Emergency Management of Sunwater's Dam Portfolio in The
Emergency management of SunWater’s dam portfolio in the 2010-11 Queensland floods Robert Keogh, Rob Ayre, Peter Richardson, Barry Jeppesen, Olga Kakourakis SunWater Limited SunWater owns 23 referable dams and operates a further two dams for other owners. The dams are located across Queensland from Texas and St George in the South to the Atherton Tablelands in the north to Mt Isa in the west. During the period December 2010 to February 2011 there were several significant rainfall events across Queensland. The first occurred in late December 2010, the second in mid January 2011 and third in early February 2011. Generally it was the most significant rainfall event in Queensland since the 1970’s. 22 Emergency Action Plans were activated simultaneously by SunWater. Eleven dams experienced a flood of record during the events. This paper will discuss what has been learnt from these events including the optimisation of management structures for a dam owner with a large portfolio of dams: review of O&M Manuals including the adequacy of backup systems: relationships with the State disaster management framework: the value of rigorous communication protocols: managing fear and a general lack of understanding in the community: and the value of being prepared. Keywords: Emergency Management, Floods, . In addition to the dams SunWater owns, the following 1 Background storages are managed under facility management SunWater and its subsidiary company Burnett Water Pty contracts: Ltd own 231 referable storages consisting of 18 Category 2 Glenlyon Dam – (Category 2 dam) for the Border 2 dams and 5 Category 1 dams under the Water Supply Rivers Commission (Safety and Reliability) Act 2008 and Water Act 2000. -

Sunwater Dams Sunwater Makes a Significant Contribution to the Rural, Industrial, Energy, Mining and Urban Development of Queensland by Providing Water Solutions
SunWater Dams SunWater makes a significant contribution to the rural, industrial, energy, mining and urban development of Queensland by providing water solutions. Over the past 80 years, SunWater has designed and managed the construction of 30 of Queensland’s dams, 82 weirs and barrages, 39 reservoirs and balancing storages and rural and bulk water infrastructure systems. Currently, SunWater owns and manages 19 dams in Queensland and each dam has been strategically built in existing river, stream or creek locations to serve the needs of the region. A dam is a critical component of a water supply scheme which can be made up of weirs and barrages, pumping stations, pipelines and channels, and drains. The overall scheme is designed to supply water for various purposes including town water supply, irrigation, electricity production, industrial i.e. power stations, mines, stock and groundwater supply. Water Supply Scheme Pipeline Industrial & Mining Dam Drain Pumping Station Channel Legend Balancing Storage SunWater Infrastructure Purpose of Water Supply Weir Irrigation Town Barrage Water Supply Dam Types The type of dam is defined by how the dam wall was constructed. Depending on the surrounding environment, SunWater dams can be described as one or more Scheme of the following: Pipeline Cania Dam Boondooma Dam Wuruma Dam Paradise Dam Julius Dam EMBANKMENT CONCRETE FACED MASS CONCRETE ROLLER COMPACTED MULTIPLE ARCH Industrial & Mining ROCKFILL GRAVITY CONCRETE GRAVITY CONCRETE Constructed as an Constructed as an BUTTRESS embankment of well Constructed using a Constructed in horizontal embankment of compacted Constructed as concrete compacted clay (earthfill) some large volume of layers of dryer than normal free-draining granular earth horizontal arches supported with rock on the faces (rockfill). -

Water Reporting Summary – Queensland Border Rivers Catchment
Water Reporting Summary – Queensland Border Rivers Catchment 15 March 2021 Overview • In the last 30 days, areas in the upper and lower catchment of the Queensland Border Rivers, including the catchment area of Glenlyon Dam, have received 100 to 200 mm of rainfall. Central parts of the catchment, including the catchment area for Coolmunda Dam, received 50 to 100 mm (Figure 1). As a result, the total area- average rainfall across the catchment was 93 mm over the last 30 days. This recent rainfall is in the context of the extended dry period since January 2017 with rainfall across nearly all the Queensland Border Rivers catchment being lowest on record (Figure 2). • In the last month, root zone soil moisture was average for most of the Queensland Border Rivers catchment with a few above average patches. Recent rainfall has not generated significant runoff or inflows into storages and the storage levels remain low (Figure 3). Low storage volumes have resulted in low allocations to medium priority entitlement holders in the Macintyre Brook and the Border Rivers Water Supply Schemes (Figure 4). • Announced allocations for bulk share medium priority entitlements in the Macintyre Brook Water Supply Scheme were 12% as at 1 September 2020 which, for this time of year, is the second lowest in the last ten years. For the Border Rivers Water Supply Scheme, the announced allocation equivalent for medium priority allocations was 4% (as at 30 June 2020) which, for the time of year, is the lowest in the last ten years (Table 1).
