Creeks and Rivers

The Tuggerah Lakes catchment spans 700 square kilometres and includes five major tributaries:

  • Wyong River
  • Ourimbah Creek
  • Wallarah/Spring Creek
  • Tumbi Creek
  • Saltwater Creek

Wyong River and Ourimbah Creek are the largest sub-catchment with Wyong Shire. Together they provide 72% of the freshwater inflow to Tuggerah Lakes. These tributaries flow into the eastern side of Tuggerah Lake and are an important part of the water supply network for the central coast.

Wallarah and Spring creeks merge at Blue Haven to become Wallarah/Spring Creek which flows to the eastern side of Budgewoi Lake. This creek system is the least developed of all the tributaries and is one of the most important habitat corridors in the Shire.

Tumbi Creek and Saltwater Creek flow into the southern section of Tuggerah Lake and are the most developed sub-catchments within the Shire.
