Mike Osuch caught the heaviest walleye verified in modern Chicago off the southern tip of Northerly Island about 5:40 a.m. Thursday, Sept. 11.
He had it weighed at 7 pounds, 5.5-ounces on the certified scales at Henry's Sports, Bait & Marine Thursday morning.
The Stickney man was casting a deep-diving Reef Runner for salmon when he latched into the surprise of a 27 1/8-inch walleye with a girth of 14 3/4 inches.
That surpasses the 6.75-pound walleye caught by Toni Pellegrino in the Chicago River by DuSable harbor on Oct. 8, 2007.
The question remains, where did these walleye come from? Just visiting or setting up house?
