  1. Values, except elevation and surface area, are means of the four sampling periods (June 2007, August 2007, June 2008, and August 2008; Rabbit Lake was not sampled in June 2008 and Middle Lake was not sampled August 2008). Lakes are sorted by increasing salinity. P and M represent polymixis and meromixis, respectively.
