One of the dams, above us on the Columbia River, has developed a 65 foot crack. They've had to fiddle with the flow on some other dams to relieve the pressure and attempt to fix it. A whole bunch of area, that used to be underwater, is now shoreline. Those are freshwater mussels littering the area.
They also found.... a pile of human bones. At first inspection they seem to be very, very old. A friend for Kennewick Man perhaps?
PS - The Engineer worked at this dam and says even if it completely goes it will be fine downstream.
