East of the end of the Point Sturt Peninsula, South Eastern corner of Lake Alexandrina, South Australia.

Sample taken approximately 400m out from the land, this area is covered by 1.5m of water in normal times.

What's going on:

Lake Alexandrina is currently 0.8m below sea level, it is normally held at 0.75 above sea level by the barrages.

The current situation has been caused by over-extraction of water in all the MDB states and mismanagement of the system, both have been exacerbated by the current drought and not enough water allocated to retain the health of the River system.
