Trundle is a rural community situated 60km north-west of Parkes in New South Wales. Trundle township experiences frequent flooding from Yarrabandai and Goobang Creeks and residents are isolated during floods for up to one week and access to Trundle Hospital is lost for several days. Parkes Shire Council (hereafter Council) is responsible for floodplain management in the town of Trundle.

The objective of this Flood Study is to define the flood behaviour of both Yarrabandai and Goobang Creeks on the urban area of Trundle. The study produces information on flood levels, velocities and flows for a full range of flood events under existing catchment conditions. These results will enable Council to progress to the next phases in the floodplain risk management process, by identifying the possible management options within the Floodplain Risk Management Study and development of a draft Risk Management Plan (the Plan).
