The group in charge of water quality of environmentally-significant wetlands near Busselton, in south-west Western Australia, has a new plan.

The Vasse Taskforce exists to fix the declining health of the Vasse Wonnerup Wetlands, set up in the wake of a number of mass fish deaths.

Kath Lynch from WA’s Department of Water said the group has a new strategy, which includes about 30 different projects to further improve water quality and waterways management.

The strategy was endorsed last week.

“The key waterways that we're looking at is the Vasse Wonnerup Wetlands, the Lower Vasse River, the Toby Inlet, plus the Geographe waterways and also we're looking at the rural drainage system as well,” Ms Lynch told reporters this week.

“So it's very much about the whole catchment.

“You know ultimately all those waterways flow into Geographe Bay, which is ultimately what we're really trying to protect.”

She said the initiative would work to the strategy over the next three years.

“That's the action plan that we've put together as a taskforce for the different elements moving forwards to improve water quality and waterways management,” she said.

“There's about 30 different projects in that from a whole range of different government agencies, so endorsing that was a really big step forward.”
