Matt Chotlos is an undergraduate student at UW-Madison. For the last two summers, he’s been waking up at UW-Madison’s Trout Lake Station in Boulder Junction five days a week with a group of other researchers and driving to McDermott Lake in Iron County, where he traps bass and other sunfish–up to 2,000 a day–with the goal of removing every last one. By the end of this July, he had helped remove a total of 150,000 fish.
