The salmon eating Puget Sound orcas are doomed because they are too many for the available food supply.  

So in 2015,  with tens of millions invested in refrigerated river water barges,  NOAA and Corps of Engineers dragged their feet on a decision to haul chinook smolts to colder tidal water in the Lower Columbia because,  after all,  they really need to go to sea with a flush of river water.  Yep.  Only it don't work when the water suddenly is over 70degrees F,  and the fish mostly died.  Only 13% of the potential smolts were barged.  The rest cooked.   Oh,  and so that is now bandied about as a good reason to remove the only dams on the entirety of the Snake River with fish ladders.  And in a warming world,  with those dams you lose the locks and the ability to barge the smolts in cold water to where the water is survivable.   The orcas are doomed,  collateral damage in a turf fight inside our Government.
