Lake Buffalo upgrade
Between April and June 2017, Goulburn-Murray Water (GMW) will upgrade Lake Buffalo’s spillway gates to bring them in line with current Australian dam design and construction standards.
The $3 million project, funded by GMW, will strengthen the spillway gates and increase their stability, ensuring the long-term reliable supply of water to our customers and the safety of downstream communities.
The two-year upgrade involves replacing all three existing flood gate lifting hoists and refurbishing the spillway gates. Last year, work was completed on Gate 1. This year, GMW expects to refurbish Gates 2 and 3 and complete the project.
The work involves drawing down Lake Buffalo to about half its capacity. This has been timed to not impact on water delivery or recreation. It also requires the temporary closure or part-closure of the section of Buffalo River Rd traversing the dam wall. For these details and further information about our Lake Buffalo upgrade, refer to our fact sheet.

Water Security for Wangaratta project
In 2013, the Victorian Government announced $1 million for the Water Security for Wangaratta Project and appointed a Project Steering Committee to assess water demand in Wangaratta and consider alternative water options to improve water security in the region.
Goulburn-Murray Water is a technical advisor to the Project Steering Committee.
Phase One of the Water Security for Wangaratta project, which assessed the region's current and future water needs, is complete and the consultants' technical reports are available online.
Phase One identified increasing use of groundwater, expanding Lake Buffalo or using alternative water sources as options to meet the shortfall in the town's future water supply requirements.
Phase Two of the project, which started in April 2014, will investigate the feasibility, including costing estimates, of these three options.

Lake Buffalo is located on the Buffalo River, 24 km south of Myrtleford in north-eastern Victoria. It lies at the foot of the western slope of Mount Buffalo National Park, and is a popular fishing, water skiing and picnicking venue.
Lake Buffalo was originally planned as a two-stage project. Stage 1 involved the construction of a 31 metre high and 600 metre long earth and rockfill embankment, with a gated primary spillway and outlet works located within the dam wall. This structure was completed in 1965, and created a storage with a capacity of almost 24,000 ML.
The water stored in Lake Buffalo is used to supplement flows in the Ovens River for irrigation and urban water supply. The dam initially supplied a thriving tobacco industry in the valley, however this has now changed to numerous vineyards.
The capacity of the storage represents only 6% of the mean annual flow in the Buffalo River.
