Lake Bellfield

Last year

Lake Bellfield is located in the eastern Grampians near Halls Gap and has an inlet from Fyans Creek. Lake Bellfield supplies water to Halls Gap and Pomonal. It's also the main source of supply for the Wimmera Mallee Pipeline system, supported by Taylors Lake. The lake is used for recreational activities such as boating, fishing and picnicking.

Natural disasters in past years, such as the Mt Lubra fires in 2006 and the floods of January 2011 have badly affected the water quality of Lake Bellfield. We have recorded record levels of turbidity and water colour in recent times.
