From Wikipedia, the free encyclopedia.
Lake Pepin is a naturally occuring lake, a widening of the Mississippi River on the border between Minnesota and Wisconsin. The formation of the lake was caused by the backup of water behind the sedimentary deposits of the Chippewa River's delta. It has a surface area of about 40 square miles and an average depth of 18 feet. In 1922, Ralph Samuelson invented the sport of water skiing on the lake. The largest city on the waterfront is Lake City, Minnesota, though the wide area stretches from Bay City, Wisconsin in the north down just past Pepin, Wisconsin in the south, just upstream from where the Chippewa River enters the Mississippi. The cities of Maiden Rock and Stockholm also border on the Wisconsin side, while Frontenac State Park takes up a large part of the Minnesota side.
