About the project
The project, now complete, improved the efficiency of Lake Brewster for water storage on the Lachlan River in NSW. Lake Brewster has been divided into four management units: inlet wetland; two lake cells; and outlet wetland and was a joint initiative between regional natural resource managers, water delivery managers and water users of the Lachlan River. The project has reduced evaporative losses and at the same time provided environmental benefits for Lake Brewster and the downstream riverine ecosystem. This is an example of all stakeholders working together for a more sustainable, efficient and secure river operation.
The project consisted of:
- construction of a main dividing embankment to create two separate water storage cells
- deepening of the outlet channel to increase discharge from the storage at low levels
- creation of three spillways to pass inflows into the main storage cell from the inflow wetland
- construction of an embankment for the creation of an inflow wetland
- construction of a number of regulators to control the flow of water into and out of the wetlands and storage cells.
The project has advanced the National Water Initiative objective of providing greater certainty of management of water resources for both industry and the environment.
Water Smart Australia projects are funded by the Australian Government's Water for the Future initiative.
