I haven't done anything scientific or technically advanced, but it's got to be at least a foot at the head of the pond near shore as determined by trying to walk on it and sinking in. The pond was built in '73 and although it's not silted in real bad, there's almost 40 years of stuff in there that I think I can make a dent in myself over time. I'm just trying to figure out what I want to do and what I'll be allowed to do under the heading of ongoing maintenance. The county wants a quick in and out approach.
