I don't know much more than what I could find on the net. I know its quite normal.

"*values far in excess of 100% saturation are possible, even common

*on bright summer days photosynthesis produces oxygen faster than it can diffuse to the surface and escape

"Sunny days with lots of photosynthesis or turbulent water conditions can lead to supersaturation."

"During daylight hours, it is not uncommon to find oxygen values in surface waters that exceed those listed in Table 5 (supersaturation), while at night or early morning before photosynthesis begins they may fall below those values."

Christy, no I don't have them in ppm. There's a switch on my meter I could toggle to get ppm readings for future tests.
