Water will be released from Lake Boga in the coming weeks to meet Murray River customer demand.
Goulburn-Murray Water (GMW) River Operations Manager Andrew Shields said Lake Boga was one of the Victorian mid-Murray storages.
“Lake Boga’s operational purpose is to harvest and release water for distribution to Murray River customers,” Mr Shields said.
“Water is now required from Lake Boga to meet demands downstream of the Little Murray Weir.”
GMW plans to return water to the Murray River from 18 January. The storage is currently about 87 per cent full and is expected reduce to about 55 per cent by early March.
Recreational users are reminded to be to be cautious of hazards in the lake as the water level falls. These could include submerged or exposed rocks, sandbars, trees, shallow water and debris.
Lake Boga diverters may need to extend suction lines.
GMW plans to refill the lake from River Murray flows later in the year depending on conditions during winter and spring.
Lake Boga is the most northerly of the Kerang Lakes and lies approximately 16 km south east of Swan Hill and 40 km north of Kerang. Lake Boga is on the north eastern edge of Victoria’s Mallee Region.
Until the mid 1960’s Lake Boga was part of the Torrumbarry Irrigation System, and then it came to rely on floodwaters from the Avoca River and surplus flows from the River Murray when available.
Lake Boga now forms part of the Victorian Mid-Murray Storages (VMMS). The VMMS includes Kow Swamp, Kangaroo Lake, Lake Charm and Lake Boga, with a combined active capacity of nearly 58,000ML.
The Lake Boga Coordination Group, (LBCG) a government agency group was formed and is responsible for the coordination and communication of key transition programs.
The LBCG released the Lake Boga Land and On-Water Management Plan in November, 2011.
Lake Boga has a fascinating history and began with its naming when Major Mitchell passed through the area; it also has a rich indigenous past and strong connections with the Moravian Mission. During World War II it became the largest inland flying boat repair base with anything up to 1,000 air force personnel based at Lake Boga.
Several books have been written about the area and two that have provided a great deal of valuable information are “Tresco Estate”, researched and written by John Jobson, 2007 and “Between the Rivers”, researched and written by Grant Angus with Colin Heggen and John Jobson, 2009.
The VMMS operational objective is to; capture, store and release water for the benefit of the Victorian Murray System users. Water will be harvested into the Victorian Mid-Murray Storages and then returned to the River Murray to supplement down stream bulk water demands.
Individual storages will now experience greater season fluctuations in water levels than in the past, but under the current operating regime the probability of Lake Boga drying up as it did in 2000 for a prolonged period is unlikely. Storage operating levels will be higher in the early months of the irrigation season, particularly October and November.
Goulburn-Murray Water will undertake VMMS operational manager function and will implement the VMMS ‘capture’, ‘store’ and ‘release’ objectives for the benefit of the Victorian Murray System users.
Land and On-Water Management Plan
The Lake Boga Land and On-Water Management Plan provides a strategic approach to management of land and on-water issues at Lake Boga and was completed in November 2011. The Plan was developed in consultation with community, lake users, local government and other agencies.
The Plan aims to identify and protect important values associated with the lake by outlining priority land and on-water management issues and identifying key issues to be implemented to address these issues. Most importantly, the Plan aims to increase communication, consistency, co-ordination and co-operation between agencies, stakeholder groups and the community to enhance the lake’s values and attributes. The Plan does not make recommendations on storage operational issues, including storage filling and releases, as those decisions are beyond the scope of this plan.
