With a flood watch issued for the Northern Rivers, livestock producers are urged to move animals and infrastructure to higher ground.

NSW Department of Primary Industries and Local Land Services say the Bureau of Meteorology is predicting flooding across this area in coming days, so take care of your pumps and farm machinery too.

A spokesperson said heavy rainfall is forecast from today into Tuesday and Wednesday and catchments are already saturated following significant flooding in recent weeks.

"This rainfall has the potential to result in moderate to major flooding along the Richmond, Wilsons, Orara and Bellinger Rivers from Tuesday and minor to moderate flooding for other coastal catchments," the spokesperson said.

"We are encouraging all producers in these areas to make sure they have current flood plans in place.

To help producers prepare for flooding, they can download the Local Land Services’ Farm Flood Readiness kit at www.lls.nsw.gov.au/floods.

Flood-affected landholders should continue requesting assistance through the Agricultural and Animal Services Hotline by calling 1800 814 647 (operating 7 days, 8am to 8pm).

Landholders can request emergency fodder for livestock, animal assessment, veterinary advice and if required, euthanasia and burial via the hotline.
