Groundwater lowering a<br />
threat to Lakes Eliza and<br />
Robe: lowering freshwater<br />
pressure and increasing<br />
saline water pressure.<br />
Changes are unlikely to<br />
affect swell wave climate,<br />
apart from increase in mean<br />
wave period.<br />
(Changes in upwelling timing<br />
and frequency has been<br />
discussed, but not<br />
projected).<br />
Monitor seasonal water<br />
levels and salinity in<br />
both lakes. Adaptive<br />
management of<br />
ecological assets.<br />
Lakes represent an<br />
obvious change in<br />
regional<br />
groundwater<br />
change. Lowering of<br />
regional water table<br />
(and perched water<br />
tables in dunes) a<br />
threat to all habitats.<br />
