The lakes, once disused water storage lagoons at the Merrigum Water Treatment Plant, have been transformed into a popular fishing spot for locals and visitors alike.
The catch-and-release-only lakes now teem with hundreds of Murray cod and yellow perch, including several 'monster' cod measuring over 1.2 metres.
Over the past two seasons, the Murray cod have been breeding successfully, creating a self-sustaining ecosystem.
GVW managing director Steve Capewell said it was fantastic to see the lakes being enjoyed by local fishing groups and visitors alike and they look forward to growing it more in the future.
“Dunyak Moira is testament to what you can achieve when you look outside the box at opportunities for retired public infrastructure, and this is something unique and special for the Merrigum community,” he said.
Since its official opening on October 11, 2023, Dunyak Moira has attracted more than 500 visitors.
The site has also become a hub for sustainability and biodiversity.
Duck nesting boxes have seen 48 clutches hatch, while about 8000 shrubs, small trees and aquatic species have been planted to revegetate the area.
Burnanga Indigenous Fishing Club president Corey Walker praised the project's success.
“It’s been a great success with many community members enjoying the benefits of recreational fishing activities, following the hard work of GV Water and the Burnanga Indigenous Fishing Club to have a shared vision to create and establish an ecosystem for native fish populations,” he said.
The management committee is currently working on completing an accessible fishing pontoon, supported by a grant from the Victorian Government's Recreational Values program.
It is also exploring options for future amenities and potential community events.
The lakes are open on Fridays, Saturdays and Sundays from 7am to 8pm during daylight saving hours.
