Not sure what exactly is going on... but I would be looking for ways that additional nutrients were leeching into the water... you are already looking at lawn fertilizer runoff... you might also consider whether aging septic tank systems in the area are adding to algae growth.   In othe lakes I have known (Guntersville being a prime example), there have been blooms of aquatic plants that foul the water.   I think the one on Guntersville was called Milfoil.   It's nasty stuff, smells to high heaven.  Not sure if that stuff has migrated to Lake Martin, but things like that have been known to happen.   It's like water-borne Kudzu.....

One of the good things about Lake Martin is that the annual rise & fall of the water inhibits this sort of thing... but may not eliminate it, I guess.

Good luck.  I don't like swimming in green water either.
