First time I've ever heard of lightning striking a pond but I'm sure it happens.
Flags, more than likely the pond started out deeper than 3 ft and has silted. If so, removing the gunk is tough. It's about like scooping up pudding and you have to find a place to put the stuff that is excavated. It might be less expensive to build another pond or to walk away and find another place.
Ask the guy when the pond was built and the original depth.
Just noticed your name. My grandfathers guitar player's name was Dave Davidson. They won dang near every fiddling contest they went to if they didn't get too drunk to play. Dave was the best guitar player I ever saw. They won 7 world championships together. My grand dad was from Whitewright, Dave lived in Paris. Just thought I'd share that. Dave Davidson isn't a common name but I happened to know one that was a legend.
BTW, I have never seen or heard of any other pond getting hit by lightening like that. But that was the only explanation. We fished the pond earlier that day and no dead fish. After the storm almost every fish in the pond was belly up with their eyes bulging out.
If it ain't yours don't mess with it!
