Just saying the water level should be more important with the Authorities right now, since it's critically close to closing down power generation.
As is usually the case: they're be reactive rather then proactive. Should be making plans for when/if that occurs.

Solve the water / looming power issue then worry about ID'ing the remains found. Hey maybe Hoffa will surface (no pun intended) but doubtful
