In 2017, the Decatur Lake Golf Course was put on the market. In 2018, a group of philanthropic donors with an interest in conservation purchased the land. The goal of the new owner, the Southern Wisconsin Land Conservancy, was to restore the natural oak savanna, prairie, and wetland landscapes of the river valley to continue to bring natural beauty and pleasure to all citizens as public open space and as a place to gather, celebrate, and learn about restoring ecosystems and healthy watersheds.
