It is published on or by June 30 each year.

About the seasonal watering plan
The seasonal watering plan is a statewide plan that guides decisions about delivering water for the environment in Victoria. It outlines how water for the environment is likely to be used across the state under different climate scenarios and tells the VEWH’s program partners, Traditional Owners, stakeholders and communities what to expect during the water year.
The plan is developed by the VEWH in close partnership with waterway managers and Traditional Owners in a planning process that is informed by scientific evidence, biocultural knowledge, local inputs and on-ground evaluation. Waterway managers engage extensively with their communities including Traditional Owners, storage managers, land managers, and scientists during the process.
Seasonal watering statements
Seasonal watering statements communicate decisions about environmental watering activities as water availability scenarios occur through the year and authorise waterway managers to order and deliver water in the water holdings on behalf of the VEWH to achieve environmental outcomes.
Changes to the seasonal watering plan
Under the Victorian Water Act 1989, the VEWH can only authorise use of water for the environment where it is consistent with a seasonal watering plan. This provides transparency about what environmental watering is planned.
To enable flexibility to changing conditions, under the Act we can vary sections of a seasonal watering plan.
This could be to incorporate new knowledge or to adapt to any circumstances not identified by 30 June.
What changes don’t need a formal variation
Changes that don't require a variation to the seasonal watering plan include:
- minor operational adjustments to specific watering actions
- using the water to manage environmental emergencies
- using small volumes of environmental water for technical investigations
- facilitating water deliveries held by other water holders for downstream objectives.
The planning process
Each year, seasonal watering proposals are submitted to the VEWH for consideration. They set out the scope of potential watering actions for the year ahead and may be prepared by:
- waterway managers, such as catchment management authorities or Melbourne Water
- Traditional Owner groups
- partnerships between waterway managers and Traditional Owners.
Proposals may draw on environmental flow studies, environmental water management plans, regional waterway strategies, Traditional Owner knowledge and planning sources and advice from technical experts, and local communities.
The VEWH reviews each proposal and includes accepted watering actions in the seasonal watering plan.
Planning for seasonal variability
Objectives for water for the environment differ depending on seasonal conditions – drought, dry, average or wet to very wet seasons, and water availability.
The potential environmental watering under each scenario is included in the scenario planning section of system sections in the seasonal watering plan.
