Natural Flows Reviving Devilbend Reservoir

Monday 25 September, 2017

For the first time in 61 years, water is again flowing into Devilbend Reservoir via its original creek watercourse. A water diversion project, completed last year by Parks Victoria staff, will see up to 17 million litres a day flowing into the reservoir during peak flow times. This volume of water will see a substantial rise in the reservoir, ensuring its sustainability over summer months and climate changes.

The reservoir is the largest and most significant water body on the peninsula, and this seasonal flow will boost its general health and biodiversity and create better habitats for bird and fish species.

Over 150 bird species have been recorded at the reservoir, including the rare Blue Billed duck and the White Bellied Sea Eagle. It’s also a seasonal home to many migratory birds. The inflow will also benefit the Native Dwarf Galaxias fish which was recently re-discovered in the catch drain.

Ranger Team leader with Parks Victoria Luke Ashford is involved with the project and has been watching the results of the returned natural water flow.

“Returning the natural flow of water to the original creek bed is already killing off introduced weeds and plants and promoting the return of native species. It’s a healthy outcome for both the reservoir and its natural waterway.”

The diversion, managed in partnership with Melbourne Water, involved extensive hydrological and excavation work to reactive the creek. It will operate over winter months taking a portion of the flow from the catch drain and diverting it into the Reservoir. The system is designed to ensure sustainable flows continue along Devilbend Creek whilst maintaining the aquatic health and habitat of Devilbend Natural Features Reserve.

“The partnership with Melbourne Water and the local community will allow us to remotely monitor and control the flow rates and water quality running into the reservoir, ensuring a successful biodiversity outcome,” says Georgia Kerr, Area Chief Ranger with Parks Victoria.
