Big waters, big fun, big dollars
Minnesota's 10 largest inland lakes are sparkling jewels in the state's fisheries and tourism crowns. With a combined surface area of more than 825,000 acres, these lakes account for about 40 percent of the annual statewide walleye harvest and make a significant contribution to the $2.4 billion spent each year on fishing in Minnesota.
Each lake is part of the DNR's large lake monitoring program and has its own fisheries biologist based in a nearby area office. Each biologist oversees an intensive fisheries management program that includes annual fish population assessments, annual water quality monitoring, fish contaminant and disease inspections, zooplankton surveys, aquatic invasive species surveillance and regularly scheduled creel surveys.
