Bob hit on all the topics also dirt was not compacted in layers also was dirt partially frozen or water logged clay and humus used for damm.Exessive slope on outer bank best thing to do is drain pond and fix in spring if seal key was not properly installed at base of damm this could also be a problem. With the cold weather we have now useless to try to repair. Suggest you maybe get another opinion from local dirt man and compare notes when your man comes back from florida.
