Wow Tyler those photos really tell the story. Sorry to see such damage to your pond. If it were me I would contact Mike Otto. Mike is one of the top pond builders in the US. I think it would be well worth it to have Mike take a look at your pond, spillway and dam.

You can find the contact info for Mike Otto and other pond builders in the Pond Boss Resource Guide... Pond Construction, Pipes and Other Pond Hardware.
