Rocklands Reservoir
The Rocklands Reservoir, a water reservoir, is created by a major ungated concrete-walled gravity dam with embankment sections across the Glenelg River in the Wimmera region of Victoria, Australia. It is the largest reservoir within the Grampians–Wimmera–Mallee Water supply system. Originally constructed to supply the Wimmera-Mallee Domestic and Stock channel system, water held by Rocklands Reservoir is now used for many different purposes. A unique feature of Rocklands Reservoir is that all entitlement holders, including the environment, are able to be supplied with water from the reservoir.
