT HISTORY IN WESTERN AUSTRALIA

3.1 COMMENCEMENT OF SURFACE WATER ASSESSMENT Surface water monitoring in Western Australia commenced in 1897. Temporary river gauging stations were established on the Helena and Canning Rivers to assist planning of the Goldfields Water Supply Scheme. Between 1908 and 1911 a further nine river gauging stations were commissioned on hills streams near Perth to assess potential water supplies for the city. No further network expansion took place until 1939-40 when nineteen stations were established on some of the principal rivers in the south west of the state. It was not until the 1950’s and 1960’s that water resource monitoring began in the Indian Ocean Division and Timor Sea Divisions respectively. This was in response to a number of planned water supply projects. While the quality of these early records was sometimes poor and infrequent, they provide a starting point for measurement records. These early monitoring stations provide an example of the importance of collecting rainfall and stream flow data.

3.2 ESTABLISHMENT OF REPRESENTATIVE NETWORK The measurement of stream flow begun in the early 1900’s. However, it was not until the early 1960’s when the Public Works Department of Western Australia began to measure water resources in earnest with Federal Government support. The statewide approach was part of a national initiative to establish a stream flow network to define the hydrological characteristics of landforms represented in Australia. Support for the State’s surface water monitoring ceased in 1986.

4.1 NEED FOR HYDROLOGICAL DATA A sound understanding of quantity, quality and variability of Western Australia’s water resources is essential to fulfil the State’s objectives of efficiently conserving, managing and utilising the water resources. The State’s Surface Water Monitoring Network provides stream flow and rainfall data for water resource assessment. Currently, this surface water monitoring work is carried out in regional offices under the direction of Regional Managers. Additional support is provided from sections in Perth. Much work has been done in Western Australia to collect surface water information. This information is essential for the Department’s water resource management and planning functions. As the demand on water resources increases, development of water sources and supplies also increases. Information on the regions water resources is collected for many purposes. Some more common purposes include: ▼ Water Resource Assessment; ▼ Flood Studies; ▼ Waterways and Drainage Management; ▼ Salinity Management; ▼ Water Source Protection; ▼ Infrastructure Planning and Urban Water Management.

Studies to understand and predict stream flows, water quality, floods and sustainable yields are carried out by hydrologists. These studies depend on reliable hydrological data collected over time and spatially representing water resource and catchment conditions within each drainage division. Sites collecting quantity and quality data in the catchments are managed under the Surface Water Monitoring Network. The current and desired surface water monitoring stations are presented in subsequent sections of this report for each of Western Australia’s drainage regions.

4.2 SURFACE WATER MONITORING INDICIES Associated with the purpose for each station in the surface water monitoring network, a number of basic surface water monitoring indicies were evaluated to compare the quality of the record available. Each station’s purpose, the ‘what’ and the ‘where’, was examined with the indicies to understand its value to the surface water monitoring network. The surface water monitoring indicies included in the report are: ▼ Use classification; ▼ Period of record (open date of gauging station); ▼ Available data (% stage data, % flow data, % rainfall data, % salinity data); ▼ Discharge rating ratio (% max gauged flow/ peak recorded flow); ▼ Attached rainfall stations.

4.3 CURRENT REGIONAL MONITORING STATIONS In each region there are a number of river basins monitored for stream flow and rainfall. A list of stream monitoring stations for each river basin is given in Appendix B, with periods of record for each station. A short description of the water resource management and planning activities are also included for each river basin or catchment. These lists make up the current surface water monitoring network. Appendix D, lists the current rainfall monitoring stations for each river basin with periods of record, % rainfall data available and whether it is attached to a stream monitoring station.

STRATEGIC REVIEW OF THE SURFACE WATER MONITORING NETWORK REPORT STRATEGIC REVIEW METHODOLOGY

5 STRATEGIC REVIEW METHODOLOGY

5.1 HOW THIS STRATEGIC REVIEW HAS BEEN CARRIED OUT This review is intended to provide details about the monitoring purpose and location to the measurement business. The process conducted was to review the previous surface water monitoring network reports, identify changes in environmental and economic issues in priority management areas and clarify changes to the surface water monitoring network. Each surface water monitoring station was identified with a purpose and classified according to a new classification of use. Rainfall and stream flow stations were mapped to the Surface Water Management Areas and Regions, then tabulated basin by basin. Information about the site was recorded including purpose, operating status, period of record and data availability. The current rainfall and stream flow stations were compared to the designed stream flow monitoring network to characterise representative catchment hydrology in basins defined by PDK (Bill) Collins in “The Hydrologic Network for Western Australia (1982)” and the “Background Report on Surface Water Resources Assessment in Western Australia (1986)” compiled by the Western Australian Water Resources Council. Stations monitored for salinity were also reviewed. Overall there is a list of the current and desired stream flow and rainfall monitoring stations in each river basin. It recommends changes to the current hydrologic monitoring network based on priority and region. Surface water monitoring stations only provides in part the data for information about the hydrology of a catchment. This review has considered the stations use in a broader context. Information about the hydrology of a catchment also depends on data collected from water users such as mining companies.

5.2 SURFACE WATER MONITORING USE CLASSIFICATIONS The use of surface water monitoring stations has changed from measuring the rainfall and stream flow from representative catchments found in the landscape to a network to meet the information needs of the State’s water resource management and planning as broadly identified in the State Water Plan 2007. The new classifications for use of stream monitoring stations are listed and explained in Table 5.1.

Table 5.1: Description of Use Classifications for stream flow monitoring stations

Use Classification Explanation

STRATEGIC REVIEW OF THE SURFACE WATER MONITORING NETWORK REPORT STRATEGIC REVIEW METHODOLOGY

5.3 USE CLASSIFICATIONS Each stream monitoring station in the network may have a number of purposes. The primary purpose was identified and station classified according to its use in water resource management. Each use classification was defined and reasons for monitoring briefly explained.

5.3.1 URBAN WATER Measurement of drainage flow and water quality in catchments associated with urban development. Drainage water from developed areas flowing to downstream rivers and floodplains need to be measured to assess changes and provide information for management and plans.

5.3.2 SALINITY Water monitoring in catchments associated with salinity management. Stream flow and water quality is assessed to understand trends and changes in surface water and hydrological processes in catchments.

5.3.3 WATERWAYS Measurement of water quantity and quality to assess catchment and waterway health. Water measurement provides data to assess the health of a waterway like the measurement of nutrients contributing to changes in ecology. This information can be a basis for waterway management initiatives and for State and Local plans.

5.3.4 FLOOD Flood monitoring in catchments provides data for flood hydrology and hydraulic information required to assess recurrence of flood flows and flood mapping. Flood studies depend on river and floodplain water levels and measured flood flows. Flood assessments are required for statutory land planning processes.

5.3.5 WATER ASSESSMENT Information for water resource assessment and management such as sustainable yields, ecologically sustainable flows and water resource condition (depletion) depends on measurement of surface water flow. The assessment of spatial and temporal changes in catchment runoff and water quality depends on a well managed surface water monitoring network. Methods in assessing a water resource and its sustainable limit, depend on the measurement of water. Stream flow monitoring in catchments with a higher level of water resource management should be used as indicators for water allocation and resource management. Changes in catchment hydrology responding to climate change, demands on water resources and knowledge about water for the environment and interaction between groundwater and surface water are important for the development and revision of water plans. Data and information on these changes depend on a well managed surface water monitoring network. Some surface water monitoring stations used for water utility purposes will be important for water assessment. These stations may not be explicitly classified for water supply and may operate to collect flow data under compliance and water allocation management arrangements required for Statutory water resource management and planning.

5.3.6 CLIMATE CHANGE Surface water monitoring in catchments with stable land use or management are important in providing information on hydrological trends related to climate change. Good stream monitoring stations in catchments with little or no anthropological impact are extremely valuable to understand climate change.

6.1 MANAGEMENT AREA PRIORITISATION Water management and planning initiatives in the next five years recognise the need for data to produce information for regional water plans, water management plans, drainage (arterial) plans, and local natural resource management plans. The State’s water resource management has been divided into Surface Water Management Sub Areas which are based on the surface water catchments. These are identified in the Management Area Prioritisation (MAP) – Surface Water Statewide Priority Areas Water Resource Assessment table. The groundwater statewide priority areas were also included in MAP. A number of water allocation plans are under development and depend on past, current and future resource assessments of surface and groundwater resources. Surface water assessment for these sub areas will require data from the Surface Water Monitoring Network. A summary of the Management Area Prioritisation (MAP) for surface water is included below. The highest surface water priority areas have been identified for each region and Surface Water Management Area. These are shown in Table 6.1.

6.2 IMPORTANCE OF SURFACE WATER MONITORING Surface water monitoring data is fundamental to develop understandings about catchment hydrology, eco-hydrology and flow hydraulics and produce information for regional water plans, water resource management plans, drainage (arterial) plans, drainage and waterways management plans, floodplain management plans and local natural resource management plans. These plans are important to inform planning for development, resource use; protect environmental value and infrastructure. Data collected to provide information will be evaluated and analysed for trends and used to develop assessment tools such as models. Collected data may also be used by private consultants for other reasons in developing the State and protecting environmental assets. Real time data collected by the department is used by the Bureau of Meteorology for flood forecasting. State and Local Governments have roles and responsibilities in providing support for the flood forecasting service managed by the BoM. There are eleven river basins monitored for stream flow and level for floodplain management and are used in the flood forecasting. These river basins include the Fitzroy, DeGrey, Gascoyne, Greenough, Irwin, Moore, Swan/Avon, Murray, Collie, Preston, Vasse and Blackwood.

6.3 RAINFALL MONITORING Although this review focuses on why and where stream monitoring stations are located, rainfall monitoring stations are also essential. However, there are other rainfall data collectors, mainly BoM, that may be important to produce water resource information. Clearly, there are opportunities to improve and expand the rainfall monitoring network. This should be made a priority between data collectors. In the interim, it is expected a catchment if measured for stream flow to have at least one rainfall station. Ideally, rainfall should be measured for large catchments (>1000km2) in at least three parts of the catchment, lower, middle and upper. Rainfall monitoring stations are identified and included in the surface water monitoring network. However, it is not a dense network and many catchments may lack rainfall measurement.

6.4 REGIONAL REVIEWS OF SURFACE WATER MONITORING The sections that follow contain details about the surface water focus catchments; existing surface water monitoring in river catchments and basins; and proposed reopening of stream monitoring stations for each Region including: ▼ South Coast; ▼ South West; ▼ Kwinana Peel; ▼ Swan Avon (Goldfields); ▼ Mid West Gascoyne; ▼ Pilbara and; ▼ Kimberley.

STRATEGIC REVIEW OF THE SURFACE WATER MONITORING NETWORK REPORT SOUTH COAST REGION REVIEW

7 SOUTH COAST REGION REVIEW

The South Coast Region covers an area of 87 358 km2, bounded by Northcliffe to the west, Lake Dundas to the north and the Nullabor Plain to the east. The drainage catchments and rivers in the South Coast Region are as shown in Figure 7.1. Figure 7.2 shows a typical stream monitoring station in the South Coast Region. The South Coast Region lies within the South West Drainage Division and extends from the Meerup River catchment in the west to the extreme southern portion of the Salt Lake basin in the east. Most rivers flow to coastal inlets bounded by the Southern Ocean. The landform features are very diverse and the southward flowing rivers are characteristic of the region. In the east there are relatively flat areas of inland drainage and form highly valued wetland systems (Lake Warden wetland complex). Many of the rivers and coastal creeks drain to shallow coastal inlets. Granites and gneisses are exposed along the coast and inland form prominent features like the Porongurup Ranges. Exposed metamorphic forms can be seen in the Stirling Ranges and at Mt Barren. Generally, the south coast varies from forested incised river valleys in the west through scrub and heathland to dry salt lakes in the east. Many catchments have undulating plains and cleared for agriculture, viticulture, horiticulture and timber plantations. Other areas have been protected for floral diversity including the Fitzgerald River National Park recognised as an international biosphere reserve. Near coastal areas remain relatively uncleared and are mostly protected in national parks and other reserves. Rainfall tends to be less reliable from west to east with annual rainfall averages above 1000 mm in the west to below 550 mm in the east. Inland the annual rainfall drops to less than 450 mm. Coastal areas have mild to warm dry summers. Winters are cool and moist. Inland the climate is warm and dry in summers with occasional summer rain and cold dry winters. Rainfalls are influenced frequently by cold fronts and moist air from the north west producing thunderstorms. Data collected for surface water information is driven by development issues and the high value the region places on its environmental values of the area. There is a high interest in understanding the level of impact catchment activities have on coastal estuaries and inlets. Managing and protecting the relatively uncleared coastal fringe of the south coast is important for conservation, lifestyle and tourism. Water resource development and water source protection are emerging issues for south coast communities. Changes in water quantity and quality from land clearing are likely to have impacted streams and wetlands found in the eastern portion of the region. Mining activity, like the rest of the State, has increased in the region. Increase use of water and demand for water has increased the pressure on water resources in some catchments. Forest plantations have also increased and interest in how this affects streams flow to the coast. Forested catchments and potential irrigated horticultural areas are of particular interest in the south-western portion of the region The Shannon River catchment has had little development and remains in a natural state without anthropological influence. Surface water monitoring in this catchment is extremely valuable to understand the region’s climate change. Rivers and their catchments identified as pristine or near pristine are unique not only for conservation value but for understanding the affect climate change has on water resources. The current number of hydrological monitoring stations in the South Coast Region is summarised in Table 7.1. Details on these stations can be found in Appendices C1, D1 and E1, and locations are given in Figure 7.1.

Changes to surface water monitoring overtime will be influenced by local pressures and depend on priorities. A balanced and appropriate approach in collecting data needs to be aligned with the information needs of water resource management and planning in the region.

STRATEGIC REVIEW OF THE SURFACE WATER MONITORING NETWORK REPORT SOUTH WEST REGION REVIEW

8 SOUTH WEST REGION REVIEW

The South West Region covers an area of 37 680 km2. Major river systems are shown in Figure 8.1. The region stretches in the north to Yarloop, Meerup River to the south and the townships of Kukerin and Nyabing to the east. Figure 8.2 shows a typical stream monitoring station in the South West Region. The South West Region lies within the South West Drainage Division from Myalup in the north- west to the Warren River in the south-west; and inland to the upper catchment of the Blackwood River including Lake Toolibin, Broomehill, Manjimup and Pemberton. The broad landform zones represented in the region includes the Western Coastal Plain, Darling Range, Darling Plateau and the Southern Coastal Lowlands. The coastal margin is part of the Western Coastal Plain and is up to 40 kilometres wide. Sand dunes and plains built by wind blown sediment and inland towards the Darling Range alluvial sediment was built by river flood flow. The highest relief is found in the north where the deeply dissected south western edge of the Darling Plateau (Yalgarn block) presents as the Darling Range. Generally, the range has few individual peaks and is hilly or undulating. Deep valleys through this upland area of granite rock and lateritic soils drain river flow. Much of the Darling Range is forested and catchments provide water sources for the south west. Further inland the flat poorly drained upper Blackwood River catchment accumulates surface water flows from heavy rain in low lying areas to form shallow silt and salt basins. Along the south coast swift flowing rivers up-slope drain to the heath covered coastal lowlands that stretch from Cape Leewin to Esperance. Coastal sands from Yallingup to Augusta perculate rainwater causing large areas to cemented to form limestone. Caves are typical feature of the coastal fringe. The climate can be simply described as hot, dry summers and cool, wet winters. Rainfall is high (1100mm) along the west and southern coastal catchments and reduces inland to lower amounts of 350 mm. Streams draining to the west coast are generally shorter than those draining to the south coast. Larger river basins of the Harvey, Collie, Preston, Capel, Margaret, Blackwood, Donnelly and Warren drain forested upland country and flow to a variety of estuary and coastal wetland complexes. Grasses, shrubs and bushes including heath and acacia generally grow in the coastal areas. Trees in the wet sclerophyllous forest, such as Karri, Mari, Blackbutt, Bullich to name a few are found in the higher rainfall areas on upland slopes. Wandoo and Salmon Gum trees and acacias, grevilleas and other native shrubs in the eucalypt woodlands grow in the drier agricultural areas. Mallee grows in the eastern margins of the south west. Public drinking water supply catchments are another water resource management driver in the South West. Salinity in rivers is monitored in agricultural areas to understand the long term trends in cleared and rehabilitated catchments. Episodes of algal blooms and fish deaths have been symptomatic of catchment health and investigations are carried out to understand the cause. Surface water is also monitored to understand the impact and responses to catchment management. Challenges to the protection of public drinking water catchments has been an issue for water resource management. Urban development; viticulture; dairy farming; cereal crop production; horticulture; sand, bauxite and gold mining and tourism have significantly increased in the last decade compounding the demand for water. Interest in high environmental values and lifestyle has increased the importance in managing the environmental assets dependent on water. Drainage and flood management has increased with urban development. The Shannon River catchment has had little or no development and remains in a natural state without anthropological influence. Such wild river catchments have important conservation and biodiversity value and provide a unique opportunity to understand the affect of climate change on surface water.

Thirty two surface water monitoring stations currently operate for the purpose of drainage and waterway management, twenty six for flood information and twenty two for water assessment related to sustainable yield, ecologically sustainable flows and water resource condition. There is increased interest in understanding the sustainable yield and ecologically sustainable flows in different parts of the Blackwood River catchment and the smaller south west coastal streams. Improved water use and water resource management in the Collie River catchment has progressed. Changes in water quality and quantity from land clearing have impacted on streams and wetlands and increased river condition monitoring. The upper Harvey River catchment in southern jarrah forest of the Darling Range remains uncleared and important to monitor climate change. Stream flow and rainfall measurement is important in understanding water quantity changes from climate. Important focus catchments for surface water management and planning are listed below in Table 8.2.

STRATEGIC REVIEW OF THE SURFACE WATER MONITORING NETWORK REPORT KWINANA PEEL REGION REVIEW

9 KWINANA PEEL REGION REVIEW

The Kwinana Peel Region covers an area of 10 922 km2. Major river systems including the Murray, South Dandalup and Serpentine, drain westwards into the Peel Harvey Inlet. Figure 9.1 shows the Kwinana Peel drainage catchments and major rivers. Figure 9.2 shows a typical stream monitoring station in the Kwinana Peel Region. The Kwinana Peel Region lies within the South West Drainage Division from south of Fremantle to Preston Beach on the coast to the upper catchment of the Murray River including Wandering, Cuballing and Williams. The main landform features in the region include the coastal plain, Darling Range, Peel and Harvey estuaries and the upland areas of the Darling Plateau. Alluvial sediments east of the coastal fringe were built by the flood flows from the rivers draining the Serpentine, Murray and Harvey River catchments. The Darling Scarp runs parallel with the west coast and the highest relief is found near Dwellingup and Boddington including peaks of Mt Wells and Mt Saddleback. Many river catchments within the high rainfall zone draining from the upland area of the scarp provide surface water for the metropolitan area. The largest river, the Murray River, drains its upper catchment from the hills and flatter plains on the Darling Plateau. The climate is typically described as hot, dry summers and cool, wet winters. Rainfalls increase from the coast to about 1100 mm in the upland areas of the Darling Scarp and decrease to about 400 mm in the headwaters of the Murray River catchment. The large river basins of the Serpentine and Murray drain forested upland country to an estuary complex surrounded by wetlands and grassy floodplains used for agriculture and horticulture. Grasses, shrubs and bushes including heath and acacia generally grow in the coastal areas. Trees such as Jarrah and Marri are found on the higher rainfall upland slopes of the Darling Scarp. East of the dry sclerophyllous forest eucalypt woodlands extend to the drier agricultural areas. Other than mining, manufacturing, building and construction, retail and tourism, irrigated agriculture make a significant contribution to the region’s economy. The Peel region had a gross regional product of $5.5 billion in 2006-07 an increase of 21.5% over the previous financial year. Growth in population was unprecedented in the region because of the strong attraction to the recreational lifestyle offered by the Peel-Harvey coastal areas. A number of small surface water catchments lie in the Kwinana Peel Region. One of these catchments, the Serpentine River catchment area has a fully allocated surface water resource. The water resource has a high political value in this catchment and provides the only water supply for many users. Population and urban development is increasing significantly placing increased pressure on local water resources. Overall, water resource, urban drainage, waterway management is important to quality of urban living and high values in wetlands and estuaries in the area. Drainage management for urban developments, flooding in the lower Murray and Serpentine, water source catchments used for bauxite mining in the Darling Scarp all require some level of surface water monitoring data. Conjunctive use of water resources will require appropriate surface water monitoring. The current hydrological monitoring stations for the Kwinana Peel Region are summarised in Table 9.1. Details on these stations can be found in Appendices C3, D3, and E3, and locations are given in Figure 9.1.

In addition, important data collected for urban drainage by the Water Corporation will compliment the data collected from the department. The stream monitoring stations operated by the Water Corporation are registered as South Dandalup – West (614022) and North Dandalup – Lanstal Park (614070). The desired stream monitoring stations for the Kwinana Peel Region is given in Figure 9.3. Appendix F3 outlines details for these stations. There are fifteen rainfall monitoring stations currently operating in the region. Thirteen are attached to stream monitoring stations and two are located elsewhere in the catchment.

STRATEGIC REVIEW OF THE SURFACE WATER MONITORING NETWORK REPORT SWAN AVON (GOLDFIELDS) REGION REVIEW

10 SWAN AVON (GOLDFIELDS) REGION REVIEW

The Swan Avon Goldfields Region covers an area of 1,052,897 km2. Major river systems drain to the west from the Swan-Avon basin as shown in Figure 10.1. Figure 10.2 shows a typical stream monitoring station in the Swan Avon Region. The Swan Avon (Goldfields) Region lies within the South West Drainage Division from Yanchep to Fremantle on the coast to the upper catchments of the Avon River tributaries. The key landform feature on the coast is the Swan River estuary and its floodplain. The floodplain receives alluvial sediments from eroding areas from the Darling Scarp and upland areas east of the scarp. Further east of the Darling Range is the low sloping gradients of the highland. Shallow depressions and basins fill with silt and salts from heavy rains and a network of salt lakes are joined by waterways that drain slowly into the larger river catchments. The tributaries of the Avon River, the Salt, Camm and Pingrup drain significant areas where the rainfall is less than 350 mm. Flows from these tributaries only contribute to the Avon River when rainfall events are significant. The climate is typically described as hot, dry summers and cool wet winters. Rainfalls increase from the coast to about 1100 mm in the upland areas of the Darling Scarp and decrease to well below 350 mm in the headwaters of the Avon River catchment (Yilgarn). The large river basin of the Avon drains dry sclerophyllous forest and eucalypt woodlands to drier agricultural and mallee lands further to the east. In the northern and southern jarrah forest areas of the Darling Scarp, catchments provide surface runoff and groundwater recharge on which Perth’s integrated water supply system depends. Streams rarely flow in the Goldfields and flooding occurs from extreme rainfall events. Surface water information about drainage management for urban developments, flooding in the Avon and lower Swan River, water source catchments used for bauxite mining in the Darling Scarp will require ongoing surface water monitoring data. A flood study has been recently completed for the Avon between Toodyay to Beverley and includes the towns of Northam and York. The stream monitoring stations located on the Avon and the station at Wyalunga are important for flood monitoring. The real time data collected is used by the Bureau of Meteorology to provide flood forecasts. There are plans to upgrade these stations with support from the BoM and Fire and Emergency Service Authority for Perth’s Swan Avon Flood Warning System. Agriculture, irrigated horticulture, mining, cities and rural towns are well established. Rivers in the wheatbelt are significantly impacted by land salinisation. Rural drainage water quality, waterways, wetlands and estuary health; forest, conservation and water supply management in the Darling Range water source catchments depend on data collected by surface water monitoring stations. Gingin Brook and the groundwater aquifers associated with northern coastal plain including the Gnangara Mound provide a water resource for many conjunctive uses including irrigated horticulture. Surface water flows are dependent on the interaction between surface water and groundwater storages. Quality and quantity of urban and rural drainage is valued information for catchment drainage studies. Water quality knowledge and information on the Swan and Canning River estuary continues to depend on urban drainage and stream catchment monitoring stations. The current hydrological monitoring stations for the Swan Avon Region are summarised in Table 10.1. Details on these stations can be found in Appendix C4, D4, and E4, and locations are shown in Figure 10.1.

11 MID-WEST GASCOYNE REGION REVIEW

The Mid-West Gascoyne Region covers an area of 410 763 km2. Major river systems include the Moore, Murchison and Gascoyne Rivers as depicted in Figure 11.1. Figure 11.2 shows images of typical stream gauging stations in the Mid West Gascoyne Region. The Mid West Region lies within the Indian Ocean Drainage Division and extends along the west coast from Cape Range in the north to Moore River in the south and includes the upper catchments of the Murchison and Gascoyne Rivers. In the south the river valleys are formed by the Greenough, Chapman and Irwin Rivers. Spectacular sedimentary gorges have been created by the Murchison River and are prominent landform features. In the region, landform features are diverse and includes small ranges Moresby and Robinson and dissected Northampton block and breakaway country to the east. The Region tends to be relatively flat and in the eastern parts internal drainage forms numerous salt lakes. The climate for the coastal areas varies from hot, dry summers to cool wet winters. Inland the climate is arid with very hot, dry summers and cold, dry winters. Rainfall is relatively low across the region and can be influenced by winter fronts and tropical air masses. Streams generally flow west to the Indian Ocean. The larger river basins including the Gascoyne and Murchison drain expansive rangelands comprising of sandplains and undulating stony plains with breakaways. The shorter rivers including the Wooramell and Minilya Rivers in the north and Greenough and Chapman Rivers in the south generally drain sandy plains and loamy valleys to low alluvial floodplains near the coast. Tropical fruit growing and other agricultural uses of water depend on groundwater storage in superficial aquifers recharged by river flows, especially on the Gascoyne River. Towns like Carnarvon are threatened by floods and flood monitoring and flood warning is important for floodplain management. Other places on the Irwin and Chapman also require flood monitoring and information. Surface water flows into the Lake McLeod wetland, salinity runoff from pastoral areas and potential infrastructure developments in the Moore-Hill and Brockman River catchments are likely to require flood information. Much land in the mid west is part of the rangelands and used for pastoral production. In March 1999, the town of Moora was extensively flooded. Little flow information was available upstream of the town on the Moore River for a flood study. Three stream monitoring stations were established in the upper catchment. Minor flooding of rural land, small towns, roads and rail has occurred in the Greenough and Irwin River catchments. There is interest in evaluating the flood recurrence for these catchments. Further, the monitoring stations are telemetered for the Bureau of Meteorology to provide flood forecasts. Fire and Emergency Service Authority and the Department of Water have supported the establishment of these stream monitoring stations. The current hydrological monitoring stations for the Mid West Gascoyne Region are summarised in Table 11.1. Details on these stations can be found in Appendices C5, D5, and E5, and locations are given in Figure 11.1.

STRATEGIC REVIEW OF THE SURFACE WATER MONITORING NETWORK REPORT PILBARA REGION REVIEW

12 PILBARA REGION REVIEW

The Pilbara Region covers an area of 505 874 km2. Major river systems drain to the north west as shown in Figure 12.1. The region is bounded in the west by the Indian Ocean, east by the border between Western Australia and the Northern Territory and Salt Creek to the north. Figure 12.2 shows typical stream monitoring stations in the Pilbara region. The Pilbara Region lies within the Indian Ocean Drainage Division from the Ashburton River in the south west to Great Sandy Desert in the north east and Gibson Desert to the east. The two main physiographic zones are the coastal lowlands and the Pilbara highlands. Rugged uplands of mountains, mesas and buttes and steep gorges and broad lowland valleys containing seasonal rivers are typical features of the Pilbara Highlands. Weathering and erosion have left extremely rich deposits of iron ore synonymous with mining in the Pilbara. Rivers have worn through the upland areas creating many gorges. The Fortescue River and its tributaries have formed numerous spectacular gorges in the Karijini and Chichester National Parks and include the well know Wittenoom and Hamersley Gorges. The Pilbara is a semi arid area characterised by high temperatures, low and variable rainfall and high evaporation. It is hot and rainfall highly variable between October and April. The summer wet season receives heavy rains produced from tropical storms associated mainly with cyclonic events. Between May to September, the winter is very dry with mild to warm temperatures. Streams generally flow to the north west to the Indian Ocean. Much of the Pilbara is vegetated with low shrubby trees and many grasses. Many small shrubs are eucalypts with wiry stems or branches common to low and extremely unreliable rainfall. This sort of vegetation is broadly known as scrubland and supports pastoral production. Pilbara towns, mines and communities depend on groundwater. Irregular seasonal rainfall and surface flows replenishes this groundwater. Surface water storages like the Harding and Ophthalmia Dams capture stream flows to supplement surface water and groundwater sources. A number of borefields for town water supply are located on floodplains. Flow records from stream monitoring stations are available to estimate the flows that provide recharge to the groundwater aquifers used as water sources. Surface water monitoring stations like the Turner, Robe, Cane, Sherlock and lower Fortescue are able to provide this flow data. There are a number of environmental assets that may be affected by the activities of mining. The Fortescue Marsh is a highly valued environmental asset and monitoring of regional groundwater levels and impact on stream flows will be important. As the use of water and demand for water increases due to the expansion of mining and associated industries and growth of towns, there is an increased need to plan for water. More knowledge about surface water and groundwater will be required to assess the sustainability of surface and groundwater sources in the Pilbara. A number of surface water monitoring stations are operated for local and State flood warning purposes. These provide river height data to mining companies and other users of road and rail across rivers. River data is also provided to the BoM for their Statewide floodwarning network. Flood threat and flood recurrence warnings depend on flood monitoring. Accurate flood monitoring is important to service towns, travellers and remote communities. Public and private infrastructure has significantly increased in the Pilbara. The design of flood protection works for this infrastructure depends on reliable surface water monitoring. The current hydrological monitoring stations for the Pilbara Region are summarised in Table 12.1. Details on these can be found in Appendices C6, D6 and E6, and locations are given in Figure 12.1.

STRATEGIC REVIEW OF THE SURFACE WATER MONITORING NETWORK REPORT KIMBERLEY REGION REVIEW

13 KIMBERLEY REGION REVIEW

The Kimberley Region for the Department of Water covers an area of 417 496 km2. The major river systems are shown in Figure 13.1. The region is bounded by Salt Creek to the south-west, Lake White to the south-east and the Northern Territory border to the east. Parts of the Keep and Ord River catchments are located in the Northern Territory. One surface water monitoring station exists in the Northern Territory with others in Western Australia operated by the Northern Territory water agency. The Kimberley Region lies within the Timor Sea Drainage Division from Cape Leveque in the south west to the Keep River in the north east. Much of the landscape form is high plateau with a sandstone and igneous geology in the north; low land with rugged ranges to the east; lowland to the south west with Pindan country and incised Devonian ranges; and sandy country with high dunes in the south. A central rocky rim separates the lowland and sandy country from plateau country. It is warm and dry during the dry season from May to October and during the wet season the lowlands are often flooded. Streams generally flow north to the Timor Sea and west to the Indian Ocean. The region overall has a low and flat relief. The large river basins of the Ord and Fitzroy drain expansive savannah woodland plains and form extensive floodplains and coastal wetland complexes. Rivers in the north are short and flow through more dissected topography to a narrow coastal strip. Rivers flowing in plateau valleys can spectacularly drop hundreds of metres into the sea. Rivers to the north - west drain into a dissected coastal landscape including an extensive archipelago of coastal islands. In the north Kimberley, surface water monitoring is important for the assessment of the sustainable resource and ecologically sustainable flow for the Ord River. Use of water from the Ord River for irrigation, return irrigation water and drainage quality, river use and waterways management are important issues for the communities dependent on the Ord River. There are also ongoing water source management and protection issues for the drinking water sources of Kununurra, Wyndham and indigenous settlements. The demand for water from the Ord River catchment is foreshadowed to increase and the surface water monitoring provided data for the information in the Water Resource Management Plan, Water Use Efficiency Plan and the Ord Land and Water Management Plan. Although a small surface water dam on Arthur Creek has stored water for nearly forty years, recent records of water storages are only available. The reliability of supply for the adjoining irrigation area is uncertain. Rainfall and dam storage levels have not been well measured in this small catchment. The State and Commonwealth are progressing with regional water planning initiatives including the assessment of water futures and ecological values in northern Australia; and the establishment of the Northern Australia Land and Water Taskforce with a focus on sustainable development. The emergence of these initiatives has increased the importance in supporting the sparse surface water monitoring network and limited groundwater measurement to understand available water resources for appropriate development. Water used by the environment and importance in sustaining culture is being recognised increasingly. There is a growing expectation in the community for water to be managed for this purpose and appropriate developments in the Kimberley. Studies are currently underway to assess the sustainable yield of northern Australian catchments and provide this information to stakeholders in the north including the Northern Australia Land and Water Taskforce. In a region with very high environmental values, there is a greater expectation to manage and use the resources wisely. There is greater interest in mining in the region and the potential for impacts are recognised. Widespread fire has had a significant effect on the landscape significantly affecting pastoralists and areas with high environmental value. The changes in the landscape are likely to have altered the catchment water balance and quality significantly.

STRATEGIC REVIEW OF THE SURFACE WATER MONITORING NETWORK REPORT KIMBERLEY REGION REVIEW

Historically, surface water monitoring was collected for water resource assessment. Recently, quantity and quality monitoring has been undertaken for irrigation water use, water supply and use efficiency; and ecological flows in the lower Ord. There is little water monitoring data and information available to understand the hydrological processes at the sub basin land unit scale. As more data and information on water resources is required to understand the sustainability of ecological, social and economic systems, there will also be a need to understand the connection between surface water and groundwater. In the Cape Leveque Coast basin, there is interest in tree plantations, expanding horticulture and diversifying pastoral leases to include irrigated fodder. Storm water drainage in Broome has focused on urban drainage design for water draining to highly valued thicket complexes inland of the coastal dunes. Overall, there is limited hydrological data available for the development of public infrastructure. Roads, bridges, irrigation channels and levees have increased in this remote area and information on flooding is essential. Rural and remote communities, travellers and the Bureau of Meteorology in association with local and State Emergency depend on the surface water monitoring stations to understand the threat of river levels to communities and roads and need for evacuation measures. Flooding along the Fitzroy River is a major issue for towns and indigenous communities. Fish passage, future irrigation potential and cultural value of the river are important issues to be recognised. The current hydrological monitoring stations for the Kimberley Region are summarised in Table 13.1. The stream monitoring station density in the region is one station for every 23,700 Km2. Details on these can be found in Appendices C7, D7 and E7 and locations are shown in Figure 13.1.

In the Kimberley Region, forty eight stream monitoring stations have been closed for various reasons. There is a combined total of six hundred and eighty station years of river level data recorded. Nineteen of these stations are considered to have the potential to significantly contribute to the current and future understanding of the region’s water resource management and planning. The stream monitoring stations proposed to be re-opened are listed Table 13.3. As a priority over the next 3 years, it is proposed to establish a surface water monitoring station to measure flow from a relatively small catchment into the lower Ord floodplain. This station will support ecologically sustainable flow monitoring, sustainable yield monitoring and flood monitoring for flood studies associated with irrigation and infrastructure developments. The high flow record for Fitzroy River at Fitzroy Crossing has not been resolved. It is proposed to reopen Dwadiya (Alligator Pool) to overcome the high flow complexities that plague the Fitzroy crossing site. Part of this proposal is to close the station on the Fitzroy River Road Bridge (GNH, Fitzroy Crossing) unless it is funded by Main Roads Western Australia. Although low flow monitoring of the Fitzroy River at Fitzroy Crossing may be required for a number of current short term projects, the yield for the catchment is provided by Dimond Gorge and Fitzroy River Barrage surface water monitoring stations. Further proposals are likely, for the closed stations to be reopened for flood monitoring.

STRATEGIC REVIEW OF THE SURFACE WATER MONITORING NETWORK REPORT OTHER HYDROLOGIC MONITORING NETWORKS

14 OTHER HYDROLOGIC MONITORING NETWORKS

14.1 WORK PROPOSED BY BOM The Bureau of Meteorology has an extensive network of rainfall gauges across Australia. The extent of this network for Western Australia could benefit many if made available in conjunction with the data collected by the Department of Water. Both rainfall networks managed by the State and Commonwealth can be optimised to maximise the data collected spatially.

14.2 OTHER EMERGING NETWORKS As well as government departments with established networks, there are a number of private companies that have developed gauging networks for their own purposes which could be utilised in a State-wide monitoring network. Mining companies are one example of organisation that may have developed such a system, as these operations often benefit from having climate and surface water recording data on site. These operations are often also located in areas remote from government established systems, thereby increasing the coverage of data over the Western Australian land mass. Data from these sources are more than useful in regional analysis of water resources.

Page 96 Our Reference 1045/B1/005e

STRATEGIC REVIEW OF THE SURFACE WATER MONITORING NETWORK REPORT RECOMMENDATIONS

15 RECOMMENDATIONS

15.1 SURFACE WATER MONITORING MANAGEMENT ARRANGEMENTS Clarify the network management arrangements under the Measurement Board. Network design and management has changed from purely a network measuring the time and spatial variance of flows for representative catchments and quantity changes caused by specific land use to the management of a State surface water monitoring network for the Department’s data and information needs to manage the surface water resource as identified under the State’s water planning framework. Sustainable yield assessments will continue to require surface water monitoring sites to be used to measure spatial variance of flows for catchments representing landscape types. To manage the surface water monitoring network, policies and processes are required. For example, how should surface water monitoring sites be prioritised to meet the Department and State information needs on water resources. A process needs to be developed to prioritise site establishment and upgrades with internal data and information customers. Improve ways to coordinate management and fund the surface water monitoring network. Surface water monitoring in the State is extensive and could be made much more comprehensive through collaboration with Private and Commonwealth organisations which operate rainfall and stream monitoring sites. This collective data set could be made more widely available for increased benefit. Where possible a collaborative approach could help support the funding of key surface water monitoring stations and help spread the resource effort and allow operation of a greater number of stations. Encourage network management to find alternative ways to monitor surface water based on purpose and use of new technologies. Clarify management arrangements for the monitoring of rainfall. Ensure where required data from surface water monitoring stations collected by water users under Licence to be made available to the Department to support the surface water monitoring network.

15.2 MONITORING CHANGES TO THE SURFACE WATER MONITORING NETWORK Changes to the surface water monitoring network are not recorded. Current database systems used to collect stream flow data can be used to record this detail and support the monitoring of station purpose and the management of the network. The surface water monitoring network should be made available on the Geographical Information System. The foundation planning for the hydrological network should be included in the Geographical Information System.

15.3 EXPLORE BETTER WAYS TO MANAGE THE NETWORK Manage sites in the network to meet the data and information needs of the users. Effectively manage the network to provide an understanding of the spatial and temporal changes in surface water without compromising data needs. Adopt measures to operate sites fit for purpose under clear operating regimes without compromising the agreed data quality.

15.4 HYDROLOGICAL INDICIES Clarify the appropriate hydrological indices to be measured for the ongoing appraisal of the management of the surface water monitoring network. The discharge rating indice is based on the % of flow rate gauged.
