On Wednesday, July 1, the waterway reached minor flood levels, peaking at 4.97m about 1.15am.
The river reached its highest level, above the moderate flood level of 5.2m, at 6.15am on Friday, July 3.
Due to weather conditions including increased rainfall and winds, the SES Seymour Unit attended about 30 incidents, with nearly 20 being attended overnight on Wednesday and into Thursday morning.
“There seemed to be a significant wind event that happened at about 9.50pm on Wednesday evening,” unit controller Christine Welsh said.
“It came through and trees were just ripped out and broken off.”
While many of the jobs were flood watch related, such as monitoring local road closures, the unit did attend two water rescues outside of Seymour.
In Euroa, the individuals involved were “walked out” from the scene. However, in Lancefield, Ms Welsh said a person was air winched and taken to hospital with hypothermia.
Ms Welsh said, during harsher weather conditions, there were a number of things people could do to prioritise their safety.
“For me, the VicEmergency app is super important. Download it — you get the advice, you get the warnings, you know what’s going on,” she said.
“Secondly, especially for our area, you can jump on Google or the Mitchell Shire website and download our flood emergency plan.
“Thirdly, monitor the river levels, especially for the lower lot areas. Monitor them yourself and make that decision early to get out.”
She added that trees over roads, such as an incident attended by the local unit at Emily St, Seymour, on Wednesday, were a dangerous result of these conditions.
She said if people saw trees over roads, they should alert emergency services as soon as possible.
From Friday, the Goulburn River at Seymour started dropping and, as of Tuesday morning, was measured at 1.94m.
Minor flooding also occurred across the region throughout last week, including along the Yea River, King Parrot Creek, Sunday Creek and Hughes Creek.
