Thank you all for your excellent input. Fortunately, the phenomenon has subsided substantially. There is hardly anything on the water this morning. The lake looks fantastic. One of our neighbors is a Biology professor at one of our local universities. He took some water samples yesterday. I will let you know if he finds anything interesting. The good thing is that the "foam" is on the decline. Hopefully this trend continues. On another note, I didn't come to this forum to make enemies. If I did so, I apologize. Thanks again for your help. I hope to use this forum for years to come.
