THE Murray-Darling Basin Authority (MDBA) is trialling a different method of water releases from Hume Dam using the spillway gates in a bid to improve downstream water quality.
MDBA acting executive director river management Dr Andrew Kremor said dissolved oxygen levels remained low immediately downstream of the dam for several kilometres​, even though the MDBA had been releasing water through the valves to increase aeration, and compressed air has been added to water releases through the power station since earlier this month.​
