Lower levels at Lake Mead have sent water managers scrambling to assess Southwestern water and energy needs.

But the falling reservoir is also revealing some surprises.

Earlier this month, boaters at Lake Mead discovered a barrel with human remains.

The victim has not been identified, but police said that the barrel has likely been at the bottom of the reservoir since the mid '70s or early '80s.

Police say he had been shot. A second body was found over the weekend, though the cause of death is unclear.

The finds have led to speculation that more bodies could turn up, and some could be victims of Vegas mob violence, though others could be drownings.
