Jackson Creek (Victoria)

Formed by the confluence of the Distill, Gisborne and Slaty creeks that drain the southern parts of the Macedon Ranges, part of the Great Dividing Range through the Black Forest, the Jackson Creek rises northwest of Gisborne, within the Rosslynne Reservoir.

The creek flows east, then south, then south by east, joined by two minor tributaries before reaching its confluence with the Deep Creek to form the Maribyrnong River west of Melbourne Airport.

The deep and relatively narrow valley cut by the creek in its southward course through the surrounding basalt plains is particularly prominent at such places as Emu Bottom and the Organ Pipes National Park.

[3] The incised meanders of the Jackson Creek demonstrate the downcutting of the Newer Volcanics and have formed rapids and small falls, along with outcrops of columnar basalts and tessellated pavements, for example at the Organ Pipes National Park near the Calder Freeway, a prominent display of basaltic columns so named because they look like organ pipes.

Upstream, a bluestone flour mill near the falls south of Sunbury harnessed the major drop in river levels.
