Popularity of winter angling placing unprecedented pressure on some of Minnesota's most productive walleye lakes

At 11 p.m. on a recent Saturday, Lindy Frasl put the finishing touches on the third ice-fishing wheelhouse he has built. At 20 feet, this one was bigger than the other two, but similarly outfitted, with four bunks, a TV, bathroom and small kitchen.

Five hours later, Frasl, of Brainerd, was en route to Upper Red Lake to fish for walleyes, joining there a few thousand other ice anglers.

"Upper Red is unique because it's a big basin and there's no underwater structure in any one location that holds fish," Frasl said. "I don't stay in one spot longer than a day. I move to find fish."
