Q: I am on a three acre lake in Roswell. A developer put in a road on the other side of the lake and in so doing, he in filled along about 400 feet of the shoreline. Fill is red clay and is to a depth of 8 to 10 feet. This was done two years ago.
A number of the home owners on the lake use the water for irrigation. Since the fill was put along the bank, the water has been staining our patios, houses and plants (actually kills the lamb’s ear and some flowers).
I am guessing that the stain is coming from the fill – maybe iron in the red clay? I have heard that we might be able to treat the lake to precipitate the staining agent.
A: I’m not an expert on this but members of the Georgia Lakes Society:

The Georgia DNR keeps a list as well: Pond Management Information
Aquatic Environmental Services manages many lakes.
