Take a Virtual Tour

The Reserve, with the help of Laura Jean Media Services, have created a virtual tour of the Estuarium exhibit space. Enjoy, explore, and experience the Estuarium from the comfort of wherever you are.


The Lake Superior Reserve is expanding opportunities for volunteer docents in the Estuarium. Volunteers receive training on logistics of staffing the Estuarium and on interpretation and education skills. We are seeking volunteers passionate about their interaction with the Estuarium and/or with the St. Louis River Estuary itself.

Request an Education Program

Group visits with an interpretive lesson can be arranged by filling out the Education Request Form. Filling out a form does not guarantee availability though the education team aims to accommodate requests with at least one month advance notice.


This public science and interpretive learning center was created with funding from the National Oceanic and Atmospheric Association (NOAA), University of Wisconsin-Superior and the University of Wisconsin–Madison Division of Extension. Thank you to the Friends of the Lake Superior Reserve volunteers for supporting staffing at the Estuarium.
