Mr Rann has put this weir at wellington idea forward as a stratergy for drought. When there is no rainfall they pump water from Mannum to the river torrens at birdwood which then fills up the adelaide dams. If they have low flow in the murray they cant do this and therefore need to put a weir at wellington. I believe that this will effect both the water levels and quality at boggy lake. On the flip side it may also create a fanastic speed venue with less chop

Bubs, the race on sunday will probably be a giant slalom (Big figure 8).
