I tried valiantly for an hour to get a photo uploaded, but I haven't been successful. I'm a new member, and perhaps I missed a step somewhere, but more than likely it's my miserable internet connection in this rural stretch. I will try again, and label it as floating clay.
I talked with the people at ProSkim about their neat unit for skimming surface weeds off a lake, thinking it would be a great solution for me. But they said that what I described sounded like electrostatically charged clay, topped with grass clippings and an occasional topping of green spikes that rooted into the floating clumps soil. They said floating clay was often seen in the southeastern portion of the country.
The only submerged weed we see in this lake is slender spikerush along some shorelines, and I'm told that slender spikerush is just about impossible to kill. I can see that same type of soil-like topping on the spikerush under the water--it looks like the same stuff that is floating on top of the lake. When I do get a photo up, you will think it looks like algae, which it looks like from a distance. I tried Cutrine plus, copper sulphate, etc. early in the year trying to keep this stuff from proliferating, but no go. I thought maybe it was brown algae.
We do spray with Accord along shorelines for aquatic primrose, but Accord and algae control are the only chemicals I have put in this lake. Our 7 acre lake on the top side of the dam looks great--none of this stuff. This lake is newer, built 5 years ago.
Thanks for the response DD2 and I'll try to upload a photo again.
