A Tale of Two Seasons


After the wet year of 2005, by 2008, water availability fell drastically in South Australia's Eastern Mount Lofty Ranges. The above photo-pair shows the same farm dam in those two respective years. The aquatic abundance of 2005 gave way to unprecedented aridity in 2008.
On a more serious scale, 30 km to the east, the Murray River at Mannum, illustrated by the background for the MOPS heading, reveals the extensive dry flats which have replaced the wide lagoons regarded as characteristic of this, the lowest of the river's pools. In mid-2008, the Murray River level at Mannum had sunk to 1.5 metre below "normal". Until the river receives more flow below Lock No.1, the outlook for Adelaide's supplementary water supply derived by pumping just downstream of Mannum is truly grim.
