About Waranga Basin

Waranga Basin is an important off-river storage, where water is diverted from the Goulburn River at Goulburn Weir, via the Stuart Murray Canal and Cattanach Canal.

The Basin also has a small catchment area of its own with a capacity of 432,360 ML and is one of the largest storages in the Goulburn System. 

History 

The first stage of water storage commenced in 1905. The embankment was completed in 1908, using picks, shovels and horse drawn scoops, and at the time of construction was described as the largest project of its kind in the world, with an embankment height of 8m and a length of 7km.

Between 1915 and 1921, the embankment was raised to a maximum height of 12.2m, and the puddle clay core wall and rock beaching was extended to the new crest level. The storage inundated the original Echuca and Waranga Trust channel that had been constructed to convey water from the Goulburn River to the Murray at Echuca.

Operations

The water stored in Waranga Basin supplies the Central Goulburn, Rochester and Pyramid-Boort irrigation areas across northern Victoria. Supplies to the Rochester and Pyramid-Boort areas occur via the 180 km long Waranga Western Channel.

The volume of water in store is mainly regulated. All discharges take place through channel outlets. The Major Outlet has a discharge capacity of 4,200 ML/day, and the Minor Outlet discharge capacity is 1,850 ML/day.

In the 2006/2007 Irrigation Season, the Goulburn System experienced the worst drought on record.  Water available to Goulburn-Murray Water customers was approximately half that available in the previous ‘worst' year which occurred in 2002/2003.

Normally, only about three-quarters of Waranga Basin's capacity of 432,360 ML can be used by gravity flow from the Basin's two outlets. In April 2009 as well as 2002, 2007 and 2008, Goulburn-Murray Water pumped up to 90,000 ML of water from below the normal minimum operating level in Waranga Basin to assist drought stricken farmers in the Goulburn Irrigation System. Pumping also occurred in 1926. The 2009 operation is estimated to have cost around $2 million. This project was a part of a range of measures Goulburn-Murray Water implemented to maximise the amount of water available for use in such a dry year.

Location

Waranga Basin is located between the Goulburn and Campaspe River basins, approximately 8 km north-east of Rushworth.

Further Information

The fourth largest inland waterway in Victoria, Waranga Basin is located between the Goulburn and Campaspe River basins, 8 km north-east of Rushworth and 12 km south-west of Tatura.

The basin was formed on the site of a natural wetland formerly known as Waranga or Gunn's Swamp. It is a family-friendly destination and one of the best kept secrets in Victoria.

Today the basin supplies irrigation and stock and domestic water to entitlement holders in the north and west of the state.

Waranga Basin is one of 23 lakes, dams and reservoirs managed by GMW to capture, store and deliver 70% of Victoria's stored water across the region.

Facilities along the reservoir's foreshore include the popular Lake Waranga Caravan Park and Holiday Camp, picnic areas and public boat ramps.

You can explore the foreshore on one of the many trails where you're sure to find a secluded spot to sit and relax, or head out birdwatching kite flying or cycling. Waranga basin is also popular for boating and on-water activities. 

Please Remember

  • No camping or fires allowed on GMW foreshore land.
  • Confine vehicles and motor bikes to formed public roads.
  • Take your rubbish home.

Waranga Basin is a beautiful natural resource. You can help care for the lake so it can be enjoyed now and into the future.

  • camping and campfires are prohibited in GMW reserves and on foreshore and lakebed areas
  • electric barbecues are available at some reserves (see map below)
  • refer to your local council for landfill services and consider the environment when disposing of your litter. Penalties apply for illegal dumping of rubbish
  • don’t take plants from the foreshore, or bring any in
  • don’t feed the animals or wildlife, or interfere with their habitats
  • boat wash can cause erosion, keep to 5 knots within 50 metres of the water’s edge
  • vehicles and trail bikes are only allowed on public roads within the reserve
  • all vehicles and trail bikes must be registered and users must be licenced
  • keep the waterway healthy by not using soap, toothpaste or detergent in the lake
  • dogs must be on a lead and/or under control at all times and aren’t allowed in the lake. Please clean up after your pets.

GMW's customers use the water in our storages to produce food and fibre, supply towns and businesses, and protect and improve waterway health.

Visitors need to be conscious of potential hazards and consider their own safety and the safety of other users at all times. Water levels (high or low) can prompt increased safety measures, and changes to access for recreational areas and boating.

Safety information and  alerts will be signposted at public areas and boat ramps.

Find out more about   current water level information.

At times, the level of blue-green algae in storages can exceed safe limits. When this happens you should avoid direct contact with the water as the algae can cause;

  • skin rashes
  • itchiness
  • sore eyes, ears and nose
  • nausea.

If unsafe levels occur, warning signs will be positioned at major recreational areas.

Online Blue-green algae warnings are available or by calling the 24 hour GMW blue-green algae hotline on  (03) 5826 3785.

Camping is not allowed on the foreshore of the lake but there are a range of accommodation options through out the region.

Find out more on the  Lake Waranga Caravan park website or the  Parks Victoria website.

GMW’s lakes, dams and reservoirs are ideal places for events. Find out more about hosting an  event at one of our storages.
