Storage, River Flow and Rainfall Update

Monday, July 29th, 2019

Rainfall recorded at South Gippsland Water’s storages during the week of 20 – 26th July 2019 was Lance Creek 27mm, Ruby Creek 17mm, Deep Creek 16mm and Battery Creek 15mm.

South Gippsland Water’s Managing Director, Philippe du Plessis said, “All reservoirs reaped the benefit of heavy rainfall over the past weeks with storages at levels we would expect for this time of year.”

Lance Creek (Wonthaggi, Inverloch, Cape Paterson, Korumburra, Poowong, Loch and Nyora), Battery Creek (Fish Creek) and Deep Creek (Foster) reservoirs are at 100% capacity, followed by Ruby Creek reservoir (Leongatha, Leongatha South and Koonwarra) at 79%.

“The Ruby Creek system is making good progress and we’re encouraged that, with additional rainfall throughout the second half of winter, the reservoir will reach capacity in preparation for the demands of summer,” Mr du Plessis.

Catchments are now well saturated and the percentage of runoff into reservoirs has increased.

“This can be a mixed blessing; increased inflow improves storage levels but can add sediment and debris to raw water,” explained Mr du Plessis. “The raw water in each supply system is monitored and treated in-line with normal business operations to ensure it meets Department of Health regulations.”

Water quality and operations staff regularly monitor and test all South Gippsland Water supplies as part of routine operations and treatment and processing is adapted to meet any change in conditions within each catchment.
