Lead is the shot used for skeet shooting, not steel. Lead levels are definitely detectable in water. There is a private skeet range a few miles from my house where they do all of the shooting towards a large pond for safety reasons. There are fish in it but they are NOT good to eat at all. The water definitely tests positive for lead. Lead shot is banned for waterfowl hunting becasue ducks and geese ingest the lead shot off the bottom while feeding. All around it is bad to shoot them near the pond.
