Preventing shore erosion

May 22, 2018

Goulburn-Murray Water is working to prevent shore erosion caused by waves at Lake Mulwala.

Goulburn-Murray Water is taking additional steps to stop significant wave erosion at Lake Mulwala.

The authority has made repeated attempts to prevent erosion at the popular lake’s foreshore, but the problem has persisted.

Another tranche of foreshore erosion protection efforts will begin this week, marking the authority’s second stage of mitigation measures.

The initial stage along Bank St, Yarrawonga, was done in 2015.

This second stage will take place along River Rd during a planned drawdown of Lake Mulwala, from this month to July.

G-MW customer infrastructure and assets manager Marc Lon Ho Kee said the lake foreshore at Yarrawonga had been subject to significant erosion in the past, mainly due to wave action.

‘‘Despite repeated attempts using rock beaching and other techniques, erosion has continued to be a concern for the foreshore area — this project will protect the foreshore and safeguard from further environmental damage,’’ he said.

‘‘We’re creating a long-term solution that will reduce maintenance costs, ensure the ongoing enjoyment and safety of recreational users, and protect water quality and environmental values.’’

An estimated 160m of works began yesterday along River Rd in Yarrawonga. A shared gravel path is being be fenced off as part of the works.

G-MW manages the foreshore of Lake Mulwala for the Murray-Darling Basin Authority.

Mr Lon Ho Kee said the works aligned with the authority’s management plan for the lake area.

‘‘While the main purpose of Lake Mulwala is to provide water to NSW and Victorian farmers, we recognise it’s a popular spot for recreational activities such as fishing, boating, walking and bird and wild-life watching,’’ he said.
