Weekly Report 10 March 2021
River Murray Weekly Report For the week ending Wednesday, 10 March 2021 Trim Ref: D21/6430 Rainfall and inflows The southern Basin recorded little rainfall this week (Map 1). In the northern Basin the highest rainfall totals were observed in Krui Plains and Pindari Dam in northeast NSW, recording 63 mm and 55 mm respectively. Moderate rainfall totals are forecast for the upper Murray and north-east Basin this week. Map 1: Murray-Darling Basin rainfall for the week ending 3 March 2021. Source: Bureau of Meteorology. Dry conditions across the southern Basin saw streamflows continue to recede. Further specific information about flows at key locations can be found at the MDBA’s River Murray data webpage. Up-to-date river data for sites in the upper Murray can also be found on BoM’s website and in the Murray River Basin Daily River Report at the WaterNSW website. Subscribe to the River Murray Weekly Report River Data website Water in Storages River Murray Weekly Report River operations • Water quality has improved downstream of Hume • River Murray Flows may vary at Easter • Red alert levels for blue-green algae at Lake Victoria, Sunraysia and Lower Darling Easter Flows With the busy Easter and school holiday period approaching in early April, river users are reminded that River Murray levels from Hume Dam to South Australia depend on a range of factors including weather and system demands. Depending on the location along the system, flows are likely to remain around current levels under dry conditions but will ease between now and the Easter and school holiday period under wetter scenarios where rainfall generates inflows or supresses irrigation demands. -

Waternsw Second Submission to the Independent Expert Panel
PO Box 398, Parramatta NSW 2134 Level 14, 169 Macquarie Street Parramatta NSW 2150 www.waternsw.com.au ABN 21 147 934 787 SUBMISSION TO THE INDEPENDENT EXPERT PANEL FOR MINING IN THE CATCHMENT March 2019 The three key issues raised in this submission are outlined below, with a summary of the associated recommendations. 1. Environmental consequences There is now strong evidence that the environmental consequences from mining in the Special Areas are greater than predicted when the mining was proposed and approved. Importantly, some of these environmental consequences have caused (or are likely to cause) breaches of conditions in the relevant development consents, including performance criteria to protect watercourses and Sydney’s drinking water catchment. Recommendations 1. Restrictions on future mining at Dendrobium and Metropolitan 2. Performance criteria of “negligible” quantified for all ‘significant’ natural features 3. Less reliance on remediation as a mitigation measure 4. Estimates on catchment water loss and advice on appropriate thresholds, and 5. A risk assessment approach based on thresholds for catchment water loss. 2. Monitoring and analysis While the level of monitoring and analysis of mining impacts has improved substantially in recent years, there are still considerable improvements that need to be made to ensure that decision-makers have an adequate understanding about current and likely impacts and consequences. WaterNSW undertakes routine reviews of its monitoring network for our purposes, however the mining companies should generally bear the cost of undertaking additional monitoring and analysis associated with mining impacts. Recommendations 1. Strengthened baseline and post-mining monitoring funded by mining companies 2. Development of analysis and modelling standards 3. -

Raising Warragamba Dam
Resilient Valley, Resilient Communities Hawkesbury-Nepean Valley Flood Risk Management Strategy Frequently asked questions Raising Warragamba Dam Why raise Warragamba Dam for flood mitigation? Warragamba Dam is on the Warragamba River - one of the major tributaries to the Hawkesbury-Nepean River. Flows from the large Warragamba Catchment are involved in all major regional floods that pose the greatest risk to life and property. Warragamba is Sydney’s largest water storage dam and provides around 80% of current storage. The dam is not built or operated to manage or mitigate floods. In developing the Flood Strategy, a range of options were investigated to use or modify Warragamba Dam to provide flood mitigation. It was found that raising the dam wall by around 14 metres is the infrastructure option with the highest benefit – significantly reducing the risk to life downstream, and reducing flood damages by around 75% on average while balancing the impacts on the upstream environment. It would significantly reduce the risk to life and property, including the worst floods on record, and increase the certainty of time for people to evacuate. How would a raised Warragamba Dam mitigate floods? The raised Warragamba Dam wall would mitigate floods by creating ‘airspace’ in a dedicated flood mitigation zone around 14 metres above the current full water supply level. This flood mitigation zone behind the wall would capture and temporarily hold back floodwaters coming from the large Warragamba Catchment. After the flood peak, the floodwaters would be released in a controlled way – reducing flood levels downstream and potentially devastating impacts on downstream communities. -

The primary aim of this project is to scope management options to reduce and mitigate the impacts of sewage overflows in the Sydney coastal region, based on a review of international best practice and historical trends in sewage management in Sydney. The topic was chosen as the 15 member councils of the Sydney Coastal Councils Group nominated sewage overflows as their common issue of greatest concern. This review was prepared as a supporting document to the Issues Paper on Sewage overflows management in the Sydney coastal region.
