There can be lengthy delays for satellite imagery. As of March 2010, Google maps satellite imagery is from pre-drought conditions at least pre 2006. The links below are aerial photos from the website Nearmap.com with imagery of the Lower Lakes from 29 December 2009. The expanse of dry lakebed is clearly visible in these aerial photos as well as some of the critical acid hot spots.
