Inside, you Environmental Water Holder (VEWH) and its partners in the will hear from our partners – catchment management authorities environmental watering program. and Melbourne Water – as they recount the work they have undertaken, including the achievements, challenges and lessons This, our third year of operation, saw a significant leap in the scale learned in 19 Victorian waterway systems. of our activities. The environmental watering program scoped 222 priority watering actions across Victoria – almost double As always, I would like to recognise the ongoing time and effort of the previous year1. We were able to deliver more than 800,000 all our program partners this year, including waterway managers, megalitres (ML) of water2, to support environmental values for storage managers, and land managers. I would also like to 145 river reaches and wetlands. This resulted in the full or partial recognise and thank the CEWH and office, our partners at the achievement of 82 percent of the identified actions for 2013-14.

We were able to water more sites this year because we had access to more water, including environmental water carried over, water purchased with our partners and increased availability of water from the Commonwealth Environmental Water Holder (CEWH). We are continuing to improve our processes and address Denis Flett knowledge gaps. Flexible and adaptive environmental water management is already contributing to the improved Chairperson environmental health of waterways. We are able to use environmental water where and when it is most needed. 1 The environmental watering program scoped 122 priority watering actions for 2012-13. 2 809,515 ML was delivered from VEWH accounts in 2013-14 (compared to 437,242 ML in 2012-13). In addition, 358,316 ML was delivered to Victorian waterways from other sources, totalling 1,167,830 ML delivered in 2013-14. 2 | Victorian Environmental Water Holder Sandford fish ladder at Glenelg River, by Stephen Ryan, Glenelg Hopkins CMA Reflections – Environmental watering in Victoria 2013-14 | 3 The role of the Victorian Environmental The importance of environmental water Water Holder Environmental water supports the rich and diverse values of Victoria’s waterways.

Waterways are also important in connecting communities. managing the State’s environmental water entitlements (Water They support a range of social values – including cultural heritage Holdings). The vision which guides the long-term management of values such as traditional medicinal plants and scar trees, and environmental water by the VEWH is: recreational activities including boating, fishing and camping. Environmental watering for healthy waterways Many of these environmental and social values also support economic values, including through tourism and ensuring good • Healthy and resilient waterways with restored watering water quality for irrigation. patterns that sustain a more natural level of biodiversity.

In undertaking its mission, the VEWH: • makes decisions on the most effective use of the Water Holdings, including use, carryover and trade • liaises with other water holders to ensure coordinated use of all sources of environmental water • authorises waterway managers to implement watering decisions • works with storage managers to coordinate and maximise environmental outcomes from the delivery of all water • commissions targeted projects to demonstrate ecological outcomes of environmental watering at key sites • publicly communicates environmental watering decisions and outcomes. 4 | Victorian Environmental Water Holder Benefits of environmental flows 1 Stimulate fish breeding and allow fish to move within the system 2 Provide habitat for waterbirds and stimulate breeding 3 Move sediment and maintain channel shape 4 Improve water quality 5 Provide habitat for frogs 6 Regenerate instream vegetation 7 Trigger plants to seed or germinate 8 Allow movement of carbon (eg. leaf litter between floodplains and rivers) 9 Flush out salt from riverbanks and floodplains 10 Restore groundwater supplies 11 Provide social, recreational and tourism opportunities Reflections – Environmental watering in Victoria 2013-14 | 5 Highlights of environmental watering Figure 1 Achievement of priority watering actions in 2013-14 In 2013-14, over
