Here was my part of the find from a couple hours at Kiwanis Lake in York PA. All told we found 3 knives, a bucket of campaign style buttons, a mess of fish hooks, a rod holder, a fork, large metal stake, a lawn chair, various bits of metal, and my big find was a Razor Scooter, in working condition.

If anybody asks questions, I would just say that you are trying to retrieve a boat anchor that you lost.
Now you just need to find a magnet that can pick up non-ferrous metals
