Namoi Valley - Flood Report Jan-Feb 1984

"Damaging floods are not uncommon in the Namoi Valley, with early reports of flooding dating back to 1865. The most recent flood causing widespread damage throughout the valley occurred in January - February, 1984.

The floods occurring in the Namoi River are similar in behaviour to floods of the other major inland streams flowing to the West.

In the upper reaches the catchment concentrates the floodwaters which move swiftly, but because there are no extensive flood plains the damage is localised. Bridges, culverts and roads are worst affected, there being only limited damage sustained by farming development, while stock losses are few. However, in the middle and lower reaches the carrying capacity of the river channel decreases and floodwaters are spread over a vast flood plain through a system of effluent streams. Here roads, railway lines and vast areas of farming and grazing country have been inundated with resulting high stock losses, crop losses, economic loss and personal hardship.

This report outlines the general features of flooding in the Namoi Valley and describes the meteorological and hydrological features of the January - February 1984 flood in particular."
