My grandfather, Francis Edward Moulmby was born March 8, 1882 in Madison, Lak County, South Dakota. Was this slough named after him or one of his children? Says Susan
You'll need more than a day to explore everything Molumby Slough has to offer, you can camp at Madison Mobile Acres. This is a popular place for folks from Nunda. A lake close by is Lake Madison, and if you need a place to stay AmericInn Madison is a good choice. This lake is so wonderful.
You could also stop at Herman Slough if you're here at Molumby Slough; it's nearby. Stay the night at Walker's Point State Recreation Area, and a journey here wouldn’t be complete without a trip to close by Oakwood Lakes State Park.
