LATE last year several of my friends sent off postcards as part of the Australian Environment Foundation’s Rivers Need Estuaries Campaign. You can still send a postcard and sign the petition here:
There is a choice of message, for example:
Dear Senator,
Maintaining artificial freshwater lakes using 7.6 kilometres of concrete barrages has:
1. Destroyed the Coorong-Murray River estuary;
2. Diverted water from upstream environments and communities to keep these artificial lakes supplied;
3. Not improved the water security of Adelaide.
I ask you to support moves to:
1. Remove the barrages from the Lower Lakes to restore the Coorong-Murray River estuary; and
2. Relocate Adelaide’s water take-off to a proposed lock downstream from Tailem Bend.
Signed K. Smith

Just today there has been a flurry of responses from Simon Birmingham Shadow Parliamentary Secretary for the Murray-Darling Basin to postcards sent last December. The Senator is mostly replying with a form letter as follows:
Dear Ms Smith
Thank you for your email regarding the Lower Lakes.
