House of Assembly Fifty-Second Parliament, First Session (52-1) 52 1 Parliament of South Australia House of Assembly published Answers to Questions Clayton Weir CLAYTON WEIR In reply to Mr WILLIAMS House of Assembly MacKillop Deputy Leader of the Opposition CLAYTON WEIR In reply to Mr WILLIAMS (MacKillop—Deputy Leader of the Opposition) (14 September 2010). The Hon. P. CAICA House of Assembly Colton Minister for Environment and Conservation Minister for the River Murray Minister for Water CLAYTON WEIR The Hon. P. CAICA (Colton—Minister for Environment and Conservation, Minister for the River Murray, Minister for Water): I am advised that: With the current predictions for inflows into the Lower Lakes, the trigger for the partial removal of the Goolwa Channel Regulator has been activated. The Government is currently undertaking partial removal of the regulator. The cost associated with the partial removal is approximately $110,000. Full removal of the regulator will be triggered when advice from the Murray Darling Basin Authority confirms that the water level in Lake Alexandrina will not fall below sea level for two consecutive water years, or the combined discharge from all barrages will exceed 15,000ML per day for more than 30 consecutive days. While the water level triggers for full removal have not yet been met, the options for removal and their costs are currently being assessed.
