The headwaters of the mighty Mississippi River flow through Camp Ripley, a military facility that serves as the National Guard training center for Minnesota and six surrounding states. Straddling 50 miles of the Mississippi River, the area also includes the watersheds of four major tributary rivers, making it one of Minnesota’s most important sources of drinking water. Its 45,000 acres of open water support many fish, animal, and bird species, as well as recreational opportunities for residents, tourists, and outdoor enthusiasts.
