Water Quality Alert - Brimpaen Area
Reason: Water Quality
Starting: 11.40 am, 13 January 2023
Customers with a rural supply in the Brimpaen, Laharum, Noradjuha, Natimuk and Wartook Valley areas may be experiencing discoloured water. GWMWater is monitoring and managing storages to improve water quality in this area.
Water is darker than normal in Lake Wartook due to high rainfall and flooding last year. With high summer demand on the system, the Brimpaen storages are being filled with coloured water from Wartook and the channel system. Water sampling is showing water quality flowing into the storages is improving. We anticipate the water quality in the supply system to improve over the coming weeks.

Blackwater Monitoring - Murray River
Reason: Blackwater in the Murray River
GWMWater filters water on our Murray River Pumping Systems however, this does not improve water quality during blackwater events. Some regulated towns supplies also have a minor level of treatment which has little impact on blackwater.
GWMWater operational staff will continue to manage treatment processes where possible, and flush pipes to help relieve some of the effects of blackwater. We expect water quality issues to continue for several weeks.
Customers can contact us 24/7 on 1800 188 586 to discuss any water quality concerns or report any sudden change in water quality.
GWMWater will provide further information to customers if the situation changes or if any actions need to be taken.

LAST UPDATEDRocklands Reservoir, located on the Glenelg River, is GWMWater's largest reservoir. It was originally constructed to supply the now decommissioned Wimmera-Mallee Domestic and Stock channel system. In more recent years it has an important role to play in the region as a recreational destination. A unique feature of Rocklands Reservoir is that all entitlement holders, including the environment, are eligible for water supplies from the reservoir.
The reservoir also has six location buoys on the water for each of the six main camp grounds. These buoys help boats locate their position on the lake.
