Spot, I don't consider myself an aquatic expert, but I've been testing the waters of Lake Martin on a monthly basis for nearly 25 years under the Alabama Water Watch program at Auburn University.

I'm wondering where you got your information about Dissolved Oxygen in the lake.  Are you talking about Dissolved Oxygen or Dissolved Oxygen saturation?    Big difference.

In well over 200 tests off my floating dock in the upper portion of the lake, DO has never been below 5.5 ppm (that's good). DO saturation has ranged from 65 percent to supersaturation above 100 percent (also good).  This has a lot to do with temperature and nutrient enrichment.

My results are very consistent with many years of data from other Lake Watch volunteers who have tested hundreds of times on dozens of sites on the lake during the same timeframe.

Interesting question and I appreciate your interest.  Hope this helps.
