A remnant of the Ice Age dating back 13,000 years, East Okoboji Lake is a 743-hectare natural body of water and is the longest and third largest lake in the Iowa Great Lakes chain of lakes. Named by the Dakota people, who once called the shores of the lake their home, East Okoboji Lake is relatively shallow at just 10 feet, which makes it quieter than its neighbors regarding watersports. It is, however, a popular fishing destination due to its abundance of bullheads, and sees more relaxing pursuits such as boating, sailing, and swimming. The western shoreline of the lake is home to Elinor Bedell State Park, which features camping grounds, picnic areas, a network of hiking and mountain biking trails, and boat ramps for small craft.
