Two big sections of pvc pipe glued up and a manure fork bent so you can lift straight up. I bet you can find it and rake it right back up.. Maybe anyway! I hope the bottom is sand or stone and not muck.!
Unless it's a piece of crap a couple days in the water ain't gonna kill it. Might take a little muscle work but it will clean right up. Drop it in the salt water behind my house however and you will be able to watch it rust.
Be careful out there!! Waters getting awful cold to be spending to much time in it!
