Unless there was some sort of very strong current, it's very hard for a floating disc to climb back onto land. So if one side was on land, it's pretty safe to say that it came to rest there. You can then mark one-meter in from the OB line (shore) and throw from there. Assuming the lake itself is actually OB, you cannot wade in and throw from there, all of your supporting points must be in bounds.
