Severson Dells Nature Center is one of six partners in the 815 Outside initiative. 815 Outside provides two resources to help people find their place to get outside in Winnebago County. The first is the 815 Outside website and the second is the 815 Outside Facebook page. There is a growing body of research that shows the positive mental and physical health benefits of spending time in nature and Winnebago County is fortunate enough to have almost 20,000 acres of publicly accessible green space.
