Thanks guys I'll try and post some before and after pics. I'm heart broken. A lot of time and money was gone in a flash. The funny thing is when we built it we hired a professional pond building company to build it. The guy who built went on and on about how he's never lost a dam. Never say never I guess.
Give him a call and ask him if he'd like to put the permanent dam in this time around.
Looks like more weather is coming. Stay safe!
