Finniss River at Winery RoadIntroduction

The Finniss River is one of the main rivers on the Fleurieu Peninsula. A fresh to brackish stream, it flows from the eastern side of Willunga Hill into Lake Alexandrina near Clayton. This site on Winery Road is one of two sites being monitored on Finniss River (see also Finniss River near Yundi) and is on the lower reaches of the river. Land uses in the catchment include dairy farming, forestry, horticulture and grazing. Elevated turbidity and nutrient levels are the most likely water quality problems. The site is surrounded by reed beds with grasses and eucalypts on the banks. >> Map (1.7MB PDF)

Water quality assessment

Water quality is assessed as being in good, moderate or poor condition by interpreting water chemistry data in the context of protecting environmental values. Water chemistry is measured each month. >> More

Water chemistry

The indicators that are measured in the Finniss River at Winery Road are nutrients (nitrogen and phosphorus), turbidity and salinity. The concentrations of these indicators are used to classify the water chemistry as being in good, moderate or poor condition, according to the needs of aquatic ecosystem protection.

The nutrient and turbidity levels were low in the Finniss River at Winery Road during this period. Nutrient concentrations are often elevated at this site during winter months, coinciding with rainfall and higher stream flows. The low concentrations in this period were possibly a consequence of the unusually low flows that occurred.

Concentrations are also generally less than at the site near Yundi, which is higher up in the Finniss catchment. This is possibly because agricultural landuse is more intensive in the upper reaches of the catchment and the river processes naturally reduce nitrogen pollution.

What is being done to improve the condition of South Australian rivers and streams

Efforts to improve the condition of South Australia's rivers and streams are being driven by various government agencies, primarily:

The Environment Protection Authority
The Department of Water, Land and Biodiversity Conservation
Natural Resource Management Boards
Department for Environment and Heritage (SA)

Collaborative projects and programs being run by these agencies are based on the protection of environmental values, as explained in the National Water Quality Management Strategy. >> More
