>Dam failure
The Edenville Dam that collapsed had some kind of dispute and had lost its hydro license this year. They needed to make a better emergency plan (irony).
There's also some kind of ongoing property dispute around the lake and dam. It's privately owned but regulated by FERC. Their website has dam info and legal proceedings that were going on back in December/January/February.
Just a quick look so far but maybe someone else wants to take a look.
