Sea lions occasionaly go through the locks at Bonn, but rare.
within that 30% of missing fish, you have to factor in the fish removed from the run related to recreational fishing, tribal fishing, "natural" mortality and the fact that spring chinook have one of the highest straying rates in anadromouse fish ie they end up in the wrong river system. So in reality the difference is about right.
