If there are diverse kinds of knowledge and ways of knowing place, then we need to learn to value the different ways each of us sees a single place that is significant, but differently so, for each perspective.

Murray-Darling Basin: drying « Previous | |Next »
June 22, 2009

Bit by bit the evidence indicates that the southern region of the Murray-Darling Basin is undergoing a significant drying event.

There is increasing evidence that a real shift in weather patterns has occurred over south-eastern Australia that is causing a generally warmer and dryer environment.This drying is expressed in less rainfall, less run-off, less river flows and now evidence of less water replenishing the groundwater systems.

With the consistent reduction in the amount of rainfall over the Murray-Darling Basin since 2001 we have seen reduced run-off from the catchment areas into the dams, reduced flows in the rivers and streams, drying out of the floodplains and wetlands and of course reduced amounts of water being used for irrigation.

What we don't see in this drying process is the reduced amount of water that slowly moves from the ground surface through the upper soil layers into the underlying aquifers feeding the groundwater system. In the absence of fresh water the dairy farmers around the lower lakes are tapping into the salty ground water.

Lake Albert is receding. That means a declining future for Meningie.

My quick impression of Meningie when we were there is that the canal development --Coorong Cove---at the southern end of the Lake is in trouble; businesses are struggling; the young are drifting away because there is no work; and property prices are falling big time.

A dry Lake Albert means that Meningie has no future as a holiday retreat. The only solution is sea water.
