Lake Superior (known as Gichigami, or ‘big lake’ in Ojibwe) is the largest freshwater lake in the world by surface area and the third largest by volume, holding 10% of the world's surface fresh water. The lake straddles 150 miles of Minnesota’s northeastern border, with its most western edge ending along the city twin ports of Duluth, Minnesota and Superior, Wisconsin.
September 21, 2017 - Morning Edition’s Cathy Wurzer interviews April McCormick, a member of the Grand Portage Band, who worked closely with the Nature Conservancy on bringing Susie Island back under the band’s control.
October 31, 2017 - MPR’s Dan Kraker looks into the ongoing battle to control sea lamprey in the Great Lakes. It was one of the earliest aquatic nonnative species to invade the U.S., long before zebra mussels and Asian carp garnered headlines. Its also been one of the most destructive, wiping out lake trout populations.
August 14, 2018 - MPR’s Dan Kraker reports on unprecedented algae bloom along the South Shore of Lake Superior. Researchers are trying to figure out the cause. They suspect the bloom may be related to recent historic heavy rains and flooding that washed tons of sediment into the lake. Researchers expect to see more periodic algae blooms in Lake Superior, in part because of that increased water temperature, an effect of climate change.

March 8, 2019 - MPR’s Dan Kraker visits an area about a quarter-mile offshore from Duluth's Leif Erikson Park, where a hearty band of volunteers have carved a skating rink unlike any other on the frozen surface of Lake Superior. It is an increasing rarity, as warmer winters over the past few decades have resulted in substantially less ice cover.
March 27, 2019 - Springtime in Duluth isn't signaled by birds or butterflies or flowers. Duluthians know it's spring when the Coast Guard icebreakers arrive, announcing the start of another Great Lakes shipping season. MPR’s Dan Kraker takes a ride on the U.S. Coast Guard cutter Alder as it breaks ice and creates navigation lanes for the opening of the maritime shipping season.
February 25, 2022 - MPR’s Dan Kraker reports on Lake Superior research known as the “Winter Grab.” Scientists have a pretty good understanding of what goes on in the Great Lakes during the summer. But they don't know nearly as much about Lake Superior and the other lakes during winter. That's significant because winter is when the lakes are experiencing their most dramatic impacts from climate change.
November 10, 2022 - As a powerful storm hits Duluth on the anniversary of the Edmund Fitzgerald tragedy, MPR’s Dan Kraker looks at what makes the gales of November on Lake Superior so memorable.
