the bulk of the assets are in the highlands west of the midlands - the midlands is a dustbowl - or was - there is major irrigation schemes through there only recently.
we would often see duststorms there as one drives from Lonnie to Hobart.
Most certainly all the catchment assets are in the highlands with the odd one being outside of that - like near Wilmot and in the South - but, you can't have something like that in the midlands - it's flat as a fart and dry as a chip.
