The Tabourie Lake Broadwater is fed primarily by Lucy Kings Creek and Munno Creek. These tributaries are the primary source for the Tabourie Creek. The major tributary of Branderee Creek merges with Tabourie Creek and almost doubles the contributing catchment area from 21 to 40 square kilometres. Lemon Tree Creek (or Saltwater Creek) completes the major creek contributions entering upstream of the Tabourie Creek outlet to the Tasman Sea.

The overall objective of this study is to develop a Floodplain Risk Management Plan to present the proposals resulting from the Floodplain Risk Management Study. The plan describes how the land in the study area is to be used and managed to meet the defined objectives of the Floodplain Risk Management Study. The FRMS investigated what could be done to reduce or manage the effects of flooding in the catchment and recommended a mix of strategies to manage the risks of flooding.
