Waterways Local Update 2014-15 Melbourne Water’s work to improve waterways and provide flood protection in the City of Maroondah. 11 km weed control along waterways $45,750 for council to improve stormwater reuse 13 volunteers provided us with rainfall data Melbourne Water is responsible for 8,400 km of rivers and creeks, 428 wetland treatment systems and more than 1,400 km of regional drainage systems in the Port Phillip and Westernport region. This work is funded by the Waterways and Drainage Charge, which is paid by property owners and collected by water retailers on our behalf. Within your local area, Melbourne Water cares for the following waterways: • Dandenong Creek • Brushy Creek • Mullum Mullum Creek Healthy waterways Maintenance Each year we create and maintain healthy waterways by removing litter, debris and excess sediment. We remove and spray weeds, cut grass and plant native trees and shrubs. What we have done Why 11 km weed control Introduced and noxious weeds can choke waterways and take over from plants which provide healthy habitats for birds and animals 415 m3 sediment/silt removal Silt and sediment is removed for drainage and flood protection and to prevent pollution building up in our waterways. Excess silt and sediment in waterways and wetlands can also impact on habitat for native plants and animals 56 m3 litter/debris removal Litter can have devastating consequences for native animals and plants living in waterways. Debris such a leaves and grass cuttings can restrict the flow of water causing a flooding risk and changing the habitat for platypus and fish Worked with Council to upgrade habitat along Dandenong Creek To control erosion and increase diversity of indigenous plant species for improved animal habitat Waterways Local Update 2014 –15 1 Stormwater We work closely with Council and local communities to better manage stormwater to protect the environment, provide alternative water sources and improve the stormwater that flows into local waterways. What we have done Why Funded installation of raingardens in Kandra Street Raingardens are self-watering, low maintenance gardens designed to protect our rivers and creeks. Raingardens capture stormwater that runs off hard surfaces after it rains, reducing the quantity and improving the stormwater that flows into local waterways Through our Living Rivers program, we have worked with Council and contributed $45,750 to projects that assist waterway health and create sustainable stormwater management solutions in your area. Find out more at melbournewater.com.au/livingrivers Monitoring and research We regularly undertake extensive monitoring, investigations and research to help us better understand how we can improve local waterways. What we have done Why Undertook monthly water quality monitoring at one site within your area. These tests measure: Our water quality monitoring program is designed to assess broad-scale, long-term trends in water quality (typically over eight to 10 years). We use this data to help identify pollution sources and inform the community about local water quality • water temperature • dissolved oxygen • salinity (conductivity) • pH level • nutrients (nitrate, nitrite, ammonia, Kjeldahl nitrogen, soluble reactive phosphorus and total phosphorus) • indicators of faecal contamination (E. coli) • metals (arsenic, cadmium, chromium, copper, lead, nickel and zinc) Waterways Local Update 2014 –15 2 Planning for future development We plan for future development to ensure growing communities do not threaten local waterways. We also advise and assist new developments to ensure they do not increase flood risk. What we have done Why 259 referrals for land subdivisions reviewed To ensure proposed land subdivisions meet current standards for drainage and stormwater quality 9 development applications reviewed To make sure that growing communities don’t increase flood risk 48 flood information requests reviewed To provide flood information to property owners and people interested in purchasing or redeveloping property 17 applications for works near Melbourne Water assets and works such as bridges, shared pathways and jetties reviewed To ensure waterways, and the plants and animals that live there, are protected from the potential impacts of building works 5 stormwater connection applications reviewed To ensure waterways and the plants and animals that live there, are protected from the potential impacts of construction works Waterways Local Update 2014 –15 3 Flood protection While floods are natural and we can’t stop them all from occurring, we aim to minimise the damage they cause to people, places and communities. We manage the regional drainage system and work with Council, the Victorian State Emergency Service, the Bureau of Meteorology, property owners and developers to make sure flood information is up to date, provide flood warning services, and prepare flood response plans. We also identify and construct new flood protection projects in areas with the greatest need. What we have done Why Consulted with councils and communities to develop a draft strategy to guide future flood management across the Port Phillip and Westernport region Although we cannot prevent floods from occurring, we can work together to manage the risks and minimise the damage and disruption they cause to people, places and communities We operate and maintain two monitoring stations in your area to collect real-time information such as rainfall and water levels This data helps us understand rainfall patterns, plan responses to droughts and floods and make sure rivers and creeks have enough water to support local wildlife Flood mapping completed in Kilsyth West To update our knowledge of flooding, better manage drains, assess flood risks in the catchment and assist with planning scheme overlays Commenced a flood mitigation project at Lincoln Road Drain (Rear of Gretel Court to Rear of Leanne Crescent, Croydon) To provide a greater level of flood protection and reduce flood risk for local properties Met with Council and the State Emergency Service to review implementation of the Flood Management plan To ensure on-going coordination and collaboration in managing flood risks 13 volunteers in your area provide us with rainfall data by recording information from a rain gauge in their backyard. These figures, together with data from our automated gauges, provides us with valuable rainfall information.

If you’d like more information about funding opportunities please call 131 722 or email river.health@melbournewater.com.au Funding provided Grant $385 Stream Frontage Management Funding for private land owners and managers for works that protect or enhance riverbanks, such as weed control, fencing and planting native trees $1,100 Community Grants Funding for volunteer and community groups for works that protect or enhance riverbanks on public land and raise awareness, training and education to protect local waterways Throughout the year we also worked with the local community on several events and initiatives. Who we worked with What we did 1st Croydon Scouts Provided a Community Macroinvertebrate Monitoring Program 3rd Croydon Scouts Provided training, materials and ongoing support for macroinvertebrate monitoring in the Yarra River Waterwatch is a citizen science program that encourages communities to monitor platypus, frogs and waterbugs as well as the water quality of their local river or creeks. We empower our volunteers to collect data, protect the waterways environment and share their knowledge. Visit melbournewater.com.au/waterwatch or call 131 722 to find out more.
