Downstream in Boggabri, the river peaked at 6.85m after 44mm of rain - one of the highest totals anywhere in the north west.
The Mooki River in Breeza and Gunnedah also overflowed its banks, and the Gap Road was closed near Werris Creek.
NSW SES Namoi Region Headquarters issued minor flood warnings for Tamworth and outlying areas.
For days, Gunnedah locals crowded the banks of the Namoi to take photos. One woman pointed to the half-submerged concrete pillars, which usually dot the edge of the car park, and said she had parked there one day and by the next morning, it was boat-only access.
The flooding was caused by a negative Indian Ocean Dipole (IOD) 5000km away.
A negative IOD means that as warm ocean temperature track toward Australia's west coast, rain clouds follow.
