I was out trolling for springs on the weekend around Discovery Island in Haro Straight. Didn't catch any salmon, but holy crap was there ever a load of bait in the water. I was in about 130' of water and would come across HUGE bait balls that would have my sounder thinking I was in 30' of water!!! All sorts of them -- some big thick bait balls, and some scattered and spread out. They would be down between 30' and about 90' so I didn't see any of them but assumed they were Herring.
