36 Buffalo Creek 2014 5.8 Buffalo Creek The area is characterized by long residence time and poor flushing due to the sand bar at the creeks mouth. Buffalo Creek receives discharge from the Leanyer-Sanderson Wastewater Treatment Plant, and pollutant loads from urban areas during the wet season. Figure 16 summarises the results of water quality parameters measured at the Buffalo Creek monitoring sites. This data is collected by the Power Water Corporation. Table 12 reports median values and 20th-80th percentiles (compliance), minimum and maximum values of the data measured in Buffalo Creek. Table 12 - Summary of water quality parameters measured in Buffalo Creek Three water quality parameters measured (water clarity, algae and nutrients) did not comply with the WQOs: Water quality at the Buffalo Creek reporting zone is in poor condition. The highest values of chlorophyll a, ammonia, total nitrogen, total phosphorus and filterable reactive phosphorus were measured at sites closest to the Buffalo Creek outfall.
