thanks for the input

do you think it actually turned over twice?
Nope, not likely at all because to turn over twice it would have to restratify. Not going to happen. Two things to keep in mind though. One is that the whole process usually takes weeks to complete. It's not a show up to the lake one day it it turned over overnight. That said, once a section has completed turnover it is very susceptable to full mixing with heavy winds.

The other thought that hasn't been mentioned is related to algae/plankton, or related blooms. As water temps change, certain planktons and algaes die off (clearing water) but others get fired up (stained water). This is referred to as algal succession. That brown particulate colored water you're seeing is very common around here (Indiana) this time of year and is usually attributable to a diatom bloom. These blooms can come and go as water temps cycle through rising and falling temps due to local weather patterns. My guess is that that is what is occuring on your lake.
