Parks Victoria has completed construction on a new weir at Lake Natimuk, enhancing flood prevention and recreational opportunities in the state's west.

Located on the lake's northwest shoreline, the new weir maintains the same water levels as its predecessor. The structure can safely release excess flows into Lake Wyn Wyn Wildlife Reserve following periods of heavy rain or flood.

The network of wetlands around Natimuk has immense environmental significance as a habitat for birds, particularly waders. During periods of elevated water levels, the lake has historically transformed into a popular destination for camping, swimming, and fishing. 

Initiated in 2016, the project faced a temporary pause to assess environmental impacts to the lake, secure necessary approvals and acquire funding.

Throughout this process, Parks Victoria engaged with more than 900 community members who shared overwhelming support for the project. The weir's design and height (114.7 Australian Height Datum) were developed in close collaboration with the Natimuk Lake Foreshore Committee.

Parks Victoria also worked with the Barengi Gadjin Land Council Aboriginal Corporation to ensure the new weir adheres to cultural heritage management and protection standards, including remediation of the surrounding area following works.

Lake Natimuk – spanning approximately 310 hectares – is typical of Australia's inland lakes, experiencing natural fluctuations between dry and flooded periods. The lake's catchment area comes from farmland south of Natimuk. 

This project was funded under the Asset Regeneration Program, a $24.76 million investment by the Victorian Government to remove unsafe infrastructure and to repair or replace assets across the Parks Victoria estate.

Quotes attributable to Michael Smith, Parks Victoria District Manager: 

“Lake Natimuk and Natimuk Creek Lake Reserve is part of the Natimuk-Douglas saline wetland system, which is of immense environmental value, and of particular importance to shallow-water wading birds. Lake Natimuk is also a much-loved area of natural beauty and recreation for the local community.”

“We’re pleased to deliver this new community asset, which has been built to last and will safely divert water when required, while ensuring environmental and cultural values are protected.”
