About Buffalo Creek

Buffalo Creek is a small tidal creek in the Shoal Bay receives discharge from the Leanyer-Sanderson wastewater treatment plant.

The creek is poorly flushed and discharge is not readily dispersed, causing a build-up of nutrients and excessive algal growth.

A small area of the newly established suburb of Muirhead also drains towards Buffalo Creek delivering urban stormwater during the wet season.
