We produce stream flow management plans, local management rules and a Drought Response Plan to document the ways in which water will be managed to ensure it is shared fairly between diverters and the environment.
Stream flow management plans
These plans are prepared for Water Supply Protection Areas (WSPA) declared by the Minister for Water in catchments where the water supply is considered under stress. They are developed by an advisory committee that includes Melbourne Water, local landholders, local diverters and relevant agencies, and are approved by the government and reviewed every five years.
The plans specify:
licence conditions to protect the environment or other water users
total volume of water that can be diverted each year
trading rules for transferring water entitlements into, and within, a catchment
Notice of review outcomes for Little Yarra and Don and Woori Yallock Stream Flow Management Plans 2019
Stream Flow Management Plans (SFMPs) are used to better manage the surface water resources in catchments where the water supply is considered under stress. These water stressed catchments are declared by the Minister for Water and are known as Water Supply Protection Areas (WSPAs). The SFMPs are developed by a Ministerially appointed consultative committee to ensure water is managed and shared fairly between diverters and the environment. They are approved by the Minister and reviewed every five years. Melbourne Water has the responsibility for reviewing the plans every 5 years to determine if the plans are still meeting their objectives.
A review of the 2012 Woori Yallock and the Little Yarra and Don SFMP’s was undertaken in 2018 which recommended no amendments need to be made and as such no formal amendments or re-establishment of a Consultative Committee is needed.
Melbourne Water has prepared the following review documents assessing the effectiveness of the plans and is now seeking feedback on them from interested parties. Any comments will be considered by Melbourne Water in combination with the review outcomes.
We welcome any comments you may have on the proposal to retain the current plans and existing prescriptions. Comments can be submitted to [email protected] until Friday 31 May 2019.
Annual reports of stream flow management plans
Melbourne Water is responsible for managing approximately 1900 surface water diverters in the Yarra catchment, parts of the lower Maribyrnong River and some creeks in western catchments.
Melbourne Water is obliged under the Water Act 1989 (the Act) to develop Stream Flow Management Plans (SFMP) for certain waterways that are considered ecologically important and stressed over summer months. Seven waterways in Melbourne Water’s management district are classified as such.
Section 32C of the Act requires Melbourne Water to prepare an annual report for approved Stream Flow Management Plans. The following consolidated report and links to supportive information and annual data for each specific catchment is provided.
Local management rules and plans
Local management rules/plans are created for areas that have a level of demand lower than Water Supply Protection Area catchments. They set the rules to share water within the relevant sub-catchments.
Drought response water sharing plan
During drought or low flow conditions, licenced diverters’ access to water may be restricted or banned to protect the environment. Our Drought Response Plan/Water Sharing Plan is active at all times, and specifies how water is shared when there is not enough to meet all users’ needs.
It states river flow levels which trigger restrictions or bans, and how these are applied to different licence types. These trigger points have been developed together with stream flow management plans or local management rules/plans.
The plan is in two parts to be read in conjunction with each other:
Part A: Drought Response Plan: A Water Sharing Plan for Licenced Water Users 2016. This is the main document relevant for all diverters.
Part B: Drought Response Plan: Catchment specific Water Sharing Plans which detail specific rules for each catchment. Only one will be relevant for each diversion licence.
Diversions water outlook for Melbourne Water
Each year Melbourne Water will produce an annual water outlook providing information on the current water resource position and a forward outlook for water resources over the coming season under a range of plausible climatic scenarios. The purpose of the outlook is to try and improve the provision of water resources availability information to all water entitlement holders so that they may plan for their watering needs accordingly.
