Arrangements for Flood Warning Services in Victoria
February 2001



6. Regional Level Responsibilities

Catchment Management Authorities

Catchment Management Authorities (CMAs) will support the provision of flood warning services by assisting with the regional planning and coordination of new and upgraded flood warning systems, through their regional floodplain management strategy and local floodplain management plans, and in consultation with the VFWCC. CMAs as the regional floodplain management authority, should identify the needs and benefits for improved flood warning systems and liaise with local government in an effort to gain local support and commitment.

CMAs may contribute to capital and ongoing costs of flood warning systems where there is a benefit to their activities. The extent of this role is subject to negotiation between CMAs, NRE, RWAs, and Local Government. The BoM will provide advice where required.

In specific cases of regional significance CMAs may contribute to the flood inundation mapping component of the flood warning systems.

CMAs will coordinate the monitoring of significant floods within their region and in special cases (e.g. rural areas) collect real event flood data such as flood extent, flood levels and flood damages etc (Section 4.12).

Rural Water Authorities

Rural Water Authorities (RWAs) are responsible for the installation, operation and maintenance of data collection networks, for the purpose of operating water supply storages and infrastructure, monitoring dam safety, water extractions, environmental flows and water releases. This will include networks located upstream of any structure as well as downstream to monitor the impact of operational decisions. These networks will be operated to support efficient real time access to data by the BoM and other agencies involved in flood prediction at no cost, and supported in accordance with the roles and responsibilities set out for flood warning data collection networks.

In circumstances where operational releases from storages are likely to cause significant inconvenience below minor flood level, RWAs will develop and implement formal arrangements to advise the community of the proposed releases. During periods of expected flooding or flooding RWAs will provide water supply storage operation information to agencies involved in flood warning.

Melbourne Water

Melbourne Water (MW) is responsible for the installation, operation and maintenance of data collection networks for the purpose of drainage management and flood warning for Greater Melbourne. For the Greater Melbourne area, MW has responsibility for flood prediction on the main streams. MW prepares flood warnings and disseminates these warnings to the Greater Melbourne community through the BoM. MW may also provide direct advice to the relevant Council for cases of local flooding.

For the urban area of Greater Melbourne where flash flooding can occur across a number of Local Government boundaries, MW, where appropriate, may be able to provide flash flood assistance to Local Government. This assistance may include providing stream level predictions where possible which are presented in flood warnings prepared by MW but issued through the BoM.
