This is a list of lakes of Minnesota. Although known as the "Land of 10,000 Lakes", Minnesota has 11,842 lakes of 10 acres (4.0 ha) or more. The 1968 state survey found 15,291 lake basins, of which 3,257 were dry. If all basins over 2.5 acres (1.0 ha) were counted, Minnesota would have 21,871 lakes. All but four of Minnesota's 87 counties contain at least one natural lake. Due to the abundance of lakes, many names have been repeated; for example, there are more than 200 Mud Lakes, 150 Long Lakes, and 120 Rice Lakes. Minnesota's lakes provide 44,926 miles of shoreline, more than the combined lake (~32,000 mi) and coastal (3,427 mi) shorelines of California.
