Lake Pepin is a naturally occurring lake on the Mississippi River on the border between the U.S. states of Minnesota and Wisconsin. It is located in a valley carved by the outflow of an enormous glacial lake at the end of the last Ice Age. The lake formed when the Mississippi, a successor to the glacial river, was partially dammed by a delta from a tributary stream and spread out across the ancient valley.
Lake Pepin is now a corridor for water, highway, and rail transportation. Known as the birthplace of water skiing, it hosts a variety of recreational activities.
The wide area of the lake stretches from Bay City, Wisconsin, in the north, down to Reads Landing, Minnesota in the south. The villages of Pepin, Maiden Rock and Stockholm are on the Wisconsin side, while Frontenac State Park takes up a large part of the Minnesota side. The largest city on the waterfront is Lake City, Minnesota.
The Canadian Pacific Railway now owns the former mainline of the Milwaukee Road on the Minnesota side, and the Burlington Northern's former Burlington Route mainline is lakeside on the Wisconsin side. Both were former racetracks for the premier passenger trains of their owners, and the CP rails still carry Amtrak's Empire Builder between Chicago and the Pacific Northwest. Lakeside highways are U.S. Route 61 on the Minnesota side, and across the lake Wisconsin State Highway 35 is just inland from the railroad. Both are National Scenic Byways and parts of the Great River Road.
Lake Pepin occupies a valley carved by the waters of Glacial River Warren, which drained Lake Agassiz in a catastrophic flood at the end of the last Ice Age, and to a lesser extent from Lake Duluth, a smaller glacial lake which drained through the present valley of the St. Croix River. When the continental glacier's meltwaters found other outlets to the sea, River Warren was succeeded by the more modest Upper Mississippi, which drains a much smaller basin, and the St. Croix spillway became the present river. Over a long period of time, the deep valley was partially filled with sediments, forming a broad floodplain. In this plain Lake Pepin formed behind a delta comprising sediments deposited into the ancient lake bed by the Chippewa River near the present community of Wabasha at the southern end of the lake. The lake backed up behind this sediment dam as far north as the location of Saint Paul. In the 10,000 years since the lake's creation, ongoing sedimentation into Lake Pepin has caused its upper end to migrate downstream some 80km (50mi) to its present location east (river direction south) of Red Wing, Minnesota.
The process of sedimentation continues at an accelerated rate; particulates carried by the river upstream are deposited when the current slows where the river empties into the lake. Pepin's natural flora are threatened by these increased rates of sedimentation, leading the Lake Pepin Legacy Alliance to call the phenomenon a "wet desert." Some theorize the lake is filling in at a rate of ten times greater than pre-colonization, due largely to increased run-off from farms along the Minnesota River. Other research maintains sediment accumulation is from a more diverse and complicated series of processes, including natural bank sloughing of large amounts of soil from steep river banks, a result of the geography of the area, composition and physical properties of the soil, man-made restriction of river flooding, access to flood plains and wetlands, and forced straightening an deepening of river channels. Research suggests these processes are being heightened due to increasing precipitation due to climate change.
The lake was first named in a map of New France made by Guillaume Delisle at the request of Louis XIV of France in 1703. The lake was named for Jean Pepin who settled on its shores in the late 1600s after exploring the Great Lakes from Boucherville.
Nicolas Perrot erected the first of a number of fur trade posts, Fort Saint Antoine, in 1686. In 1727 René Boucher de La Perrière and Michel Guignas built Fort Beauharnois on the lake. In 1730 it had to be rebuilt on higher ground. Boucher was the military leader and Father Guignas was a missionary to the Sioux.
In the nineteenth century the lake was used to transport freshly-cut trees for the lumber industry. Cut logs were floated across the lake, from the 1840s often with the assistance of steamboats to counter adverse winds and the sluggish currents in the lake. Large rafts were assembled at Reads Landing at the southern end, and towed downstream to mills at Winona and St. Louis.
In 1922, Lake City native Ralph Samuelson invented the sport of water skiing on the lake, and Lake City is known as "the birthplace of waterskiing." The city celebrates with a festival called Waterski Days every year on the last weekend in June.
Lake Pepin is the lake that Laura and her family visit in the "Going to Town" chapter of Little House in the Big Woods, the first book in Laura Ingalls Wilder's Little House series. Laura's family and their covered wagon then cross the frozen Lake Pepin in the chapter "Going West", the first chapter of the second book, Little House on the Prairie.
