Lake Pepin, Natural lake on Mississippi River between Minnesota and Wisconsin, US
Lake Pepin is a natural widening of the Mississippi River spanning between Minnesota and Wisconsin, with depths and widths that vary throughout its length. The lake supports a diverse fishery and provides multiple locations where people can access the water for different activities.
The lake was named in 1703 on a French map in honor of Jean Pepin, an early settler in the area. Its formation resulted from sediment accumulation that created a natural obstruction in the Mississippi River valley.
Ralph Samuelson invented water skiing here in 1922, an event that led Lake City to celebrate this local achievement with an annual festival. The lake became known as the birthplace of a popular water sport that spread across the world.
The lake can be accessed from multiple locations along both shores, making it easy to find a spot to enter the water. Conditions vary by season, so planning your visit around the type of fishing or activity you prefer will improve your experience.
The lake formed when sediment from the Chippewa River created a natural barrier that trapped water in the Mississippi valley. This geological process produced a rare type of river-formed lake that has remained stable for centuries.
