I located these Ga codes by just hunting for hours on the web. I put in key words like "landowners rights, riparian rights, dam, water, etc". The exact code is listed in my post above.
This would be a great article for Pond Boss, but it would take a ton of work to reasearch. If I were writing the article, I would start with the Corps, as their rules theoretically affect everyone.
Now, I am wondering who has the final say...the State of Ga. or the Feds. I have always heard that state law superceeds fed in most cases.
