Fact Sheet How Dams Work
Fact sheet How dams work December 2015 In South East Queensland, our drinking water is predominantly Flood mitigation sourced from dams, which collect run-off rainwater from our catchments and store it. Our dams provide a safe, secure and At its most basic level, flood mitigation is capturing water and cost-effective water supply, as well as help to mitigate floods. then releasing it at a slower rate, with the aim of minimising river levels downstream of the dam. When dams fill, they are designed to pass the excess water into the creek or river system they are built on. What is Full Supply Level? Dam release notification service The Full Supply Level of a dam is the approved water storage level of the dam for drinking and/or irrigation purposes. Seqwater offers a free dam release notification service, which provides subscribers with notifications when gated dams For un-gated dams, if inflows result in the water level rising release water or un-gated dams are spilling. above the Full Supply Level, the water will spill out of the dam. This spilling cannot be controlled. Subscribers to Seqwater’s dam release notification service will also be notified when higher outflows are occurring from For our gated dams (Wivenhoe, Somerset and North Pine), if a spilling dam due to high inflows resulting from rainfall in the inflows result in the water level rising above the Full Supply catchment. Level, Seqwater will make controlled releases for either flood mitigation or to protect the safety of the dam. These notifications advise caution downstream due to potential hazards to people and property. -

Brisbane River Catchment Flood Study Monte Carlo Hydraulic Analysis Mitchell Smith1, Bill Syme2, Rory Nathan3
Brisbane River Catchment Flood Study Monte Carlo Hydraulic Analysis Mitchell Smith1, Bill Syme2, Rory Nathan3 1Senior Engineer, BMT WBM, Brisbane, Australia E-mail: [email protected] 2Senior Principal, BMT WBM, Brisbane, Australia 3Associate Professor, University of Melbourne, Melbourne, Australia The Brisbane River catchment is large (~15,000 km2), of which roughly half flows into Wivenhoe Dam. Rainfall across the catchment is temporally and spatially highly variable and antecedent conditions and initial dam levels significantly vary year-to-year. The influence of Wivenhoe Dam and the joint probability complexities of flows from Lockyer Creek and Bremer River rule out conventional approaches for deriving AEP flood events. To capture this variability a calibrated 1D hydraulic flood model was used to simulate 11,340 Monte Carlo flood events from downstream of Wivenhoe Dam through to Brisbane to derive AEP flood levels. An innovative process was developed to extract a representative set of 60 events grouped into 11 ensembles for the 11 AEPs from the 1 in 2 to 1 in 100,000. 1. INTRODUCTION Completed in February 2017, the Brisbane River Catchment Flood Study (BRCFS) (BMT WBM, 2017) (Aurecon, 2015) assessed the flood behaviour of the Brisbane River below Wivenhoe Dam, including the lower sections of major tributaries Lockyer Creek and the Bremer River (refer Figure 1). The study represents one of the most comprehensive hydrologic and hydraulic modelling assessments undertaken in Australia to date. The BRCFS’s major objective: The estimation of probabilistic riverine flood information for eleven Annual Exceedance Probabilities (AEPs), ranging from the 1 in 2 to the 1 in 100,000 AEP. -

Fairways Park Sketch Design LANDSCAPE CONCEPT SKETCH MASTER PLAN REPORT LOCKYER VALLEY REGIONAL COUNCIL - 4 SEPTEMBER 2019 INTRODUCTION & BACKGROUND
Fairways Park Sketch Design LANDSCAPE CONCEPT SKETCH MASTER PLAN REPORT LOCKYER VALLEY REGIONAL COUNCIL - 4 SEPTEMBER 2019 INTRODUCTION & BACKGROUND WHY ARE WE HERE Excitingly, the Lockyer Valley Regional Council is currently developing a new district park in the Hatton Vale/ Kensington Grove region. Council is currently finalising a contract to secure 14 hectares of land to develop a high-quality park in a stage approached. THE SITE LOCATION The provision of parkland and open space for recreation and sporting purposes in the rural residential area of Hatton Vale/ Kensington Grove. This future public park will facilitate the long term need for the area, as well as surrounding suburbs in the Lockyer Valley Region. In 2016 the Brightview, Glenore Grove, Hatton Vale, Kensington Grove, Lockrose, Plainland and Regency Downs area accounted for 24.3% of the Lockyer Valley Region’s population with a figure of 9,398. Based on Queensland Treasury projections there is the possibility that the land available in this region could house up to another 6,000 residents.

Erosion and Deposition During the January 2011 Lockyer Flood
Erosion, deposition and channel adjustment in Lockyer Creek, South East Queensland post the January 2011 Floods. Erosion and Deposition during the January 2011 Lockyer Flood. 1 2 3 4 Jacky Croke , Fiona Watson , Chris Thompson and Peter Todd 1 Australian Rivers Institute, Griffith University Nathan Campus, Queensland 4111 Email: [email protected] 2 Department of Environment and Resource Management, Remote Sensing Centre, Ecosciences Precinct, Dutton Park Q 4102 3 Integrated centre for Catchment Management (ICaM) Australian national University, ACT. 4 Department of Environment and Resource Management, Land Centre, Woolloongabba QLD 4102 Key Points • The Lockyer Catchment lies in an area of recognized hydrological variability. • For the January 2011 event, average peak flood transmission speeds varied from 24 kmh-1 to 2.9 kmh-1 between the upper and middle reaches. • Net erosion occurred only in the inner channel and macro-channel Banks. • Dominant form of channel adjustment was channel widening through Bank slumping and removal of within-channel Benches. Abstract This paper presents a preliminary assessment of the nature and spatial extent of erosion and deposition that occurred as a result of the January 2011 flood event in the Lockyer Valley, Queensland. Research methods include analysis of Both pre- and post-flood, high-resolution (LiDAR) digital elevation data, aerial photography, and field validation of selected sites. Results indicate that extensive channel widening (3xincrease) occurred in the steep bedrock confined river reaches of the upper valley. Dramatic examples of whole-scale re-organisation of channel morphology and geometry are apparent in these high-energy reaches. In the middle and downstream reaches, the dominant process of channel adjustment is bank slumping which has left significant and spatially widespread erosional scars. -
Brisbane River Catchment Flood Studies Settlement and Have Included Dredging and Removal of a Bar at the Mouth of the River
Managing flood risk Projects to improve flood mitigation in Brisbane and the surrounding areas have been discussed since European Brisbane River Catchment Flood Studies settlement and have included dredging and removal of a bar at the mouth of the river. Dams have an important role to play in water storage and flood mitigation in the Brisbane River catchment. Somerset and Wivenhoe Dams are the two main dams in the Brisbane River catchment. In addition to providing major water supply, they also play a role in reducing the impact of flood events. However due to the complexities of the catchment area such as its A history of living with flooding size and the amount of rainfall downstream of dams, total flood prevention is not possible. Flood Study Living with flooding is a part of life in the Brisbane River catchment and as a community we need to be informed, ready and resilient. The Queensland Government and local councils have partnered to deliver the Brisbane River Catchment We can’t prevent future floods. However, there are ways we can increase our level of preparedness and resilience to flood Flood Study (Flood Study), to investigate regional scale flooding across the Brisbane River floodplain that is caused by events across the Brisbane River floodplain. The Queensland Government and local governments are working on a long- substantial rainfall across the Brisbane River catchment. Knowledge gained from historical flood events was critical to the term plan to manage the impact of future floods and improve community safety and resilience. development of the Flood Study, which provides valuable information about the varying size and frequency of potential The Flood Study was completed in early 2017 and provides the most up-to-date flood information about the probabilities floods across the floodplain to better assess the likely impact of flood events in the future. -
