Muskie hunters cherish June. Striper fishermen adore October. But for the legions of anglers that chase chinook salmon in and around the Great Lakes, there is only September. This month, as giant kings move into rivers to spawn, they're at their most aggressive, and although the majority have lost their urge to feed, nothing ticks them off more than a plug, spoon, spawn sack, or fly dancing in their face while they're trying to get busy. You can wet a line with the crowd and maybe luck into a monster. Or you can seek the same conditions that these diehard salmon guides do. You can tie on their favorite lures, flies, and baits; use their presentation tricks and tips for winning the fight; and have your top shot at a personal-best chinook.
