LAANECOORIE reservoir is at its highest July level on record.
Latest figures have the reservoir at 90 per cent capacity compared with 39.8 per cent a year ago.
Upstream, Tullaroop reservoir started spilling this week and Cairn Curran to just under 95 per cent.
The 7255 ML currently in Laanecoorie has historically been recorded in August and September, according to records that start in 1963.
Goulburn Murray Water says it will continue to pass all inflows into Laanecoorie.
Water storage services general manager Martina Cusack said on Tuesday: “Laanecoorie Reservoir is currently passing all inflows, ensuring the level of the storage remains stable.
“Approximately 800 ML per day is being released from Laanecoorie reservoir as of Monday,” she said.
“The storage is receiving about 350 ML per day from water that is being released from Cairn Curran reservoir, and a further 200 ML per day from water spilling at Tullaroop Reservoir.
“Flows from Cairn Curran reservoir and Tullaroop reservoir have risen following recent rainfall. 
“These flows are expected to continue and may change in response to inflows into the storages. GMW will continue to pass all inflows into Laanecoorie Reservoir.”
The Loddon River downstream of Laanecoorie on Monday was 1.21 metres compared with 0.45 metres a fortnight ago.
GMW says Laanecoorie Reservoir is a tilt gate storage. 
“This means that once the reservoir level reaches a certain height, the tilt gates open due to the weight of the water,” it said.
“Like a fixed crest spillway, flows downstream are governed by the water level in the reservoir.
“River flows in the Loddon system rise and fall very quickly in response to heavy rain.
”Laanecoorie reservoir has a capacity of 8000 ML. 
“This means it is relatively small in the scheme of the Loddon catchment. 
“For example, during the October 2022 floods, inflows into Laanecoorie reservoir peaked at about 144,000 ML per day, which is 18 times the capacity of Laanecoorie Reservoir. 
“Even in events like this, Laanecoorie reservoir does help lessen peak flows downstream.”
Meanwhile, GMW on Monday started releasing 800 ML a day from Lake Eppalock, with Ms Cusack saying the decision was  based on projected inflows.
