The Mandagery Creek reached 6.4 metres at the bridge in Eugowra on Tuesday afternoon following the weekend's rains.
Greg Agustin, who was monitoring the water level, said it peaked on Tuesday afternoon and was going down slowly on Wednesday morning.
Reports from Eugowra and surrounds are that people recorded 73 to 80mm of rain, about three inches, across the three days.
Although the creek rose to its highest since 2016, to Mr Agustin's knowledge there hadn't been any impact on local roads.
"We were lucky the rain was over a fair period, it wasn't really heavy," he said.
A flood warning was issued for the Belubula and Cabonne Council advised on social media a number of roads around Canowindra and in other parts of the shire were closed due to flooding.
Those included: Belubula Way, Finns Lane, Canowindra to the Swinging Bridge, Mackeys Creek Road, George Russell Drive and Settlement Bridge. Council was updating advice via Facebook.
