Mid North of South Australia
The Mid North Region
The Mid North (77.3 KB PDF) is a region of South Australia, north of the Adelaide Plains, but not including the Far North, or outback. It is generally accepted to extend from Spencer Gulf east to the Barrier Highway, including the coastal plain, the southern part of the Flinders Ranges, and the northern part of the Mount Lofty Ranges. Agriculture, viticulture and sheep farming are significant industries in the area.
The Mid North possesses significant wind resources and several wind farms have been built in the region. Wind farms constructed in the region are situated on top of high ridges, providing good opportunities for electricity generation, even when wind speeds in the surrounding valleys are not high.
Although the terrain is varied, it is particularly rugged only in the Southern Flinders Ranges. On the west is a coastal plain, narrowing north of Port Pirie. East of the plain a series of ridges of sandstones and quartzite run roughly north and south. Between them, on less resistant shales and slates, are wide valleys and flats. There is an intricate pattern of streams, but most flow only after heavy rain.
Annual rainfall varies between 350 mm and 500 mm, with falls up to 650 mm in a few areas in the Clare hills and South Flinders Ranges. Average monthly rainfalls and variations in the mean temperature are represented in Figure 1.
