Bank Midwest News & Resources
What Makes Okoboji Home
Okoboji’s story dates back to the 19th century, when settlers built homes and businesses along the shores after a bridge connected West and East Okoboji in the 1860s, and formally became a township in 1922.
Today, Okoboji is home to less than 800 residents, but attracts hundreds of thousands of tourists from all over the state every year to enjoy the waters and shorelines of West Okoboji Lake, one of Iowa’s Great Lakes.
Industries That Move Okoboji Forward
Dickinson County’s economy is powered by a strong mix of tourism, manufacturing, healthcare, retail, and agriculture. While the Iowa Great Lakes drive a thriving hospitality and recreational industry, year-round stability comes from manufacturing and healthcare employers. Together, these industries create a dynamic local economy that supports both seasonal businesses and long-term growth.
Things to Do Around Okoboji
As part of the greater northwest region of Iowa, Okoboji is home to Iowa’s Great Lakes, which spans 13,000 acres of water and more than 70 miles of shoreline. Visitors can make memories across a multitude of attractions, dining, outdoor recreational activities and watersports around Okoboji.
Lake Okoboji
West Lake Okoboji is one of just three natural blue-water lakes in the world. Known for its clear waters, the lake is a popular recreational destination for tourists and locals alike, offering opportunities for boating, skiing, fishing, swimming, and lakeside dining.
