Water storage information

Rainfall

Rainfall received at Malmsbury Reservoir is captured by Coliban Water. 

The data is provided to the Bureau of Meteorology, contributing to their network of weather stations.

Inflows

Inflows to our storages on the Coliban River, namely the Upper Coliban, Lauriston and Malmsbury Reservoirs, are calculated based on the change in water level, evaporation, diversions and releases. 

Lake Eppalock inflows are calculated by Goulburn-Murray Water.

Measured inflow data is also available from gauging stations on the Coliban River, Little Coliban River and Kangaroo Creek from the Bureau of Meteorology website.

Coliban Water manages the Upper Coliban, Lauriston and Malmsbury Reservoirs and often report on the combined water in storage in the reservoirs.
