I was doing an appraisal inspection on a lake property in Shelby County, Alabama recently and ran across this unknown item. I don’t know what it is myself so I thought I would ask everyone what they think it is. I will tell you that they were doing some dredging and clean up of the lake so it could be related to this. Do you know what it is? Please let me know, I will be be eagerly awaiting your guesses.
