The North Para River rises from the Barossa Ranges near Eden Valley and flows southwest through the Barossa Valley, passing through the towns of Nuriootpa, Tanunda, before merging with the South Para River in Gawler forming the Gawler River.
The North Para River catchment is one of the key watersheds in the northern Mount Lofty Ranges. It plays a very important role in the economy of South Australia, providing much of the water used by viticulture in the Barossa Valley. Its waters are also used for livestock production, cereal cropping and recreation.
