I would wait until september before worrying about salmon in the rivers. mid August pier fishing will start, september the runs will start. its not going to be a full month ahead of schedule, usually differs by a week or so.
Anyways, Ill be carping untill october when the real chromers fire up. boots, silver or black still arent all that great of a fish to catch unless your downrigging on a boat in the summer. Ill just wait til october and grab up on some already dead carcasses to fertilze my garden, other than that, Ill leave the chinnies to the loogans. my 2 cents
